Preparation process of high-strength premixed concrete
The invention discloses a high-strength premixed concrete preparation process, relates to the technical field of concrete preparation processes, and aims to solve the problems that most of existing high-strength premixed concrete preparation processes only add powder to improve the strength of concrete, so that a concrete structure has a certain anti-seismic effect, expansion of microcracks in the concrete cannot be hindered, and the strength of the concrete cannot be improved. In order to solve the problems of relatively single function and unsatisfactory use effect in the prior art, the invention provides the following scheme: the concrete comprises the following raw materials in parts by weight: 450-600 parts of water, 1000-1200 parts of cement, 1700-1850 parts of river sand, 3500-3700 parts of broken pebbles, 120-160 parts of coal powder, 8-14 parts of slag, 15-30 parts of silicon powder, 2-6 parts of a water reducing agent, 14-18 parts of steel fibers, 6-12 parts of alkali-resistant glass fibers and 0.1-0.5 part of a retarder. The concrete is reasonable in design, the steel fibers and the glass fibers are added into the concrete, the strength and shock resistance of the concrete are improved, expansion of cracks in the concrete can be hindered in the long-time using process, potential safety hazards are eliminated, and the using effect is good.
本发明公开了一种高强度预拌混凝土制备工艺，涉及混凝土制备工艺技术领域，针对现有的高强度预拌混凝土制备工艺，大多仅添加粉料提高混凝土的强度，使混凝土结构具有一定的抗震效果，无法阻碍混凝土内部微裂纹的扩张，功能性较为单一，使用效果不够理想的问题，现提出如下方案，包括以下重量份原料：水450‑600份、水泥1000‑1200份、河砂1700‑1850份、碎卵石3500‑3700份、煤炭粉120‑160份、矿渣8‑14份、硅粉15‑30份、减水剂2‑6份、钢纤维14‑18份、耐碱玻璃纤维6‑12份与缓凝剂0.1‑0.5份。本发明设计合理，在混凝土内添加钢纤维与玻璃纤维，不仅提高了混凝土的强度与抗震性，还可以在长时间的使用过程中阻碍混凝土内部裂纹的扩张，消除了安全隐患，使用效果好。
