Coal gangue-based light high-strength unfired ceramsite and preparation method thereof
The invention discloses coal gangue-based light high-strength unfired ceramsite and a preparation method thereof, and relates to the technical field of preparation of building materials. The gangue-based light high-strength unfired ceramsite is prepared from the following components in parts by weight: 30 to 40 parts of gangue, 20 to 30 parts of cement, 30 to 50 parts of a composite admixture, 40 parts of water, 0.5 to 2 parts of an air entraining agent, 0.05 to 0.2 part of a foam stabilizer, 0.1 to 0.25 part of a waterproof agent and 0.5 to 2.0 parts of carboxymethyl cellulose. The coal gangue, the steel slag and the high-calcium fly ash selected in the invention have relatively high content of SiO2 and Al2O3, the slag contains a large amount of CaO, the industrial byproduct gypsum promotes generation of ettringite by exciting the slag, a silicon-aluminum compound is depolymerized under the action of alkalinity and sulfate, and is subjected to hydration reaction with alkaline components, so that the content of the silicon-aluminum compound is reduced; and polymerizing to generate gelling hydration products such as hydrated calcium silicate gel, hydrated calcium aluminosilicate gel and the like.
本发明公开了一种煤矸石基轻质高强免烧陶粒及其制备方法，涉及建筑材料制备技术领域。煤矸石基轻质高强免烧陶粒包括如下重量份组分：煤矸石30~40份，水泥20~30份，复合掺和料30~50份，水40份，引气剂0.5~2份，稳泡剂0.05~0.2份，防水剂0.1~0.25份，羧甲基纤维素0.5~2.0份。本发明所选择的煤矸石、钢渣和高钙粉煤灰具有较高含量的SiO2和Al2O3，矿渣含有大量的CaO，工业副产石膏通过激发矿渣促进钙矾石生成，硅铝化合物在碱性和硫酸盐作用下发生解聚，并与碱性成分发生水化反应，再聚合生成水化硅酸钙凝胶、水化硅铝酸钙凝胶等胶凝性水化产物。
