Preparation method of geopolymer building block excited by carbide slag and mirabilite
The invention provides a preparation method of a geopolymer building block excited by carbide slag and mirabilite. According to the principle of a fly ash geopolymer preparation process, the raw materials of the method mainly comprise industrial solid waste carbide slag, mirabilite, fly ash, desulfurized fly ash and water, and the geopolymer building block is prepared by the steps of ball milling, screening, mixing, stirring, forming and curing. According to the invention, the carbide slag, mirabilite and other solid wastes are adopted to replace traditional liquid caustic soda and a water glass solution as an exciting agent to excite silicon-aluminum substances in the fly ash, so that on one hand, the use of cement can be reduced, the emission of CO2 can be reduced, and on the other hand, the obtained geopolymer building block has good performance, meets the requirements of building blocks, reduces the cost of producing geopolymer building blocks obviously, reduces the use and transportation cost of the exciting agent, and meanwhile, realizes the cyclic utilization of the solid waste carbide slag and mirabilite. The prepared geopolymer building block has good use performance.
本发明提供一种电石渣及芒硝激发的地聚物砌块的制备方法，根据粉煤灰地聚物制备过程的原理，该方法原料主要包括工业固废电石渣、芒硝、粉煤灰、脱硫灰、水，采用球磨、筛分、混合、搅拌、成型、养护工序制成。本发明中采用电石渣和芒硝等固废代替传统的液碱和水玻璃溶液做激发剂来激发粉煤灰中硅铝物质，一方面可以减少水泥的使用，减少CO2的排放，另一方面得到的地聚物砌块具有良好的性能，满足砌块的要求，显著降低了生产地聚物砌块的成本，降低激发剂的使用和运输成本，同时实现了固废电石渣和芒硝的循环利用。制备所得地聚物砌块具有良好的使用性能。
