Ardealite building material and preparation method thereof
The invention discloses an ardealite building material and a preparation method thereof, the ardealite building material comprises an alkaline excitation material, fly ash and an unsaturated carboxylic acid water reducing agent, and the water reducing agent can exert the original water reducing effect of the water reducing agent; meanwhile, slow release of Ca < 2 + > in the semi-hydrated phosphogypsum is facilitated, so that the retarding effect is achieved, fly ash vitreous body dissociation is accelerated, the hydration process is accelerated, formed unsaturated carboxylic acid and a complex serve as filler, gaps between gel material crystals can be filled, and the material is reinforced. Compared with a common polycarboxylic acid water reducer, the ardealite building material disclosed by the invention is better in retarding effect, and the mechanical property of an obtained building material test piece is better.
本公开公开了磷石膏建筑材料及其制备方法，其中磷石膏建筑材料中包含碱性激发材料、粉煤灰和不饱和羧酸减水剂，减水剂可以发挥其原本减水的效果，同时有利于半水磷石膏中Ca2+缓释从而起到缓凝效果、加快粉煤灰玻璃体解离加快其水化进程、形成的不饱和羧酸与的配合物作为填料可以填补凝胶材料晶体之间的缝隙，对材料起到补强的作用。相比于使用普通的聚羧酸减水剂，本公开的磷石膏建筑材料缓凝效果更优，得到的建筑材料试件力学性能更优。
