The invention provides an environment-friendly concrete preparation technology, and relates to the technical field of concrete preparation, and the environment-friendly concrete comprises 35-45 parts of cement, 10-20 parts of coarse sand, 10-15 parts of a water reducing agent, 5-10 parts of a dispersant, 40-50 parts of water, 5-10 parts of gangue powder, 10-15 parts of slag stone, and 5-10 parts of recycled concrete debris. The gangue powder is added into the cement, so that substances with the size of middle particles exist between the cement and the coarse sand, the overall density of the prepared concrete is more uniform, the used materials are byproducts in mining operation, the use of chemical products is reduced, and the cost is reduced. The mixing of the recycled concrete chippings and the slag stone is to reduce the usage amount of the slag stone, increase the waste utilization amount and reduce the industrial cost, and the state and components of each component before mixing are strictly monitored and adjusted in the preparation process of the concrete, so that the quality of the mixed concrete is more controllable, and the quality error is reduced.
本发明提供环保型混凝土制备工艺，涉及混凝土制备技术领域，包括水泥35‑45份、粗砂10‑20份、减水剂10‑15份、分散剂5‑10份、水40‑50份、矸石粉5‑10份、渣石10‑15份、再生混凝土碎屑5‑10份。本发明通过在水泥中加入矸石粉，使得水泥与粗砂之间具备中间颗粒大小的物质，使得制备出的混凝土的整体密度更加均匀，且使用的材料也是采矿作业中的副产品，降低了化工产品的使用，而再生混凝土碎屑与渣石的混合则是减少渣石的使用量，增加废物利用的量，减少工业成本，并且在混凝土的制备过程中严格监测调整各组分在混合前的状态与成分，使得混合出的混凝土的质量更加可控，降低质量误差。
