四川省河川纵横,石灰石遍地,为生产蒸压灰砂砖提供了得天独厚的有利条件。为了进一步提高灰砂砖质量,降低其石灰用量,南江县建材化工厂于1985年初开始研制一种灰砂砖外加剂。经在广汉县、巴中县、合川、灌县等灰砂砖厂反复使用,证实该种外加剂具有降低石灰用量20～30%或提高灰砂砖强度、减少用水量、节约能源之功能,可以在蒸压灰砂砖行 The rivers and rivers in Sichuan Province, with limestone everywhere, provide unique advantages for the production of autoclaved lime sand bricks. In order to further improve the quality of lime-sand bricks and reduce the amount of lime, Nanjiang County Building Materials Chemical Factory began to develop a lime-sand brick admixture in early 1985. After repeated use at lime-sand brick factories such as Guanghan County, Bazhong County, Hechuan County, and Guanxian County, it was confirmed that this additive has the function of reducing lime usage by 20 to 30% or increasing the strength of lime-sand bricks, reducing water consumption, and saving energy. Can be used in autoclaved lime sand bricks
