Modified waste brick recycled aggregate and preparation method thereof, recycled aggregate water permeable brick and recycled aggregate concrete block
The invention provides a modified waste brick recycled aggregate and a preparation method thereof, a recycled aggregate water permeable brick and a recycled aggregate concrete block, and relates to the technical field of building materials. The modified waste brick recycled aggregate comprises waste brick particles and a wrapping layer wrapping the surfaces of the waste brick particles, the preparation raw material of the wrapping layer comprises cement; the mass ratio of the waste brick particles to the cement is (0.1-0.2): (0.2-0.35). The cement is adopted to modify the waste brick particles, so that the water absorption rate of the waste brick particles is reduced, and meanwhile, the apparent density and the stacking density of the waste brick particles are improved. Results of the embodiment of the invention show that the modified waste brick recycled aggregate has a water absorption rate of 12.5-19.6%, an average crushing index of 26-29% and an average void ratio of 44-46% when absorbing water for 1 h. The waste brick particles are modified, the utilization rate and the additional value of the waste bricks are increased, and the land occupancy rate is reduced.
本发明提供了一种改性废弃砖再生骨料及其制备方法、再生骨料透水砖和再生骨料混凝土砌块，涉及建筑材料技术领域。本发明所述改性废弃砖再生骨料，包括废弃砖颗粒和包裹在废弃砖颗粒表面的包裹层；所述包裹层的制备原料包括水泥；所述废弃砖颗粒和水泥的质量比为0.1～0.2:0.2～0.35。本发明通过采用水泥对废弃砖颗粒进行改性，降低了废弃砖颗粒的吸水率，同时提高了废弃砖颗粒的表观密度和堆积密度。由本发明实施例结果可知，改性废弃砖再生骨料吸水1h时的吸水率为12.5～19.6％，平均压碎指标为26～29％，平均空隙率为44～46％。本发明对废弃砖颗粒进行改性，提高了废弃砖的利用率和附加值，减少了土地占用率。
