Pervious concrete based on steel slag and recycled aggregate and preparation method thereof
The invention discloses pervious concrete based on steel slag and recycled aggregate and a preparation method thereof. The pervious concrete is prepared from the following components in parts by weight: 700 to 800 parts of coarse aggregate, 175 to 190 parts of cement, 15 to 18 parts of silicon powder, 5 to 10 parts of slag powder, 22 to 28 parts of an additive, 8 to 10 parts of toughening fibers and 60 to 70 parts of water, wherein the coarse aggregate is composed of recycled aggregate and steel slag, and the particle size of the coarse aggregate is 5-10mm; the cement is P.O42.5 grade ordinaryPortland cement; the additive is prepared from an ethylene-vinyl acetate copolymer, nano clay and phosphogypsum; and the toughening fibers are steel fibers. The invention also provides a preparationmethod of the ecological concrete. The invention not only ensures good water permeability and durability of the pervious concrete, but also provides an application method of industrial products such as steel slag and recycled aggregate, and has an environment-friendly prospect of ecological sustainable development.
本发明公开了一种基于钢渣与再生骨料的透水混凝土及其制备方法，该透水混凝土由以下组分按重量份组成：粗骨料700～800份、水泥175～190份、硅粉15～18份、矿渣粉5～10份、外加剂22～28份、增韧纤维8～10份、水60～70份。所述粗骨料由再生骨料和钢渣组成，粒径为5～10mm；所述水泥为P.O42.5级普通硅酸盐水泥；所述外加剂由乙烯‑醋酸乙烯酯共聚物、纳米黏土、磷石膏调制而成；所述增韧纤维为钢纤维。本发明还提供了该生态混凝土的制备方法。本发明不仅保证了透水混凝土良好的透水性和耐久性，还提供了一种对工业产物钢渣和再生骨料的运用方法，具有生态可持续发展的环保前景。
