All-steel slag aggregate cement water permeable brick
The invention discloses an all-steel slag aggregate cement water permeable brick, which is prepared from the following raw materials in proportion: 429 kg/m<3> of cement, 241 kg/m<3> of water, 831 kg/m<3> of 3-10 mm steel slag gravel, 887 kg/m<3> of 0-5 mm steel slag sand and 3.4 kg/m<3> of a polycarboxylic acid high-efficiency water reducing agent, wherein the water-binder ratio is 0.26, and the designed void ratio is 10%. According to the invention, the porosity of the steel slag sandstone and the water absorption rate of the aggregate are both higher than those of natural sandstone, and the application of the steel slag as the aggregate to the preparation of the water permeable brick instead of the natural stone is feasible; and the water-retaining property of the all-steel slag aggregate cement-based water permeable brick is 0.7 g/cm<2>, and the wear resistance (the depth of a grinding groove is 28 mm) and the freezing resistance (the strength loss rate is 16.0%) all meet good requirements.
本发明公开了一种全钢渣集料水泥透水砖，由以下配比的原料制备而成：水泥429kg/m3，水241kg/m3，3～10mm钢渣碎石831kg/m3，0～5mm钢渣砂887kg/m3，聚羧酸高效减水剂3.4kg/m3，水胶比为0.26，设计空隙率为10％。本发明钢渣砂石的的孔隙率和集料的吸水率均比天然砂石高，钢渣作为骨料替代天然石料应用于透水砖的制备是切实可行的；全钢渣集料水泥基透水砖的保水性为0.7g/cm2、耐磨性(磨槽深度为28mm)以及抗冻性(强度损失率为16.0％)，均达到了良好要求。
