摘要
将不同细度的硅酸盐水泥与粉煤灰掺配,利用灰色关联理论,研究了胶凝材料颗粒细度与粉煤灰水泥胶砂强度间的关系。结果表明:适当增大粉煤灰的比表面积以及水泥与粉煤灰间比表面积的差异,可使粉煤灰-水泥胶凝体系获得较高的强度;适当降低水泥的比表面积,对于提高水泥混凝土的长期性能是有利的。
Portland cement and fly ash of different fineness were mixed.Theory of grey connection analysis was used to study the correlation between the particle fineness of cementitious materials and the strength of fly ash-cement mortar.Results showed that high strength could be achieved for fly ash-cement system by increasing the specific surface area of fly ash and the difference of specific surface area between cement and fly ash properly.Long-term properties of cement concrete may be improved by decreasing the specific surface area of cement properly.
