Calcium sulphosilicate-coal gangue geopolymer and preparation method thereof
The invention discloses a calcium sulphosilicate-coal gangue geopolymer and a preparation method thereof, calcium sulphosilicate is doped into coal gangue, a Ca-O bond, an Al-O bond and a Si-O bond are broken and condensed under the action of an alkali activator to form C (A)-S-H gel, and thus the coal gangue geopolymer with excellent early strength performance is prepared. According to the method, the coal gangue is used as a main raw material to prepare the calcium sulphosilicate-coal gangue geopolymer, the use amount of the coal gangue is as high as 90%, the problem that the alkali-activated coal gangue geopolymer is low in early strength is solved, the coal gangue is utilized to the maximum extent, and therefore a foundation is provided for high value-added application of the coal gangue.
本发明公开了一种硫硅酸钙‑煤矸石地聚物及其制备方法，将硫硅酸钙掺入至煤矸石中，在碱激发剂的作用下Ca‑O键，Al‑O键，Si‑O键断裂缩合形成C(A)‑S‑H凝胶，从而制备得到早期强度性能优异的煤矸石地聚物。本发明以煤矸石为主要原料制备硫硅酸钙‑煤矸石地聚物，煤矸石用量高达90％，解决了碱激发煤矸石地聚物早期强度低的问题，并最大程度对煤矸石进行利用，从而为煤矸石的高附加值应用提供基础。
