用烧石膏提高复合水泥强度的理论研究

Theoretical study on enhancing the compound cement strength with burnt with burnt anhydrite

文章作者在进行二水石膏和烧石膏物化特性研究基础上，重点对烧石膏的结构与水化物力学特性及烧石膏对复合水泥孔隙率和孔分布的影响进行了试验研究，从而得出结论：烧石膏晶体活性高，用作缓凝剂制成的水泥，其早期强度有明显提高。

The structure and hydrated dynamic feature of the burnt anhydrite were tested，and the impact of the burnt anhydrite upon the porosity and hole distribution of compound cement was studied，based on the studies about physical and chemical features of gypsum and burnt anhydrite . The conclusion is: the burnt anhydrite crystal is highly active , and the early strength of the cement mixed with it as a retarder can be increased remarkably .
