Construction waste recycled split decorative concrete brick and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to a construction waste recycled split decorative concrete brick and a preparation method thereof. The building waste recycled concrete is prepared from the following raw materials in parts by weight: 15-30 parts of cement, 40-130 parts of building waste recycled aggregate, 2-10 parts of a reinforcing agent and 2-10 parts of a water repellent, the preparation method is simple, the prepared product has relatively high compressive strength and relatively low water absorption, and the problem that the construction waste recycled aggregate is relatively difficult to be used for manufacturing split decorative concrete bricks due to the defects of poor strength, high powder content, high water absorption rate, easiness in breeding bacteria and the like is solved.
本发明属于混凝土技术领域，具体涉及一种建筑垃圾再生劈裂装饰混凝土砖及其制备方法。其原料包括以下原料水泥15‑30份、建筑垃圾再生骨料40‑130份，增强剂2‑10份，憎水剂2‑10份；制备方法简单，制成的产品具有较高的抗压强度，和较低的吸水性，并解决了因建筑垃圾再生骨料强度差、含粉量高、吸水率高和易滋生细菌等缺陷，较难用于制作劈裂装饰混凝土砖的问题。
