High-strength pervious concrete for pavement surface layer and preparation method of high-strength pervious concrete
The invention discloses high-strength pervious concrete for a pavement surface layer, which is prepared from 411 to 435 parts of cement, 16 to 17 parts of cementing material, 124 to 131 parts of water, 65 to 67 parts of first aggregate, 17 to 226 parts of second aggregate, 420 to 438 parts of third aggregate and 795 to 829 parts of fourth aggregate, and the particle sizes of the first aggregate, the second aggregate, the third aggregate and the fourth aggregate are gradually increased; the method comprises the following steps: firstly, stirring corresponding cement, cementing material and water for 1-2 minutes; then adding corresponding parts of the first aggregate, the second aggregate, the third aggregate and the fourth aggregate, continuously stirring for 3-4 minutes to obtain a concrete mixture, and subsequently inserting, tamping and compacting to form a high-strength water-permeable concrete block; the pervious concrete is reasonable in design, and the component proportion design of the pervious concrete is optimized, so that the compressive strength of the pervious concrete is improved while the pervious effect of the pervious concrete is ensured.
本发明公开了一种用于路面面层的高强透水混凝土，包括水泥411～435份、胶结料16～17份、水124～131份、第一骨料65～67份、第二骨料17～226份、第三骨料420～438份、第四骨料795～829份，所述第一骨料至第四骨料的粒径逐渐增大；该方法包括以下步骤：先将相应分水泥、胶结料和水进行搅拌1min～2min；之后加入相应份第一骨料、第二骨料、第三骨料、第四骨料继续搅拌3min～4min，得到混凝土拌合物，并后续插捣和击实形成高强透水混凝土块；本发明设计合理，透水混凝土组分配比设计出发优化，从而保证透水混凝土的透水效果下提高透水混凝土的抗压强度。
