Study on High-Efficiency Complexed Foaming Agent for Lightweight Foamed Concrete
The introduction of foam into concrete, made the concrete have a small internal, closed independent uniform bubbles, which can form light weight, good insulation properties of foamed concrete, mainly used for roofing, non-load-bearing walls and thermal insulation layer pipeline. The purpose of this study is to obtain basic data on the properties of the development of lightweight foamed concrete containing a novel and high-efficiency foaming agent for various applications. The results show that this novel complex foaming agent have high foam expansion and stable foam. Lightweight foamed concrete based on LC foaming agent exhibits high compressive strength, low thermal conductivity and low water absorption after 28-day curing. Furthermore, it can be found that micropores is homogenously distributed into the LC foamed concrete with density of 400kg/m3.
