Curing agent as well as preparation method and application thereof
The invention provides a curing agent as well as a preparation method and application thereof, and particularly relates to the technical field of construction waste recovery and treatment. The curing agent comprises aerated concrete powder, red brick powder, gypsum plaster board powder and an exciting agent. The exciting agent comprises at least one of anhydrous sodium silicate, anhydrous sodium sulfate, triethanolamine and polyacrylamide. According to the curing agent provided by the invention, the main components of the aerated concrete are CaO and SiO2, the main components of the red brick are SiO2 and Al2O3, the main component of the gypsum plaster board is CaSO4, the three kinds of powder react with water to generate hydrated calcium silicate and hydrated calcium aluminate, the hydrated calcium silicate and the hydrated calcium aluminate further react to generate ettringite, the generation of hydration products is accelerated under the action of the exciting agent, and the curing effect is improved. Therefore, the curing effect is achieved.
本发明提供一种固化剂及制备方法和应用，具体涉及建筑垃圾回收处理技术领域。该固化剂，包括加气混凝土粉末、红砖粉末、纸面石膏板粉末和激发剂。所述激发剂包括无水硅酸钠、无水硫酸钠、三乙醇胺和聚丙烯酰胺中的至少一种。本发明提供的固化剂，其中加气混凝土的主要成分是CaO、SiO2，红砖主要成分是SiO2、Al2O3，纸面石膏板的主要成分是CaSO4，三种粉料遇水相互反应生成水化硅酸钙和水化铝酸钙，两者进一步反应生成钙矾石，在激发剂的作用下，加快水化产物的生成，从而起到固化作用。
