Foam concrete blocks are made from foam that is mixed with a cement-sand mix and used as a building material. They are less expensive than conventional concrete blocks and are resistant to cracking. They are also environment-friendly. However, you sh…
What is Foam Concrete and CLC Blocks? CLC blocks consist of foam concrete. In this article we will know more about the various types of foam concrete as well as the places they are used. We will also discover their density and strength. Aerated concr…
Polycarboxylate superplasticizer is often used in concrete, which can reduce the water consumption of concrete while maintaining the same fluidity, thus improving the strength and durability of concrete.…
The bubbles in concrete above 100μm are called large harmful bubbles, 100 ~ 50μm are called harmful bubbles, 50 ~ 20μm are called low harmful bubbles or harmless bubbles, and those below 20μm are called beneficial bubbles.…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is…
At first, concrete additives were used only to save cement. With the development of construction technology, admixture has become the main measure to improve the performance of concrete.…
The wide application of mineral admixtures mainly derived from industrial solid wastes diversifies the composition of cementitious materials, which is one of the main characteristics of modern concrete.…
Adding polycarboxylate superplasticizer can make the compressive strength of precast concrete reach 40MPa grade at 8h to 18h.…
The impermeability of concrete is related to its porosity and pore structure.…
Thermal insulation materials refer to materials or material composites that have significant resistance to heat flow.…
The influence of water consumption is very obvious. In the actual application of concrete engineering, sometimes if the water consumption is increased by more 1~3kg/m3, the concrete will appear serious bleeding phenomenon, which will cause defects su…
Foam concrete natural maintenance can be divided into two types: cover-up sprinkler maintenance and plastic film maintenance.…
