摘要
比较了两种不同矿物组成、不同粉磨细度的硅酸盐水泥的密实容重、净浆标准稠度用水量、胶砂流动度和胶砂抗压强度同X·n的关系及水泥物理性能同X、n和比表面积之间的关系。结果表明 ,在所用试验样品的范围内 ,X·n同本文所做水泥各项性能具有很好的相关性 ,且对某些性能具有再现性 ,其相关性优于单独的X、n以及比表面积。在本文所用样品的n值范围内和水泥颗粒组成范围内 ,水泥最佳颗粒组成的X、n的乘积值在20μm左右 ,此时的水泥比表面积在367m2/kg 左右 ,相应的颗粒组成约为≤6μm ,27 % ;≤12μm ,42 %;≤24μm ,63 %。
Effect of the compact bulk density, water demand for normal consistency, mortar flow rate and compressive strength of Portland cement with different mineral composition and fineness on the coefficient X·n and relationship between cement physical properties and its specific surface area and X, n value have been analyzed in this paper The results indicate that under testing conditions, parameter X·n has good correlation with the properties of cement, some possess good reproducibility The correlation for X·n is better than X, n or specific surface area as independent parameter Within the scope of cement particle size distribution and sample number n, the X·n value for the optimum particle size distribution is determined to be around 20μm The corresponding specific surface area for cement is about 367m2/kg and resultant particle size composition is 27%≤6μm, 42%≤12μm, and 63%≤24μm
