铜渣的特点是含铁高、容重大(1830公斤/立方米)、结晶致密,目前在铜冶炼厂堆积较多。我们针对能否利用铜渣的特点配制防射线重混凝土这一问题进行了试验工作,取得了初步成果。通过试验表明,铜渣石子的粒径5～10毫米和10～20毫米各为50％,铜渣砂和普通砂各为50％,效果较好。铜渣混凝土配合比 Copper slag is characterized by high iron content, large capacity (1830 kg/m3), and dense crystals, which are currently accumulated in copper smelters. We have carried out experimental work on the issue of whether we can use the characteristics of copper slag to prepare ray-proof heavy concrete, and achieved preliminary results. Through experiments, the particle size of copper slag is 5 to 10 mm and 10 to 20 mm each is 50%, copper slag sand and ordinary sand are 50% each, and the effect is good. Copper slag concrete mix ratio
