What is Foam Concrete and CLC Blocks? CLC blocks consist of foam concrete. In this article we will learn more about the types of foam concrete as well as how they can be used. We will also discuss their density and strength. Aerated concrete blocks a…
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.…
In the summer when the temperature is high and the air humidity is low, due to the accelerated hydration reaction at high temperature, the moisture is easy to evaporate, the mortar fluidity loss is fast and the setting time is shortened, the construc…
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…
The commonly used superplasticizers include polycarboxylate series, naphthalene series, fatty acid series, and other superplasticizers.…
