摘　　要：通过对透水岩棉吸水、透水以及保水能力的研究,初步探讨了密度对岩棉水处理能力的影响。结果表明:三种不同密度的透水型岩棉最大体积吸水率均可达到90%以上,且密度越小,吸水能力越佳;透水型岩棉作为新型的透水材料,其透水系数可达0.35cm/s^0.78cm/s远高于透水砖标准,且密度越小,透水能力越强;不同密度的透水岩棉具备不同的保水性能,密度越大,保水能力越好,但在标准试验环境下三者的体积吸水率与时间均呈线性递减关系。In this paper, the effects of density on water-processing ability are studied by means of research on waterabsorption, permeability and retention capacity of permeable rock wool. The result shows that the maximum volumeof water absorption of the three kinds of permeable rock wool with different densities can reach more than 90%, andit becomes stronger with low density. As a novel permeable material, the permeation coefficient of permeable rockwool is up to 0.35 cm/s-0.78 cm/s, which is considerably higher than permeable brick standard, and the permeabili-ty also becomes stronger as the density decreases. Different densities of permeable rock wool have different water re-tention capacities, and the bigger the density is, the stronger the retention capacity, while their specific absorption ofvolume is negatively correlated with time in a standard experimental environment.
