Compound ash-doped concrete and preparation method thereof
The invention relates to the technical field of sulfur-fixing ash recycling, and discloses compound ash-doped concrete and a preparation method thereof. The composite ash-doped concrete is prepared from the following raw materials in parts by weight: 80-100 parts of ordinary Portland cement, 50-70 parts of converter steel slag powder, 20-30 parts of composite ash, 130-150 parts of sandstone, 10-20parts of a polycarboxylate superplasticizer and a polycarboxylate slump retaining agent and water, wherein the weight ratio of the sulfur-fixing ash to the finely ground sulfur-fixing slag is 0.4-1:1; and the weight ratio of the polycarboxylate superplasticizer to the polycarboxylate slump retaining agent is 1: 0.5-1. According to the invention, the concrete is prepared by replacing fly ash withthe compound doped ash of the sulfur-fixing ash and the finely ground sulfur-fixing slag, so that not only is the pollution of solid waste emission to the environment greatly reduced, but also the prepared concrete has relatively strong compressive strength.
本发明涉及固硫灰渣再利用技术领域，公开了一种复掺灰混凝土及其制备方法。所述复掺灰混凝土的原料包括普通硅酸盐水泥、转炉钢渣粉、复掺灰、砂石、聚羧酸减水剂、聚羧酸保坍剂和水，所述普通硅酸盐水泥为80‑100重量份，所述转炉钢渣粉为50‑70重量份，所述复掺灰为20‑30重量份，所述砂石为130‑150重量份，所述聚羧酸减水剂和所述聚羧酸保坍剂为10‑20重量份；所述固硫灰与所述磨细固硫渣的重量比为0.4‑1:1；所述聚羧酸减水剂与聚羧酸保坍剂的重量比为1:0.5‑1。本发明以固硫灰和磨细固硫渣的复掺灰代替粉煤灰制备混凝土，不仅极大降低了固废排放对环境造成的污染，而且制备的混凝土具有较强的抗压强度。
