Production method of high-crack-resistance concrete
The invention discloses a production method of high-crack-resistance concrete. The concrete is prepared from cement, water, aggregate, sand, fiber and additives, Portland cement is adopted as the cement, stone with irregular shapes is adopted as the coarse aggregate, river sand is adopted as the fine aggregate, polypropylene fiber is adopted as the fiber, and a retarder and a thickener are adopted as the additives; the cement is Portland cement, the use amount of the cement is 20-25% of the total mass of the concrete, the coarse aggregate is 10-20 mm broken stones, the use amount of the coarse aggregate is 20-30% of the total mass of the concrete, the sand is spun yarns, the use amount of the sand is 40-50% of the total mass of the concrete, the water is underground water, and the use amount of the water is 20-25% of the total mass of the concrete. The fibers are polypropylene fibers, the use amount of the fibers is 0.5%-1% of the total mass of the concrete, and the use amount of the additive is 0.5%-0.8% of the total mass of the concrete. A part of concrete is taken to form a concrete block, and the crack resistance strength and high and low temperature resistance of the concrete are detected through detection equipment, so that the crack resistance of the concrete is better.
本发明公开了一种高抗裂混凝土生产方法，所述混凝土原材料包括水泥、水、骨料、砂、纤维、外加剂，所述水泥采用硅酸盐水泥，所述粗骨料为形状不规则石子，所述细骨料为河砂，所述纤维采用聚丙烯纤维，所述外加剂为缓凝剂和增稠剂；所述水泥为硅酸盐水泥，水泥用量为混凝土总质量的20％‑25％，所述所述粗骨料选用10mm‑20mm的碎石，粗骨料用量为混凝土总质量的20％‑30％，所述砂采用细纱，砂用量为混凝土总质量的40％‑50％，所述水为地下水，水用量为混凝土总质量的20％‑25％，所述纤维采用聚丙烯纤维，纤维用量为混凝土总质量的0.5％‑1％，所述外加剂的用量为混凝土总质量的0.5％‑0.8％。通过取部分混凝土形成混凝土块，通过检测设备对混凝土的抗裂性强度和耐高低温进行检测，使混凝土的抗裂性更好。
