Carbon sequestration type coal gangue foam concrete and preparation method thereof
The invention discloses carbon sequestration type coal gangue foam concrete and a preparation method thereof. The carbon sequestration type coal gangue foam concrete is prepared from the following raw materials in parts by weight: 20 to 60 parts of coal gangue powder, 40 to 80 parts of cement, 0.05 to 0.2 part of a foaming agent, 0.005 to 0.2 part of a foam stabilizer, 0.1 to 0.3 part of a water reducing agent and 30 to 150 parts of water. The coal gangue is crushed into powder, the coal gangue powder, the cement, the water reducing agent, the water and the like are used as main raw materials to be mixed, the prepared coal gangue foam concrete is good in fluidity, high in workability and moderate in quality, the strength meets the filling requirement, and the coal gangue foam concrete can be applied to mine filling scenes, so that the effective utilization rate of the coal gangue can be increased; the carbon sequestration effect of the foam concrete can be promoted, stable geological sequestration of CO2 gas can be realized, the climate change can be slowed down, and a new thought is provided for the development of green low-carbon building materials.
本发明公开一种固碳型煤矸石泡沫混凝土及其制备方法，所述固碳型煤矸石泡沫混凝土包含以下重量份原料：20～60份煤矸石粉、40～80份水泥、0.05～0.2份发泡剂、0.005～0.2份稳泡剂、0.1～0.3份减水剂和30～150份水。本发明将煤矸石破碎成粉，以煤矸石粉、水泥、减水剂和水等为主要原料进行混合，制备出的煤矸石泡沫混凝土流动性好，工作性强，质量适中，强度符合填充要求，可应用于填充矿洞的场景，既能提高煤矸石的有效利用率，降低煤矸石对生态环境的危害性，又能促进泡沫混凝土的固碳效能，实现CO2气体稳定的地质封存，有助于减缓气候变化，为绿色低碳建材发展提供新的思路。
