Construction waste baking-free recycled brick and preparation method thereof
The invention provides a construction waste baking-free recycled brick and a preparation method thereof, wherein the raw materials comprise a cementing material and aggregate, the aggregate is recycled aggregate formed by treating construction waste, the cementing material is pump concrete waste residue, and cement is doped in the raw materials of the construction waste baking-free recycled brickas an excitant. The preparation method comprises the following steps: (1) weighing a cementing material and aggregate according to a mixing ratio of raw materials for later use; (2) mixing the cementing material and the aggregate in proportion to obtain a mixture; (3) putting the uniformly stirred mixture into a mold, carrying out compression molding on a molding machine by adopting proper pressure and loading speed, and immediately removing the mold after molding; and (4) carrying out carbonization maintenance or steam maintenance on the recycled brick subjected to form removal for a certainperiod of time to obtain the baking-free recycled brick. According to the invention, the purpose of waste resource utilization is achieved, environmental pollution can be effectively reduced, the manufacturing cost is reduced, and raw materials are easy to obtain; and the preparation method is simple and reasonable, reduces air pollution and is suitable for large-scale industrial production.
本发明提供了一种建筑垃圾免烧再生砖及其制备方法，原料包括胶凝材料和骨料，骨料为建筑垃圾处理而成的再生骨料，其特点是：胶凝材料为泵送混凝土废渣，建筑垃圾免烧再生砖的原料中掺加水泥作为激发剂。制备方法包括：（1）按原料配合比称取胶凝材料和骨料，备用；（2）将胶凝材料和骨料按比例混合得到混合料；（3）将搅拌均匀的混合料装入模具，在成型机上采用适当压力与加荷速度压制成型，成型后立即拆模；（4）将拆模后的再生砖进行碳化养护或蒸汽养护一定时间后，得到免烧再生砖。达到废物资源化利用的目的，能够有效地减少环境污染，降低制造成本，且原料易得；制备方法简单、合理，减少空气污染，适用于大规模工业化生产。
