High-strength high-permeability full-aggregate steel slag water permeable brick and preparation method thereof
The invention provides a high-strength high-permeability full-aggregate steel slag water permeable brick and a preparation method thereof and relates to the technical field of building materials. Thehigh-strength high-permeability full-aggregate steel slag water permeable brick comprises the following components in parts by weight: 70 to 80 parts of coarse steel slag, 7 to 8 parts of steel slag sand, 15 to 20 parts of cement, 3 to 5 parts of water, 0.6 to 1.2 parts of a water reducing agent and 1 to 2 parts of acrylic resin, the strength grade of the full-aggregate steel slag water permeablebrick is C40, and the permeability coefficient is more than 2.5 mm/s. The preparation method comprises the following steps: 1) uniformly mixing and stirring cement, a small amount of water, steel slagsand and coarse steel slag to obtain a mixture, and 2) putting the mixture stirred in the step 1) into a mold, applying a pressure of 1MPa to the upper surface of the mixture, compacting the mixture,stabilizing the pressure for 3 minutes, and flattening the surface by using a spatula to obtain the test block. The invention solves the problem that the existing steel slag water permeable brick isdifficult to consider in the aspects of strength, water permeability coefficient, engineering cost and the like, promotes the utilization of a large amount of steel slag, realizes the sustainable development of the building resource environment, and protects and improves the urban ecological environment.
本发明提供一种高强度高渗透全集料钢渣透水砖及其制备方法，涉及筑材料技术领域，包括如下重量份的组分：粗钢渣70～80份、钢渣砂7～8份、水泥15～20份、水3～5份、减水剂0.6～1.2份、丙烯酸树脂1～2份，该全集料钢渣透水砖强度等级为C40，透水系数为2.5mm/s以上。其制备方法包括以下步骤：1)将水泥、少量水和钢渣砂、粗钢渣混合搅拌均匀，得到混合料；2)将步骤1)拌制完成的混合料装入模具中，在混合料上表面施压1MPa压力，使混合料压实，稳压3分钟后，用抹刀修平表面，得到试块。本发明解决了现有钢渣透水砖在强度、透水系数和工程造价等方面难以兼顾的问题，促进钢渣大宗量利用，实现建筑资源环境的可持续发展，保护和改善城市生态环境。
