Heavyweight concrete

The invention relates to heavyweight concrete, technically characterized be being made from 130-135 parts of cement, 880-885 parts of sand, 495-500 parts of crushed stone, 615-620 parts of steel slag, 105-108 parts of fly ash, 90-93 parts of mineral powder, 5.2-6.0 parts of an admixture, and 170-180 parts of water, wherein the admixture is composed of a polycarboxylate superplasticizer, 3-nitrophthalimide and curcumin. The heavyweight concrete has the advantages that slump may reach 200 mm, the heavyweight concrete may be pumped for construction, segregation and layering rarely occur, and the heavyweight concrete has good solid density uniformity after formation. 本发明涉及种重混凝土，其技术要点是：以重量份数计，由以下原料组成：水泥130-135份，砂880-885份，碎石495-500份，钢渣615-620份，粉煤灰105-108份，矿粉90-93份，外加剂5.2-6.0份，水170-180份；其中，所述外加剂由聚羧酸减水剂、3-硝基邻苯二甲酰亚胺和姜黄素组成。其达到的技术效果是：坍落度可达到200mm，可进行泵送施工，而且不易产生离析、分层,重混凝土成型后实体密度均匀。
