Abstract

Concrete is the most important consumable in constructional construction, which is increasing. Cement is used as a constituent of concrete to produce it, and on the other hand it produces 8% of the world’s carbon dioxide produced. In this study, the mechanical properties and durability of concrete made with copper smelting slag, iron melt slag and metalaoleene as a substitute for cement have been investigated. A total of 384 samples were made up of 16 mixing designs with varying degrees of replacement of copper smelting slag, iron smelting, and metalaole waste. Mixing scheme According to the American ACI 211.1 regulations and the conditions for the SSD materials, dry aggregates then cement materials after that, and finally the supernatant, were gradually added to the mixture. On the designs in a fresh state, a slump test, and in a hardened condition at the age of 7, 14, 28, and 90 days, the compressive strength was tested according to standard BS 1881 and at 28 days of pressure test in accordance with DIN 1048-5. In all designs containing pozzolan, we see a decrease in water absorption compared to a pozzolan design. In, the constant percent displacement of water under pressure is related to the designs containing metalaole and the most related to the plans containing copper smelting slag.
