Concrete production process based on carbon neutralization
The invention discloses a concrete production process based on carbon neutralization, and particularly relates to the technical field of concrete production, the concrete production process comprises the following raw materials (by weight): 50-85 parts of industrial waste residue, 25-30 parts of lime, 20-45 parts of aggregate, 30-50 parts of water, 30-70 parts of sand, 35-40 parts of cement, 10-20 parts of an air entraining agent, 10-25 parts of a water reducer, 30-65 parts of gypsum, 10-20 parts of a retarder, and 15-20 parts of an early strength agent. And 12-14 parts of a corrosion inhibitor. The prepared concrete is high in production efficiency and low in production energy consumption, the raw material source of the concrete is expanded, the strength of the concrete is obviously improved, the flowability of a concrete mixture is improved under the condition that water, the water cement ratio and the strength are not changed, the water consumption of the mixture can be reduced under the condition that the flowability and the cement consumption are not changed, and the production cost is reduced. The water reducing agent is added, so that the cohesiveness and the water-retaining property of the concrete can be improved, and the compactness of the hardened concrete can be improved.
本发明公开了一种基于碳中和的混凝土生产工艺，具体涉及混凝土生产技术领域，所使用原料(按重量份计)包括工业废渣50‑85份，石灰25‑30份，集料20‑45份，水30‑50份，砂子30‑70份，水泥35‑40份，引气剂10‑20份，减水剂10‑25份，石膏30‑65份，缓凝剂10‑20份，早强剂15‑20份，阻锈剂12‑14份。本发明通过，制备出的混凝土生产效率高、生产能耗低，且拓展了混凝土的原料来源，混凝土的强度得到明显的提高，在水、水灰比、强度均不变的条件下，增加混凝土拌合物的流动性，在保持流动性及水泥用量不变的条件下，可减少拌合物用水量，使水灰比下降，从而提高混凝土的强度，掺加减水剂可以改善混凝土的粘聚性、保水性，提高硬化混凝土的密实度。
