High-strength alkali-inhibiting construction waste regenerated water permeable brick and preparation method thereof
The invention relates to a high-strength alkali-inhibiting construction waste recycled water permeable brick, which comprises a base layer and a surface layer, and the base layer comprises the following raw material components by weight: 50-80 parts of construction waste recycled coarse aggregate, 5-20 parts of construction waste recycled fine aggregate, 15-30 parts of cement, 3-15 parts of fly ash, 8-10 parts of water, 0.02-1.0 part of a reinforcing agent, and 0.02-1.0 part of an alkali inhibitor. The surface layer comprises the following raw material components in parts by weight: 70-85 parts of natural sand, 15-30 parts of cement, 0.02-1.0 part of a reinforcing agent and 0.02-1.0 part of an alkali inhibitor. According to the recycled water permeable brick prepared from the construction waste recycled aggregate, reduction and recycling of waste construction waste are achieved, and the recycled water permeable brick is green, energy-saving, high in porosity, high in water absorption, free of saltpetering, high in water permeability and high in compressive strength, the water permeability coefficient can reach 2.0 * 10 <-2 > cm/s or above, and the compressive strength can reach 40 MPa or above.
本发明涉及一种高强抑碱建筑垃圾再生透水砖，包括基层和面层，所述基层包括如下重量份的原料组分：建筑垃圾再生粗骨料50～80份、建筑垃圾再生细骨料5～20份、水泥15～30份、粉煤灰3～15份、水8～10份、增强剂0.02～1.0份、抑碱剂0.02～1.0份，所述面层包括如下重量份的原料组分：天然砂70～85份、水泥15～30份、增强剂0.02～1.0份、抑碱剂0.02～1.0份。本发明采用建筑垃圾再生骨料制成的再生透水砖，实现了废旧建筑垃圾的减量化和资源化，绿色节能、孔隙率高、吸水性强、不泛碱，透水系数可达2.0×10‑2cm/s以上，透水性高，抗压强度可达40MPa以上，抗压强度高。
