Preparation process of high-compression-resistance light weight foam concrete
The invention discloses a preparation process of high-compression-resistance light weight foam concrete. The preparation process comprises the following steps: preparing active mixing materials: uniformly mixing river sand, glass fiber, a naphthalenesulfonate water reducing agent and active silica; preparing slurry: controlling by an automatic foamed cement equipment mainframe, and respectively injecting water, cement, an active mixing material and a propylene organic thickener according to the proportion through a water pump and a material injector in a double-shaft mixer in a mixing state, wherein the water adding frequency, the material injecting frequency and the power input frequency of a stirring engine are controlled within the range of 0-70 HZ; preparing foam with a foaming agent; controlling by the automatic foamed cement equipment mainframe, and preparing foam with the foaming agent through a plunger pump and an air compressor; mixing and pouring the prepared mixed slurry in a moulding die. Concrete prepared by the preparation process has the advantages of being better in sound insulation and heat insulation effects, and excellent in compression resistance and the like.
