硅酸盐混凝土硅酸盐混凝土是人工石材的一种,由主要为水化硅酸钙成分的胶结料将矿物质的骨料胶结而成。硅酸盐混凝土的主要原料为石灰和石英砂。大部分石灰可以用磨细的冶金渣、锅炉渣、页岩粉、霞石浆以及其他含有硅酸钙和铝酸钙化合物的工业废渣来代替。此时混合物中掺入的石灰和石膏起活化剂的作用。除石英砂外,尚可使用长石砂和其他砂,以及天然或人选多孔骨料、砂砾混合料等。
Silicate Concrete Silicate concrete is a type of artificial stone made by cementing mineral aggregates with a binder that is mainly composed of calcium silicate hydrates. The main raw materials for the silicate concrete are lime and quartz sand. Most of the lime can be replaced with finely ground metallurgical slag, boiler slag, shale fines, nepheline, and other industrial wastes containing calcium silicate and calcium aluminate compounds. The lime and gypsum incorporated in the mixture at this time act as activators. In addition to quartz sand, feldspathic sand and other sands, as well as natural or candidate porous aggregates, grit mixtures, etc. can be used.
