由衡阳市硅酸盐制品厂、衡阳市建材研究所共同研制成功的水泥、石灰、砂加气混凝土砌块是以砂、石灰、水泥为主要原料,加入少量石膏,以铝粉为发气剂,经过磨细、配料、浇注、保温静停、切割、蒸养等一系列工序制成的一种多孔轻质建筑材料。具有轻质、保温、吸音性能好和可锯、可刨等优点。产品已在框架轻板、框架填充、旧楼加层、砌块承重等21幢楼房约3万多平方米建筑上使用,反映良好,产品各级指标均达到原建材部部颁标准要求。产品技术指标如下: 容重500级 The cement, lime and sand aerated concrete block jointly developed by Hengyang Silicate Product Factory and Hengyang Building Material Research Institute are mainly made of sand, lime and cement, and a small amount of gypsum is added, and aluminum powder is used as a gas generating agent. , A kind of porous lightweight building material made through a series of processes such as grinding, batching, pouring, heat preservation static stop, cutting and steaming. It has the advantages of light weight, heat preservation, sound absorption, sawing and planing. The products have been used in more than 30,000 square meters of 21 buildings such as frame light board, frame filling, old building plus layer, block bearing, etc. The products are well reflected and the products at all levels have reached the standard requirements of the original building materials department. Product technical indicators are as follows: Weight Rating 500
