UTILIZATION OF COPPER SLAG AS A PARTIAL IJIRAE

Key words: copper slag, FA= fly ash, sand replacement, compression, flexure, split tensile. I. INTRODUCTION Concrete is the world's most ancient, capable, durable and reliable construction material. After water, concrete is the most used material, which required large quantities of fine aggregate. As there is great demand of aggregates mainly

CIP 25 Corrosion of Steel in Concrete

Increased corrosion resistance can also come about by the use of concrete additives. Silica fume, fly ash, and blast-furnace slag reduce the permeability of the concrete to the penetration of chloride ions. Corrosion inhibitors, such as calcium nitrite, act to prevent corrosion in the presence of chloride ions.

Corrosion and Leaching Studies in Blended Copper Slag Mortar

Copper slag usually has a low content of CaO; granulated copper slag exhibits pozzolanic properties as CaO content in copper slag increases, it can exhibit cementitious properties. Studies [8-12] indicated that a copper slag, which contains approximately 19% CaO, show a good cementitious property under the activation of NaOH.
