Environment-friendly regenerated brick and preparation method thereof
The invention provides an environment-friendly regenerated brick and a preparation method thereof. The preparation raw materials comprise sludge dewatering and drying mud cakes, reclaimed sand, cement, a polycarboxylic acid water reducing agent, water glass, sodium bentonite and water. According to the environment-friendly regenerated brick, sludge dehydration and drying resource utilization work is promoted, the additional value of sludge dehydration and drying mud cakes is improved, a large number of natural gravel resources are saved while a large number of sludge dehydration and drying mud cakes are consumed. The prepared recycled unfired solid brick has the characteristics of good compressive strength, low energy consumption and high production efficiency, the compressive strength can reach 32 MPa, the strength requirement of JG/T 505 construction waste recycled aggregate solid bricks is met, and the recycled unfired solid brick can be widely applied to municipal roads and house construction. The invention also provides a preparation method of the environment-friendly regenerated brick.
本发明提供了一种环保再生砖及其制备方法。制备原料包括淤泥脱水干化泥饼、再生砂、水泥、聚羧酸减水剂、水玻璃、钠基膨润土和水。本发明的环保再生砖，既推动了淤泥脱水干化资源化利用工作，提高了淤泥脱水干化泥饼附加值，消耗大量淤泥脱水干化泥饼的同时节约了大量天然砂石资源。本发明制备的再生免烧实心砖抗压强度好、耗能少，生产效率高的特点，其抗压强度可达32MPa，符合JG/T 505建筑垃圾再生骨料实心砖强度要求，可广泛用于市政道路、房产建设。本发明还提供了环保再生砖的制备方法。
