Preparation method of ecological water-permeable concrete
The invention discloses a preparation method of ecological water-permeable concrete, the ecological water-permeable concrete comprises a water-permeable concrete base layer, a water-permeable concrete surface layer and a finishing coat, and the water-permeable concrete comprises the following raw materials in parts by weight: 100-120 parts of aggregate, 50-100 parts of metallurgical industry steel slag, 300-400 parts of cement, 10-15 parts of admixture, 3-10 parts of admixture, 0.5-2 parts of toner and 40-50 parts of water. Fly ash, polycarboxylate-type high-performance water reducing agent and anti-crack fiber are blended into the concrete, so that the connection strength between the aggregate and the metallurgical industry steel slag is enhanced, the anti-crack fiber can be well dispersed in the water-permeable concrete and has high tensile strength, the connection strength of connection points between the steel slag and gravel is improved, the generation and development of maintenance cracks of the water-permeable concrete can be effectively prevented, so that the compression resistance and fracture resistance of the water-permeable concrete are improved.
本发明公开了生态透水混凝土制备方法，该生态透水混凝土包括透水混凝土基层、透水混凝土面层以及罩面层，该透水混凝土原料及其重量份如下：包括100～120份的骨料、50～100份的冶金工业钢渣，300～400份的水泥、10～15份的掺合料、3～10份的外加剂、0.5～2份的色粉以及40～50份的水。本发明通过将粉煤灰、聚羧酸系高性能减水剂和抗裂纤维融入混凝土中，加强了骨料与冶金工业钢渣之间的连接强度，抗裂纤维能够很好的在透水混凝土中进行分散，且其具有高强的抗拉强度，增加了钢渣与碎石之间连接点的连接强度，能够有效防止透水混凝土的维系裂缝的产生和发展，进而提升了该透水混凝土的抗压抗折性能。
