Preparation method of slag powder concrete material
The invention relates to a preparation method of a slag powder concrete material. The preparation method comprises the following steps: A. preparing modified slag powder; B, weighing the following components in parts by weight: 10-20 parts of cement, 5-10 parts of modified slag powder, 0.2-0.5 part of an early strength additive, 5-10 parts of water and 30-40 parts of aggregate; and C. adding the cement, the modified slag powder, aggregate, the early strength additive and the water into a stirring device, and uniformly stirring and mixing to obtain the slag powder concrete material. According to the invention, the modified slag powder is adopted to replace about 35% of the total amount of a cementing material (cement) in a traditional prefabricated part concrete formula, so that the carbonemission can be greatly reduced; and in the raw materials, the main raw material of the slag powder concrete is industrial waste, the economic benefit is good, environmental pollution can be reduced,and the tension degree of cement is reduced.
本发明涉及一种矿渣粉混凝土材料制备方法，包括以下步骤：A、制备改性矿渣粉，B、称取以下按质量份数计的组分：水泥10‑20份，改性矿渣粉5‑10份，早强添加剂0.2‑0.5份，水5‑10份，骨料30‑40份。C、将水泥、改性矿渣粉、骨料、早强添加剂、水加至搅拌设备中，搅拌混合均匀得到矿渣粉混凝土材料。本发明采用改性矿渣粉能取代传统预制构件混凝土配方中胶凝材料(水泥)总量的35％左右，能大大减低碳排放；且原材料中,矿渣粉混凝土主要原材料系工业废料，经济效益良好，还可减轻环境污染，减轻水泥的紧张程度。
