在毛主席关于“综合利用大有文章可做”的方针指引下,武汉第五砖瓦厂、湖北建筑工程学院和辽宁工业建筑设计院共同协作,利用粉煤灰为主要原料,掺入一定数最的石灰、水泥为胶凝材料,加入少量铝粉和辅助材料,经过搅拌、浇注发泡成型、蒸压养护等工序试制了一批加气混凝土砌块。粉煤灰采用武汉青山热电厂的湿排灰。经浓缩、真空过滤脱水处理后,其含水量为30%左右。细度4900孔筛余量小于10%,比表面积3210cm~2/g。比重1.9～
Under the guidance of Chairman Mao’s policy of “Utilizing a wide range of articles to do,” Wuhan No. 5 Brickyard, Hubei College of Architecture and Engineering, and Liaoning Industrial Architecture Design Institute collaborated to use fly ash as the main raw material and incorporate a certain number of them. The most lime and cement were cementitious materials. A small amount of aluminum powder and auxiliary materials were added, and a batch of aerated concrete blocks was trial-produced through stirring, pouring, foaming, and autoclaving. Fly ash adopts wet ash from Wuhan Qingshan Thermal Power Plant. After concentration, vacuum filtration and dehydration, the water content is about 30%. The fineness of 4,900 holes is less than 10%, and the specific surface area is 3210cm~2/g. Specific gravity 1.9～
