Clean production method of low-viscosity and high-strength concrete
The invention discloses a clean production method of low-viscosity and high-strength concrete, which comprises the step of: (1) selecting raw materials for concrete production and preparation. Each cubic meter of the high-strength concrete is from the following raw materials by weight: 340-360 kg of water, 460-480 kg of cement, 1600-1620 kg of fine aggregate, 2040-2060 kg of coarse aggregate, 90-110 kg of fly ash, 8-10 kg of an admixture and 100-120 kg of mineral powder. The coarse aggregate is cubic marble which is rough in surface, clean and free of dust, the marble is crushed until the particles are firm and have edges and corners, and the particle sizes are as follows: 11-15 mm (5%), 16-20 mm (10%), 21-25 mm (25%), 26-30 mm (30%), and 31-35 mm (30%). The method has the advantages that the small-particle-size marble plays a role in filling gaps among the large-particle-size marbles, the marble material in the concrete plays a role in bearing to the maximum extent, and the gaps among the marbles are reduced, so that the use amount of cement is reduced, the cost is saved, the production excess materials are effectively utilized, and the waste of raw materials is avoided.
本发明公开了一种低粘度高强混凝土的清洁生产方法，包括步骤(1)：选取混凝土生产制备的原料，配置每立方米高强混凝土包括以下重量原料：水340‑360kg、水泥460‑480kg、细骨料1600‑1620kg、粗骨料2040‑2060kg、粉煤灰90‑110kg、外加剂8‑10kg、矿粉100‑120kg；所述粗骨料为表面粗糙、干净无粉尘的立方体大理石，大理石为破碎处理至粒径坚实并带有棱角，粒径大小为：5％11‑15mm、10％16‑20mm、25％21‑25mm、30％26‑30％mm、30％31‑35mm。优点在于：使小粒径的大理石起到填充较大粒径的大理石之间的间隙的作用，使混凝土内的大理石料起到最大限度承重作用的，由于大理石之间的间隙变小，继而减少了水泥的使用量，节约了成本，且有效的利用生产余料，避免原材料的浪费。
