It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete? 1. The cement problem: Some workers in construction will add more water for a more fluid co…
CLC Blocks and foamed Concrete, two new energy-saving materials, are leading the construction industry reform. As environmental awareness continues to improve, the construction industry is now focusing on more energy-saving and environmentally friend…
Foam concrete blocks are made from foam that is mixed with a cement-sand mix as well as made use of as a building product. They are less costly than traditional cinder block and also are immune to fracturing. They are also environment-friendly. Howev…
What is a concrete lathering representative? Concrete foaming representative, likewise called foam concrete lathering representative, concrete lathering representative describes can lower the surface area tension of the liquid as well as produce a mu…
What is Foam Concrete and CLC Blocks? CLC blocks consist of foam concrete. In this article we will find out more about different kinds of foam concrete along with the areas they can be used. We will also discuss their density and strength. Aerated co…
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.…
