摘要
为研究水泥颗粒粒度分布分形维与其胶砂抗压强度的关系,利用粒度分布分形维的计算模型分析了有关文献报道的10种水泥颗粒粒度分布分形维值,结果表明:定量表征其分形特征的分形维值在2.325～2.435之间,各水泥颗粒粒度分布具有分形特征;分析了水泥颗粒粒度分布分形维值与水泥3d抗压强度、28d抗压强度的关系,分析表明:化学组成和矿物组成基本相同的条件下,水泥颗粒粒度分布分形维与水泥胶砂的3d、28d抗压强度具有较好的正线性相关关系。
The particle size distributional fractal dimensions of ten different samples of cement were calculated by the mathematic model, which was used to investigate the relationship between the particle size distributional fraetal dimension of cement particles and the compression strength of cement mortar. The results indicated that, the particle size distributional fractal dimensions of cement particles reported in the references were varied from 2.325 to 2.435, and the particle size distribution of cement particles had fractal characterization. The relationship between the particle size distributional fractal dimension of cement particles and 3 and 28 days compression strength of cement mortar were analyzed, the results showed that the relationship between the particle size distributional fractal dimension and the compression strength of cement mortars was positive linearity for the cements with nearly same components.
