Production method of high-crack-resistance concrete
The invention discloses a high-crack-resistance concrete production method which comprises the following steps: (a) checking and screening concrete raw materials which comprise cement, water, coarse aggregate, fine aggregate, mineral admixture, admixture and slag, the water is weakly alkaline water, the coarse aggregate is stones with irregular shapes, the fine aggregate is river sand, the mineral admixture is mineral admixture, the admixture is mineral admixture, the admixture is mineral admixture, the slag is mineral admixture, and the admixture is mineral admixture; the mineral admixture is fly ash, and the additives are an expanding agent, a water reducing agent and a retarder. The proportion of water, cement and fine aggregate is 1: 3: 0.65, the concrete, the water, the cement and the fine aggregate are mixed to form cement paste, then coarse aggregate is placed in the cement paste, the cement paste wraps the surface of the coarse aggregate and fills the gaps of the aggregate, the concrete is supported, the gaps of large particles are filled with small-particle aggregate, and therefore the concrete is supported. The slag is added into the cement paste, the mineral admixture and the additive are added into the cement paste, and the concrete is formed by mixing, so that the production efficiency of the concrete is improved.
本发明公开了一种高抗裂混凝土生产方法，包括以下步骤：(a)检查筛选出混凝土原材料，所述混凝土原材料包括水泥、水、粗骨料、细骨料、矿物掺合料、外加剂、矿渣，所述水为弱碱水，所述粗骨料为形状不规则石子，所述细骨料为河砂，所述矿物掺合料为粉煤灰，所述外加剂为膨胀剂、减水剂和缓凝剂。本发明通过取用水、水泥和细骨料的比例为1：3：0.65，且通过将混凝土、水、水泥和细骨料混合形成水泥浆，再将粗骨料放入水泥浆内部，将水泥浆包裹在粗骨料的表面并填充在骨料空隙中，对混凝土起支撑作用，其中小颗粒的骨料填充大颗粒的空隙，将矿渣加入水泥浆中，并将矿物掺合料、外加剂加入水泥浆内部，混合形成混凝土，提高了混凝土的生产效率。
