摘要
石膏硬化体的缺点是强度低、耐水性差。掺入普通硅酸盐水泥后形成的低溶解度、高结合力水硬性物质——钙矾石和水化硅酸钙可以穿插生成于石膏的多孔结构中,发挥其针状结构及与其他物质交叉、共生而产生增强作用的优势,从而改善硬化体性能。
For the characteristics that the gypsum hardening body strength is low, the water resistance is bad,the study begins from the hardening body structure and hydration products,which adding an appropriate amount of incorporation of ordinary portland cement to form a low solubility, high water-binding capacity of the hard material -- calcium Ettringite and C-S-H. These substances generate interspersed in the porous structure of gypsum, to play its needle-like structure and with other cross-substances. It plays a role in enhancing the strengths, to improve the performance of hardened body.
