Concrete prepared from construction waste, and preparation method thereof
The invention discloses a concrete prepared from construction waste, and a preparation method thereof, and belongs to the technical field of construction waste resource utilization. Raw materials aremixed according to a certain ratio of cement: water: sand: construction waste fine aggregate (pre-wetting treatment): macadam: construction waste coarse aggregate (pre-wetting treatment): admixture of1: (0.45-0.61): (0.68-1.10): (0.68-1.10): (1.51-2.05): (1.51-2.05): 0.03, and are stirred to form the strength-grade C20-C30 construction waste recycled concrete which can be used for and is not limited to construction road surface layers. The stress performance of the recycled concrete is further improved, the prepared recycled concrete has the strength grade of C20-C30, the current situation that most enterprises prepare low-strength concrete products from construction waste can be improved, and the recycled concrete has a good effect when applied to pavement surface layers.
本发明公布了一种建筑垃圾制备的混凝土及其制备方法，属于建筑垃圾资源化利用技术领域，它采用配合比按照水泥:水:砂:建筑垃圾细骨料（预湿处理）:碎石:建筑垃圾粗骨料（预湿处理）:外加剂=1:（0.45‑0.61）:（0.68‑1.10）:（0.68‑1.10）：（1.51‑2.05）:（1.51‑2.05）:0.03的成分，混合后搅拌形成强度等级C20‑C30建筑垃圾再生混凝土，可用于且不仅限于施工道路面层。本发明进一步提高了再生混凝土的受力性能，本发明制备的再生混凝土具有C20‑C30强度等级，可改善大多企业将建筑垃圾制备低强度混凝土产品的现状，应于路面面层具有良好效果。
