陈晓梅,王文华
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。
Abstract: In order to find out the influence situation of basalt fiber and rubber particles on concrete pore size distribution, concrete pore diameter and its percentage mixed with basalt fiber and rubber particles were measured. Using multifractal theory to analyze, the results show that, multifractal parameters of concrete pore size distribution such as D1/D0 and Δβ could be reflected by heterogeneity degree of concrete pore size distribution, the improvement of concrete pore structure is obvious by mixing 2mm rubber particles of 60kg/m3 and basalt fiber of 2.0kg/m3.
