Limestone superfine powder cement concrete and preparation method thereof
The invention relates to the field of cement concrete, and particularly discloses limestone superfine powder cement concrete and a preparation method thereof. Comprising the following raw materials in parts by weight: 1100-1200 parts of coarse aggregate, 550-650 parts of fine aggregate, 160-210 parts of cement, 4-7 parts of a water reducing agent, 100-140 parts of water, 140-160 parts of an admixture and 60-120 parts of a stabilizer, the admixture comprises ultrafine limestone powder, fly ash and mineral powder, the weight ratio of the ultrafine limestone powder to the fly ash to the mineral powder is 5: 3: 2, and the stabilizer comprises a loading agent, a binding agent and a reinforcing agent. The weight ratio of the loading agent to the binding agent to the reinforcing agent is 3: 1: 2. The cement concrete provided by the invention has the advantage that the adverse effect of the addition of the superfine limestone powder on the chloride ion diffusion resistance of the concrete is reduced.
本申请涉及水泥混凝土领域，具体公开了一种石灰石超细粉水泥混凝土及其制备方法。包括以下重量份的原料：粗集料1100～1200份，细集料550～650份，水泥160～210份，减水剂4～7份，水100～140份，掺合料140～160份，所述掺合料包括石灰石超细粉、粉煤灰和矿粉，所述石灰石超细粉、粉煤灰和矿粉三者重量之比为5:3:2，稳定剂60～120份，所述稳定剂包括负载剂、结合剂和增强剂，所述负载剂、结合剂和增强剂三者重量之比为3:1:2。本申请的水泥混凝土具有减少超细石灰石粉加入对混凝土抗氯离子扩散性能的不良影响优点。
