Many friends have a vague and often confused understanding of concrete and mortar. Today, let’s explore the essence and difference between the two in detail.

The difference between mortar and concrete:

Cement mortar is a mixture of cement, sand and water. It has no aggregate and cannot form a strong skeleton and is difficult to withstand strong loads. In construction projects, cement mortar is used for foundation and wall masonry, as a binder for block masonry materials, such as rubble and red brick. And also cement mortar is used for indoor and outdoor plastering Ash.

Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Ordinary concrete is an artificial stone that is hardened by mixing cement, coarse aggregate (crushed stone or pebble), fine aggregate (sand), admixture and water.

Concrete has the characteristics of workability, high strength, deformability and durability.

Compared with the two, concrete has much greater bearing capacity and durability. Concrete mixed with a large amount of mortar will affect the bearing cage capacity of the concrete structure, destroy the safety performance of the structure, and also make the concrete poor in homogeneity, resulting in inconsistent shrinkage of various parts of the concrete. And it is easy to produce concrete shrinkage cracks, reducing the concrete impermeability and durability of frost resistance .

To product and convey concrete or mortar is not an easy job on construction sites when the required amount is especially large. So you need special tools to fulfill the work. Here are some machines recommended for various needs of concrete materials and mortar mixture, including pump trailer, boom pump, and mixer pump machines, etc.

Mortar properties

1. The workability of freshly mixed mortar

The workability of mortar refers to the mortar ability that can easily spread into a uniform and continuous thin layer on the surface of masonry and other surfaces, and is closely bonded to the base layer. Including two aspects of fluidity and water retention.

(1) Liquidity
The factors affecting the fluidity of mortar mainly include the type and amount of cementitious materials, the amount of water, and the type, particle shape, thickness and gradation of fine aggregates.
In addition, it is also related to the variety and dosage of mixed materials and additives.

Usually, the substrate is a porous water-absorbing material or construction job is under dry and hot conditions, a mortar with high fluidity should be selected. On the contrary, if the substrate absorbs less water, or the construction is under wet and cold conditions, the mortar with low fluidity should be selected.

(2) Water retention
Water retention refers to the ability of the mortar to retain water. The mortar with poor water retention will cause bleeding and slurries during use, which will make the mortar and the substrate not firmly bonded.And due to the loss of water, the normal bonding and hardening of the mortar will be affected. The strength of the mortar will be reduced.

1. The main factors affecting the water retention of mortar are the type and amount of cementitious materials, the type, fineness and water consumption of sand. Mixing powdered mixed materials such as lime paste and fly ash into the mortar can improve the water retention of the mortar.

2.Strength of hardened mortar

The factors that affect the strength of mortar are: when the quality of raw materials is constant, the strength of mortar mainly depends on the grade of cement and the amount of cement.

In addition, mortar strength is also affected by sand, admixture, mixed materials and masonry and maintenance conditions.
When the content of mud and other impurities in the sand is large, the strength of the mortar is also affected.

Properties of Concrete

1. Workability refers to the convenience of the operation of various construction procedures in the concrete mixture under certain construction conditions, so as to ensure the performance of uniform and dense concrete. Workability is a comprehensive technical index, including three main aspects: fluidity (consistency), cohesion and water retention.

2. Strength is the main mechanical property of concrete after hardening, which reflects the quantitative ability of concrete to resist load. Concrete strength includes compressive, tensile, shear, flexural, flexural and grip strengths. Among them, the compressive strength is the largest and the tensile strength is the smallest.

3. The deformation of concrete includes deformation under non-load action and deformation under load action. The deformation under non-loading action includes chemical shrinkage, wet and dry deformation and temperature deformation. Too much cement can easily cause chemical shrinkage inside the concrete and cause fine cracks.

4. Concrete durability refers to the ability of concrete to resist various damage factors under actual use conditions and maintain the strength and appearance integrity for a long time. Including the frost resistance, impermeability, corrosion resistance and carbonation resistance of concrete, etc.

Electric powered concrete pumps and also diesel powered concrete pumps are both most typical types of concrete pumping devices. The greatest distinction between the two is its power method. So is the electric power system far better or the diesel power system? A couple of straightforward analyses are offered below.

1. The usage cost of the electric power pump is a lot lower than that of the diesel power pump. The diesel power blending trailer pump requires to take in concerning 1 dollar of diesel oil to pump 1m ³ of concrete, while the diesel power concrete distribution pump eats a lot more. With the increase in oil rates, the usage price of diesel power is regularly raising.

2. The quantity and weight of diesel motor are larger than those of electrical motors. For that reason, during the design procedure, larger racks need to be designated. By doing this, the volume as well as weight of the concrete pump will be further raised.

3. The diesel motor has solid power, high gas utilization price as well as secure system efficiency. It is a generally utilized power device for large-scale heavy industrial machinery and also tools.

4. The cost of firmware for diesel-powered concrete delivery pumps is greater than that of electrical pumps. Compared with the concrete pump in the shop, the diesel powered concrete delivery pump is not just various in the main power parts. To guarantee the normal procedure of the transfer pump, the control box, hydraulic control system, frame structure as well as other power structures are additionally various. Two diesel power pumps and also electric power pumps with the exact same power, the price of the diesel pump is $6,000 to $7,500 yuan greater than that of the motor pump.

5. Yet the electric power pump has fairly high needs on the power grid. Not only a high-power transformer, but likewise a steady power supply voltage is required. If the voltage is lower than 20% of the ranked voltage after the start-up is finished, and also it does not go back to the ranked voltage for a long time, under hefty tons, the electric motor will be melted because of extreme stator copper loss and also extreme warmth. For most rural areas as well as some communities, it is still hard to satisfy steady power supply. If a generator set is geared up, this will lead to a rise in transportation prices and usage costs.

To summarize, the choice of electrical power pump or diesel power pump ought to be based on the real circumstance of the own task, the financial scenario, the construction area of the task and also lots of aspects of the target consumer. Analyze the advantages of the pump and make a final decision.

Asphalt concrete pavement has many advantages such as good driving comfort, excellent performance, fast construction speed and low maintenance cost. Therefore, most of the highways of all levels use asphalt pavement. Hot mixed asphalt mix is the main method and the key link of the current asphalt pavement construction. It mainly relies on advanced mixing equipment – asphalt mixing plant to fully heat and mix the high-quality composite materials through scientific and reasonable configuration to achieve accurate and even road mixture materials. Since the asphalt mixture is so useful, it is necessary to have a deep understanding of the production process of asphalt mixture. Of course, this is also the basic requirement for people in the asphalt industry. This article will give a detailed description below. Fore more knowledge of asphalt plant, you can ask itsasphaltplant for help.

How does an asphalt Plant Work

After the central control room sends the start-up command, the cold material in the cold bin is conveyed to the drying drum by the belt conveyor. The dried aggregate is conveyed to the vibrating screen by the hot material elevator for screening, and the screened aggregate falls into each hot bin room. Each aggregate and powder falls into its own weighing bucket from its own chamber door and is measured by an electronic scale, then put into the mixing tank, and the weighed hot asphalt is sprayed into the mixing tank; After all kinds of mixtures are fully mixed, the finished asphalt mixture is formed and unloaded into the hopper car; The feeding hopper car is unloaded into the finished asphalt mixture storage bin through the track, and finally the finished materials are placed on the transport truck through the unloading gate. The transportation, drying and screening of aggregate, the transportation of powder and asphalt are continuous, while the weighing of aggregate, powder and asphalt, the mixing of mixture and the transportation of finished materials by the hopper truck are carried out periodically. Above is how does an asphalt plant mix materials.

 

 

Disassembly Analysis of Asphalt Production Process

Central Control Room: This part is the core component of asphalt mixing station.

Mobile concrete pump, light in dimension, portable in framework, simple to run, economical, efficient and also quick, stable and also trusted, with strong pumping capability, is among the most popular construction equipment.

So, what should we do when buying a portable pump for sale? The following are some points that commonly need to consider when acquiring, and also wish to aid you.

1. Brand

Buy products from well-known brands so the top quality is assured. With the production company’s sales company or the manufacturing business’s local sales workplaces. Request the identification certification of the purchased item, the test report, the examination record of the unique lorry examination project, the automobile catalog number, the top quality system certification, and so on. It is far better to send out an unique individual to the manufacturing business to examine its production, monitoring and top quality. as the basis for the choice of items.

2. Job Item

According to the circumstance of the job undertaken and also the dimension of the equipment building job, the size of the cycle and also the regularity of transfer, the larger pumping volume, the parameters of the dispersing arm and the ideal chassis are identified.

When inspecting product quality, it needs to be from the outside to the within. The initial is whether the appearance, bonded steel architectural parts, paint, strolling systems, railings are smooth.

And after that gradually go deeper inside the machine.

The performance quality of accessories such as chassis engine, gearbox, transfer axle, pumping system, distributing arm, primary hydraulic parts, slewing system and slewing bearing.

3. Engineering site setting

If it is outdoors and there is no power supply, it is best to use a diesel penalty stone concrete pump. If there is a power supply, it is much more inexpensive to use an electrical pump.

4. Investment Spending Plan and Item Price

Exactly how to choose an ideal concrete pump? The most vital point is the price for consumers. Nevertheless, the cost is the first photo of the consumer.

If a heavy machinery is at an extremely economical cost, customers will certainly not trust. Quality must be additionally one more crucial choice for customers to select concrete pumps. Item top quality problems are carefully pertaining to after-sales issues. The product high quality of a mobile concrete pump suppliers picked in the early stage is excellent, and there are couple of issues. Later on, in the process of usage, lots of will certainly be removed. Fixing the problem will certainly likewise save you a lot of cash.

5. Functioning Efficiency

Examine the performance of the item. The stability and adaptability of the activities of each component, as well as whether there is uncommon shivering in the expansion arm and also the healing arm. Whether the framework driving, transforming size, technique angle, departure angle, tiny ground clearance fulfill the opportunity needs.

Whether the economic indicators such as the fuel consumption rate of the engine are reasonable, as well as whether the push-button control operation is trustworthy and also stable. For the item of the boom putting arm, you should additionally thoroughly explain the manufacturing quality of its structural parts.

In order to decrease the weight of the boom arm, base framework and outrigger. The steel must be made from high-strength, fine-grained carbon steel (relieved and also solidified steel sheet). The welding procedure needs are really rigorous, or else there will be serious issues such as weld breaking.

6. Important technological specifications

Normally, a portable concrete distribution pump has the major technical parameters: distribution displacement, electrical outlet stress, electric motor power and also distribution valve form. According to the brand-new international standard, these primary parameters can be known from the model of the portable concrete delivery pump.

According to the significant outlet stress degree, it is divided right into low pressure pump (≤ 5MPa), medium stress pump (6-10MPs) and also high pressure pump (>10MPa). Most concrete pumps can accomplish two-speed variable variation or stepless variable.

Customers ought to select the outlet pressure according to the real needs of the job and the height of the conveying range. Select the range of the output square according to the capacity of mixing and also feeding. Choose the type of the distribution shutoff according to the accumulated condition of the pumped concrete.

The motor power of a pump is the prerequisite for determining the electrical outlet stress and the shipment volume. Under the condition of a specific motor power, the rise of the pressure will certainly lower the distribution volume. However, lowering the electrical outlet stress will certainly minimize the delivery quantity.

In order to make sure that the concrete pump has a large delivery quantity, a particular outlet pressure and also a matching financial power, in the style of the portable concrete delivery pump, a continuous power pump is mostly made use of that is the constant power value after option when the outlet stress increases, the outcome variation of the oil pump will immediately reduce to reach the value corresponding to the power layout. If the outlet stress is to be high, and also the pouring quantity is wanted to be large. The only way is to enhance the motor power.

7. Key Components of The Pump Machine

The hydraulic pump is the “heart” of the concrete pump. According to the different origins, there are residential hydraulic pumps as well as imported hydraulic pumps.

According to the framework of the hydraulic pump, there are equipment pumps, vane pumps, as well as plunger pumps.

Hydraulic pumps similarly appropriate for various stress levels. Because of its affordable and strong habit, equipment pumps are extensively utilized in the preliminary concrete pumps. But due to their little stress bearing and also big pulse resistance, they are normally configured on low-pressure pumps, or utilized in medium as well as high-pressure pumps.

Supporting oil circuit system: plunger pump is separated into swash plate type and likely shaft type, which is extensively made use of now due to its huge stress range.

As a result, from the grade of the hydraulic pump, you can peek at the feature of a portable pump for sale.

Hydraulic shutoff is the “assistant” of hydraulic pump, consisting of sequence shutoff, stress lowering shutoff, reversing shutoff, dumping shutoff, one-way shutoff and changing valve, etc.

If a hydraulic shutoff team stops working, it will affect the action of the whole machine. Consequently, when buying a concrete pump, not only the “heart” but also its “assistant” need to be taken into consideration to accomplish the most effective arrangement.

Electrical components: The electric elements on the concrete pump consist of contactors, breaker, relays, etc, which act according to logic programs as well as control the work of related components. Although domestic electrical elements have a benefit in cost, there is still a void in between the integrity and life of parts from imported or joint endeavor brands.

8. Quality Control as well as After-sales Service

When buying items, unique attention ought to be paid to whether the manufacturer has given a reputable quality assurance dedication and also excellent after-sales service products. For specialist heavy building and construction machinery, trustworthy as well as full guarantee service will be a strong backing for the success of our building jobs.

9. Comprehensive Evaluation

In addition to selecting from the “hardware” devices of the concrete pump, it is also required to examine the level of its “software program”: such as the brand name’s manufacturing background, research and development stamina, customer service capacities, and so forth. Routine large enterprises have excellent efficiency in research and development strength, quality assurance, customer service and also spare parts supply, which can eliminate customers from fears.

As discussed over, it is difficult to acquire a truly appropriate concrete pumping devices. It requires thorough consideration, careful computation, and contrast. In short, I hope you can discover the ideal concrete pumping product.
