蒸压灰砂砖是采用85％黄砂和15％石灰为原料,经配料,加水搅拌,消化,压制成型,高压饱和蒸气养护而成的一种墙体建筑材料,质量优于粘土砖和免烧砖的墙体材料,是一种硅酸盐制品。在国外,最早研究的是英国,始于1866年,到1898年法国建成世界上第一家灰砂砖厂,并于1908年发表了灰砂砖工业标准。我国在1913年广州就建立了裕益灰砂砖厂,1958年以后北京、包头、重庆、广州都陆续办起了灰砂砖厂,广州产
Autoclaved sand-lime brick is a kind of wall building material made of 85% yellow sand and 15% lime as raw material, mixed with water, stirred with water, digested, pressed and formed, and cured by high-pressure saturated steam, and its quality is better than that of clay brick and no-burning. The brick wall material is a silicate product. In foreign countries, the earliest research was in the United Kingdom. It began in 1866, and in 1898, France built the world’s first lime-sand brick factory. In 1908, it published the industrial standards for sand-lime bricks. Our country established the Yuyi lime-sand brick factory in Guangzhou in 1913. After 1958, Beijing, Baotou, Chongqing, and Guangzhou all established lime sand brick factories in succession.
