Inert concrete waste slurry solidified body material and preparation method thereof
The invention relates to the technical field of building materials, and especially relates to an inert concrete waste slurry solidified body material and a preparation method thereof. In the invention, second-grade fly ash and S95-grade slag are active raw materials and excited raw materials; an excitant is anhydrous sodium carbonate powder and sodium metasilicate pentahydrate powder, the alkali excitant is dissolved in water-containing waste slurry and excites the activity of the excited raw materials, so that the strength is developed to form a solidified body, the concrete waste slurry subjected to homogenization treatment is used as an auxiliary raw material, and internal particles of the concrete waste slurry can be uniformly filled in holes in the solidified body, therefore, the harmless treatment of the concrete waste slurry is realized. Meanwhile, compared with a traditional cement material, the curing effect on the waste concrete slurry is better, the porosity of a cured body material is low, the microstructure is denser, the mechanical strength is high, and the high-temperature stability is better.
本发明涉及建筑材料技术领域,尤其涉及一种惰性混凝土废浆固化体材料及其制备方法。本发明中,二级粉煤灰和S95级矿渣是活性原料,是被激发原料;激发剂是无水碳酸钠粉末和五水偏硅酸钠粉末,碱激发剂在含水废浆中溶解并激发被激发原料的活性,从而发展强度形成固化体,而经均质化处理的混凝土废浆作为辅助原料,其内在颗粒可以均匀填充于固化体中的孔,从而实现混凝土废浆的无害化处置。同时,本发明对混凝土废浆的固化效果相比于传统水泥材料更加优良,固化体材料的孔隙率低、微观结构更密实、力学强度高且高温稳定性能较优。
