Auxiliary cementing material for concrete as well as preparation method and application of auxiliary cementing material
The invention provides an auxiliary cementing material for concrete as well as a preparation method and application thereof, and the auxiliary cementing material comprises the following components in parts by weight: 25-40 parts of modified converter steel slag, 30-40 parts of high titanium slag, 15-30 parts of modified waste red brick powder, 10-20 parts of desulfurized gypsum and 0.05-0.1 part of a grinding aid, the modified converter steel slag comprises the following raw materials: converter steel slag powder, lithium slag powder, calcium silicon slag powder and waste red brick powder in a mass ratio of (5.5-7.5): (2-2.5): (1.8-2.4): 1; the modified waste red brick powder comprises the following raw materials: waste red brick powder, mixing plant waste slurry and Ca (OH) 2 in a mass ratio of (8-10): (2.2-3.5): 1.5. According to the auxiliary cementing material disclosed by the invention, due to the matching of all the components, the activity of the auxiliary cementing material is improved, the auxiliary cementing material can play a synergistic and complementary role after being applied to concrete, the early strength of the concrete is improved, the saltpetering phenomenon is reduced, and the flowability is improved.
本发明提供了一种用于混凝土的辅助胶凝材料及其制备方法和应用,包括如下重量份的组分:改性转炉钢渣25~40份、高钛矿渣30~40份、改性废弃红砖粉15~30份、脱硫石膏10~20份和助磨剂0.05~0.1份,改性转炉钢渣的原料包括质量比为(5.5~7.5):(2~2.5):(1.8~2.4):1的转炉钢渣粉、锂渣粉、钙硅渣粉和废弃红砖粉;改性废弃红砖粉的原料包括质量比为(8~10):(2.2~3.5):1.5的废弃红砖粉、搅拌站废浆水和Ca(OH)2。本发明中的辅助胶凝材料由于各组分的配合,提搞了其活性,应用于混凝土后能起到协同互补的作用,提高混凝土的早期强度、减少泛碱现象,改善其流动性。
