【摘要】 把实际水泥体系的粒径分布看作灰色系统,测定了不同粒径分布水泥的各龄期抗压强度,用灰色系统理论的关联度计算法定量表示了不同大小颗粒对不同龄期强度贡献的差异,提出了在实际生产中寻求最佳粒径分布的一个指导性原则。更多还原

【Abstract】 Paricle sise distribution of real cement system is considered as a gray system. Compressive strengths of cements with different particle size distributions in different hydra- tion ages are measured. The differences of strength contributions devoted by different particles to cement paste in different hydration ages are demonstrated quantitatively with the gray con- trol system theory. A guiding principle for seeking the optimal particle size distribution of ce- ment at factory is proposed.更多还原
