干硬性石膏混凝土由建筑石膏、石灰、缓凝剂——微生物生产废渣、填充料——砂和水组成。最佳组分按试件抗压强度计算,最低含水率为7%。石灰在混合物中可控制水化过程和材料结构形成过程中的动力学以及坯体水化相的组成,这些对制品最终的物理力学性能产生作用。有机混合物缓凝剂在水化晶体表面形成延缓混合物硬化的不溶解的薄膜。 Dry gypsum concrete consists of building gypsum, lime, retarder—microbial production waste residue, filler—sand and water. The best component is calculated according to the compressive strength of the specimen, and the minimum moisture content is 7%. Lime in the mixture controls the dynamics of the hydration process and the formation of the material structure, as well as the composition of the hydration phase of the green body, which has an effect on the final physical and mechanical properties of the product. The organic mixture retarder forms an insoluble film on the surface of the hydrated crystal that retards the hardening of the mixture.
