Low-carbon high-performance reclaimed sand concrete as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and discloses low-carbon high-performance recycled sand concrete as well as a preparation method and application thereof, and each cubic meter of concrete comprises the following raw materials in parts by mass: 300-350 parts of cement, 120-140 parts of fly ash, 220-910 parts of machine-made sand, 220-910 parts of recycled sand, 980-1000 parts of recycled coarse aggregate, 160-180 parts of water and 8-12 parts of a water reducing agent. The reclaimed sand is used for replacing machine-made sand, the influence of building solid waste on the environment can be effectively reduced, CO2 emission is reduced, and resource recycling is promoted. Meanwhile, the preparation cost of the concrete is reduced, and the prepared concrete has relatively high strength, durability and interface transition area elasticity modulus, is excellent in performance and can meet the use requirements of actual engineering.
本发明属于建筑材料技术领域，公开了一种低碳高性能再生砂混凝土及其制备方法与应用，每立方米混凝土包括以下质量份的原材料：水泥300‑350份，粉煤灰120‑140份，机制砂220‑910份，再生砂220‑910份，再生粗骨料980‑1000份，水160‑180份和减水剂8‑12份。本发明利用再生砂取代机制砂，能够有效降低建筑固废对环境的影响，减少CO2排放量，促进资源循环利用。同时降低了混凝土制备成本，所制备的混凝土具有较高的强度、耐久性和较高的界面过渡区弹性模量，性能优异，能够满足实际工程的使用要求。
