水淬铜渣代砂在建筑工程中的应用

Application of shrend copper ash as substitute of sand in architectural work

水淬铜渣是铜冶炼过程中产生的一种工业废渣,颗粒略粗于普通砂。把原状铜渣(自然级配的铜渣)加工成中、细砂,可在建筑工程中广泛应用。经多年的试验研究和工程实践证明,铜渣混凝土、铜渣砂浆、铜渣作砂垫层处理软弱地基等,都取得了良好的经济效益和社会效益。

Shrend copper ash is a kind of industrial waste out of smelting process of copper, with its grain slightly bigger than normal sand. Intact copper ash (or copper ash of natural grading) is widely applied in architectural works after it is processed into intermediate/fine sand. Results of many years of test and research as well as engineering practice demonstrate that applying copper ash concrete, copper ash sand slurry or copper ash as sand cushion to treat weak foundation renders good economic and social benefit.
