Recycled aggregate concrete and preparation method thereof
The invention relates to the technical field of concrete materials, in particular to recycled aggregate concrete and a preparation method thereof. The recycled aggregate concrete is prepared from thefollowing components in parts by weight: 70-90 parts of Portland cement, 45-65 parts of water, 140-180 parts of broken stone, 30-45 parts of waste concrete powder gel slurry, 110-130 parts of sand, 15-20 parts of diatomite powder, 15-20 parts of additional auxiliaries, 3-5 parts of a polycarboxylate superplasticizer, 0.5-1 part of melamine, 0.5-1 part of sodium dodecyl benzene sulfonate and 1-2 parts of polyvinyl acetate emulsion. The recycled aggregate concrete provided by the invention has excellent crack resistance, impermeability and compressive strength and good durability, realizes efficient recycling of waste concrete, and has good economic benefits. The preparation method of the recycled aggregate concrete is simple and efficient in process, convenient to operate and easy to control, convenient to operate and control, stable in quality of prepared products and convenient for industrial large-scale production.
本发明涉及混凝土材料技术领域，具体涉及一种再生骨料混凝土及其制备方法。所述再生骨料混凝土包括以下重量份的组分硅酸盐水泥70‑90份、水45‑65份、碎石140‑180份、废旧混凝土粉凝胶浆30‑45份、砂110‑130份、硅藻土粉15‑20份、外加助剂15‑20份、聚羧酸减水剂3‑5份、三聚氰胺0.5‑1份、十二烷基苯磺酸钠0.5‑1份、聚醋酸乙烯乳液1‑2份。本发明的再生骨料混凝土具有优良的抗裂性、抗渗性和抗压强度，耐久性好，实现废旧混凝土的高效再利用，具良好的经济效益。本发明的再生骨料混凝土制备方法工艺简单高效，操作方便易控，操作控制方便，制备的产品质量稳定，便于工业化大生产。
