Water-permeable concrete and preparation method thereof
The invention discloses water-permeable concrete and a preparation method thereof, and belongs to the technical field of concrete. The water-permeable concrete is mainly prepared from the following raw materials in parts by weight: 245 to 356 parts of ordinary Portland cement, 765 to 865 parts of gravels, 217 to 243 parts of river sand, 20 to 30 parts of polymer emulsion, 3.5 to 4.25 parts of a water reducing agent and 71.5 to 97.5 parts of water. The polymer emulsion is at least one of ethylene-vinyl acetate copolymer emulsion and styrene-acrylic emulsion. According to the water-permeable concrete disclosed by the invention, a reasonable ratio of the gravels to the river sand to the polymer emulsion is set, so that the polymer emulsion can be dispersed between the gravels and river sand particles, but water-permeable pores among the particles cannot be blocked, the strength of the concrete is improved, and the water permeability of the concrete is guaranteed.
本发明公开了一种透水性混凝土及其制备方法，属于混凝土技术领域。本发明的透水性混凝土，主要由如下重量份数的原料制成：普通硅酸盐水泥245‑356份、碎石765‑865份、河砂217‑243份、聚合物乳液20‑30份、减水剂3.5‑4.25份、水71.5‑97.5份；所述聚合物乳液为乙烯‑醋酸乙烯共聚物乳液、苯丙乳液中的至少一种。本发明的透水性混凝土设置了合理的碎石、河砂与聚合物乳液的比例，使得聚合物乳液能够分散在碎石及河砂颗粒之间，但是又不会将颗粒间的透水孔隙堵塞，既提高了混凝土的强度，又保证了混凝土的透水性。
