摘要:
概括了水泥粉磨过程的一般性本质,依据模糊群子论的基本原理,导出了水泥体系粒径分布的群子本征方程φ/(1-φ)=K·(1+r_1W/(1-W))/(1+r_2(1-W)/W),得到3个具有明确物理意义的群子参数K、r_1、r_2,并将r_1·r_2/K定义为粒径分布的比分散度。实验及计算结果表明,水泥浆体各龄期抗压强度对r_1·r_2/K均有很好的依赖关系,可以用比分散度综合表征粒径分布对水泥性能的影响。

The general feature of the grinding process of cement is summarized, and the sub-cluster intrinsic equation for the particle size distribution is derived as φ/(1-φ)=K·[1_r_1·(?)/(1-W)]/[1+r_2·(1-W)/W] based on the fuzzy sub-cluster theory. Three sub-cluster parameters with explicit physical meaning are obtained and r_1·r_2/K is defined as the specific dispersion degree of particle size distribution. It is shown that the compressive strength of cement paste has a good correlation with the specific dispersion degree, and the effect of particle size distribution on mechanical properties of cement can be represented comprehensively by the specific dispersion degree.
