Premixed concrete production process
The invention discloses a premixed concrete production process, relates to the technical field of concrete production, and aims to solve the problems that the quality of premixed concrete used for a long time is different, the premixed concrete is easy to freeze when the air temperature is relatively low and the use effect is not ideal enough due to the fact that the control of each component is not accurate enough in the conventional premixed concrete production process. According to the scheme, the concrete is prepared from the following raw materials in parts by weight: 255-300 parts of water, 500-600 parts of cement, 905-1086 parts of fine aggregate, 1840-2208 parts of coarse aggregate, 15-32 parts of an early strength agent, 7.5-11 parts of a retarder, 15-36 parts of an air entraining agent, 50-70 parts of an expanding agent and 15-30 parts of an anti-freezing agent, and the ratio of the water to the cement to the fine aggregate to the coarse bone meal is 0.51: 1: 1.81: 3.68. According to the present invention, the design is reasonable, the control of each component is accurate, the quality of the premixed concrete is ensured, the premixed concrete cannot be frozen even at the low temperature, the construction efficiency is improved, the use effect is good, and the method is worthy of promotion and use.
本发明公开了一种预拌混凝土生产工艺，涉及混凝土生产技术领域，针对现有的预拌混凝土生产工艺，各成分的把控不够精确，导致预拌混凝土长时间使用质量不一，在气温较低时预拌混凝土易被冻结，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255‑300份、水泥500‑600份、细骨料905‑1086份、粗骨料1840‑2208份、早强剂15‑32份、缓凝剂7.5‑11份、引气剂15‑36份、膨胀剂50‑70份、防冻剂15‑30份，其中水、水泥、细骨料、粗骨粉的比例为0.51：1：1.81：3.68。本发明设计合理，各成分的把控较为精确，保证了预拌混凝土的质量，即使在温度较低时也不会被冻结，提高了施工效率，使用效果好，值得推广使用。
