Commercial concrete and preparation process thereof
The invention discloses commercial concrete and a preparation process thereof, belongs to the field of building materials, is used for building construction, and solves the problem that existing concrete cracks. The concrete is prepared from the following components in parts by weight: 300 parts of cement, 891 parts of mixed sand, 1005 parts of stones, 46 parts of mineral powder, 67 parts of fly ash and 7.6 parts of additives, wherein the additives comprise a polycarboxylate-type high-performance water reducing agent, polymethacrylic acid, polyethylene glycol, hair powder and modified shell powder. The polymethylacrylic acid enables the strength of the concrete to be rapidly increased under a low-temperature condition to obtain good strength; polyethylene glycol is used as a thickening agent, the hair powder can improve the adhesion of the concrete and can improve the toughness of the concrete.The shell powder takes natural shells as raw materials, has natural characteristics of natureand environmental protection, the main component is calcium carbonate, the shell powder plays a role of reinforcing ribs, and with reasonable matching of aggregate, powder, polymethacrylic acid, polyethylene glycol, hair powder and modified shell powder, the prepared commercial concrete has good anti-cracking performance.
本发明公开了一种商品混凝土及其制备工艺，属于建筑材料领域，用于建筑施工，解决了现有的混凝土会出现裂缝的问题，按重量百分比，包括如下组分：水泥300份，混合砂891份，石子1005份，矿粉46份，粉煤灰67份，外加剂7.6份，所述外加剂包括聚羧酸系高性能减水剂、聚甲基丙烯酸、聚乙二醇、毛发粉、改性贝壳粉。聚甲基丙烯酸使混凝土在低温条件下能迅速增加强度获得良好的强度，聚乙二醇是增稠剂，毛发粉能增加混泥土的粘附性，增加了混泥土的韧性，贝壳粉以天然贝壳作为原料，具有自然环保的自然特性，主要成分是碳酸钙，本身起加强筋作用，通过合理搭配骨料、粉料及聚甲基丙烯酸、聚乙二醇、毛发粉和改性贝壳粉，制备的商品混凝土具有良好的抗裂性能。
