Preparation and Properties of Lightweight High-Strength Autoclaved Aerated Concrete
摘要
Abstract
In this paper,the preparation technology of lightweight high-strength autoclaved aerated concrete was studied by using typical solid waste resources such as fly ash and micro silica powder in Xinjiang.The effects of raw material ratio,water to material ratio and gas-generating agent content on the absolute dry density and compressive strength of products were analyzed.The results show that when m(fly ash)∶m(micro silica powder)∶m(quartz sand)∶m(quicklime)∶m(cement):m(gypsum)is 30∶25∶10∶25∶8∶2,the amount of aluminum powder is 0.10％of total material mass,the water to material ratio is 0.58,the autoclave temperature is 195 ℃,the autoclave pressure is 1.2 MPa,and the autoclave time is 8 h,the absolute dry density of lightweight high-strength autoclaved aerated concrete is 568.70 kg/m3,the compressive strength is 5.4 MPa,and the thermal conductivity is 0.140 W/(m·K),reaching the level of A5.0,B06.关键词
