摘要
透水混凝土是一种多孔、轻质的绿色生态建筑材料,其透水性和强度是一对相互矛盾的性能指标。研究掺入不同种类掺合料(粉煤灰、玄武岩纤维、EVA聚合物乳液)对透水混凝土强度和透水性能的影响,结果表明双掺粉煤灰与EVA聚合物乳液或玄武岩纤维与EVA聚合物乳液,能保证透水混凝土的透水性基本不变,提高抗压强度20%以上,提高抗折强度30%以上,实现透水混凝土强度增强;但是同时掺入三种掺合料不利于透水混凝土强度和透水性的提高。
Permeable concrete is a kind of porous, lightweight, green ecological building material, Permeability and strength are a pair of contradictory performance indicators. The effects of different types of admixtures （fly ash, basalt fiber, EVA polymer emulsion） on the strength and water permeability of permeable concrete were studied. The results show that the double-mixed fly ash with EVA polymer emulsion or basalt fiber with EVA polymer emulsion can ensure that the permeability of the permeable concrete is basically the same, the compressive strength is improved by more than 20%, the flexural strength is improved by more than 30% , to achieve enhanced strength of permeable concrete. But the incorporation of three kinds of admixtures is not conducive to the improvement of the strength and water permeability of the permeable concrete.
