Although the products produced by anti-crack mortar manufacturers are called anti-crack mortar, they often fail to achieve the effect of anti-crack when they are used. What is the reason for this?

I believe that many people know that reinforcement is needed in the construction of commercial permeable concrete, so do you know the advantages of reinforcement? Why do commercial pervious concrete use a reinforcing agent?

Pervious concrete is an eco-friendly concrete with continuous pores, good air permeability and water permeability. Pavement can supplement groundwater, alleviate urban waterlogging, absorb sound and reduce noise, improve urban thermal environment, and have good environmental and social benefits.

According to (GB8075-87) classification, concrete admixture according to its main function can be divided into four categories:
1, improve concrete mixing logistics variable performance admixture: including all kinds of water reduction liu, air entraining agent and pumping agent.

Concrete is to rely on cement cementation, gradually hardening, and improve the compressive strength. Because the knot of cement is not complete at a stroke, but with the increase of time and gradually perfect.

To ask why concrete should be divided into strength grades, we should first know what is concrete strength grade. Concrete strength grade is artificially divided according to the concrete cube compressive strength value, it is the characteristic strength of concrete.

Concrete raw materials are mixed with water to form concrete mixture, which has a certain fluidity, cohesion and plasticity. With the passage of time, the hydration reaction of the cementitious material continues, and the hydration products continue to increase, forming a condensed structure.

Concrete composition materials are generally cement, aggregate, water, mineral admixtures, chemical admixtures. For some concrete with special requirements, some special materials will be added according to the need.

In 2016, there was a family building a new house in our village. If the house leaks when it is finished. For leaks, maybe everyone is familiar with, such as one or two leaks on the roof, which has made people very upset.

Every wait by gelatinizing material, aggregate and water to cooperate by appropriate proportion mix the mixture that makes, the artificial stone material that gets after moulding harden via pouring again, collectively for concrete.

Check before operation: the control table of dry mortar mixing station should make the operator can see the work of each department, instrument indication signal is accurate and reliable, and the control table of electric dry powder mixing equipment should be filled with rubber board or dry wood.

1, the whole station structure is tight, beautiful, generous and environmental protection;
2. Small floor area and flexible layout;
3, modular combination, free of foundation installation; It is convenient and fast to disassemble, assemble and transport, and the cycle is short.
4, high production efficiency, low energy consumption;
