Sodium silicate powder exciting agent produced by melting method
The invention belongs to the technical field of building material exciting agents, and particularly relates to a sodium silicate powder exciting agent produced through a melting method. The sodium silicate powder exciting agent is prepared by taking waste incineration fly ash, glass powder and sodium hydroxide as reactants through heat treatment. The powdery exciting agent is prepared instead of a traditional solution form, the possibility of a single-component alkali activation binder system is achieved, the waste incineration fly ash is selected as one of the raw materials, the production cost of the exciting agent is greatly reduced, and therefore the cost of alkali activation concrete is reduced; according to the present invention, the utilization rate of the waste incineration fly ash in the building field can be improved, the cement consumption and the energy consumption are reduced, the problems of environmental pollution and land occupation caused by solid waste stockpiling are improved, the dual-carbon emission reduction is promoted, and the prepared alkali activation binder mortar has excellent compressive strength.
本发明属于建筑材料激发剂技术领域，更具体的，涉及一种熔融法生产硅酸钠粉末激发剂。本发明通过以垃圾焚烧飞灰、玻璃粉和氢氧化钠为反应物，经热处理制备得到硅酸钠粉末激发剂。本发明制备得到的是粉末状的激发剂，而非传统的溶液形式，实现了单组分碱活化粘结剂体系的可能，选用垃圾焚烧飞灰作为原料之一，大大降低了激发剂的生产成本，从而降低了碱活化混凝土的成本，可以提高垃圾焚烧飞灰在建筑领域中的利用率，在降低水泥使用量和能源消耗的同时，改善固废堆存造成的环境污染及土地占用问题，推动双碳减排，制备的碱活化粘结剂砂浆具有优异的抗压强度。
