EFFECT OF COPPER SLAG AND FLY ASH ON MECHANICAL PROPERTIES OF CONCRETE

The tentative examination was operated to study the impact of using fly ash with cement and copper slag with fine aggregate on the character of concrete. Different concrete samples prefabricated with various quantities of copper slag vary up to 0% to 60% as fine aggregates substitution and 20% as fly ash replacement with cement. Concrete samples were determined for various strengths that is compressive, tensile and flexural strength and also. evaluated for Ultrasonic pulse velocity. The outcomes acquired for concrete declared that all samples with various copper slag quantities and constant fly ash proportion that is higher compressive strength as compare to the control specimen. The outcomes acquired for concrete show that the percentage(%) of copper slag increased then also increased the workability of concrete as compared with control specimens. If, copper slag more than 30% replacement with fine aggregate then the outcomes show the reduction of strengths because the water absorption of copper slag is very less. And these results shows that is 20% as fly ash substitution with cement and up to 30% as copper slag substitution with fine aggregate to acquired a good mechanical properties of concrete
