Regenerated pervious concrete and preparation method thereof
The invention discloses recycled pervious concrete and a preparation method, and the recycled pervious concrete is prepared from the following raw materials in parts by weight: 800 to 1050 parts of coarse aggregate, 300 to 420 parts of recycled aggregate, 400 to 550 parts of cement, 300 to 500 parts of water and 6.1 to 8.9 parts of polyvinyl alcohol, 6.7-10.1 parts of silicon carbide is added, so that the bending strength, freeze-thaw resistance and permeability of the concrete are improved; on the basis, polyvinyl alcohol is added, so that the cohesive force of the concrete is improved, the cohesive force among the cement, the aggregate and the fly ash is enhanced, the dispersion uniformity of silicon carbide in the concrete raw material mixing process can be improved, and the bleeding tendency of the concrete after the silicon carbide is added is reduced; therefore, the addition amount of the silicon carbide is increased, the strength improvement effect of the silicon carbide on the concrete is further improved, and the regenerated pervious concrete with good strength is obtained.
本申请公开了一种再生透水混凝土和制备方法，其再生透水混凝土，包括以下重量份数的原料：粗骨料800~1050份，再生骨料300~420份，水泥400~550份，水300~500份，聚乙烯醇6.1~8.9份；碳化硅6.7~10.1份碳化硅加入提升混凝土的抗弯强度、耐冻融性能和渗透性能；再此基础上再加入聚乙烯醇，加入提升混凝土的粘结力，使得水泥、骨料和粉煤灰之间的粘结力增强，并且还可提升碳化硅在混凝土原料混合过程中的分散均匀性以及减少混凝土受碳化硅加入后出现的析水趋势，由此使得碳化硅加入量提升且碳化硅对混凝土的强度改善效果进一步提升，由此获得一种强度好的再生透水混凝土。
