摘　　要：为了解玄武岩纤维和橡胶粒对混凝土孔径分布的影响情况,测定了混杂掺入玄武岩纤维和橡胶粒的混凝土孔径及其百分比。利用多重分形理论对其进行分析,结果表明,混凝土孔径分布的多重分形谱参数D1/D0和Δβ能够反映出混凝土孔径分布的非均匀程度,且掺入60kg/m3的2mm橡胶粒和2.0kg/m3的玄武岩纤维时,混凝土孔结构改善效果显著。In order to find out the influence situation of basalt fiber and rubber particles on concrete pore size distri- bution, concrete pore diameter and its percentage mixed with basalt fiber and rubber particles were measured. Using multi- fractal theory to analyze, the results show that, multifractal parameters of concrete pore size distribution such as D1/D0 and Aft could be reflected by heterogeneity degree of concrete pore size distribution, the improvement of concrete pore struc- ture is obvious by mixing 2mm rubber particles of 60kg/m3 and basalt fiber of 2.0kg/m3.
