On-site pouring foam concrete thermal insulation roof is the method of on-site pouring, and the foam concrete thermal insulation layer is directly constructed on the roof.
The aqueous solutions of various foaming agents are used in the fields of concrete, magnesite, gypsum, urea-formaldehyde resin, etc. by using the foam produced by the foaming machine. Because the bubbles are easily broken, it affects the effect of foaming agent to some extent. Any substance that can improve bubble stability and prolong the half-life of bubble collapse can be called a foam stabilizer.
The main mechanism that redispersible latex powder improves the workability of foamed concrete is: the foam stabilizing effect of latex powder increases the bubble volume of foamed concrete. At the same time, it plays a role of lubrication. When the latex powder is dispersed, it protects the colloid against water. The affinity of the foamed concrete and the subsequent increase in the viscosity of the foamed concrete improve the cohesive force of the foamed concrete during the in-situ pouring process, so as not to disturb the dynamic foam, so the workability of the foamed concrete is greatly improved.
The operability of construction machinery is also very important. Ideal construction machinery and a high-quality construction team will play a decisive role in the improvement of product quality.
Influence of Water-liquid Mixing Ratio and Construction Site Management on the Construction of Cast-in-Place Foam Concrete
Foam concrete is a mixed gel of various materials and admixtures. Different materials of raw materials, different material mixing ratios, different properties of admixtures, different water-to-liquid mixing ratios, different operation levels of construction machinery and construction personnel, different construction environments and curing conditions will all bring about the quality of foam concrete products.
