Experimental Study on Mechanical Properties of Hardened Concrete using Cupola Slag as Partial Replacement of Cement and Coarse Aggregate

Abstract

The simplest way of getting aggregate is from naturally available sources. Excavation of rocks from valley which is generally produces worst environmental impacts. Cutting and screening out of coarse aggregate makes the conventional concrete more costly and scarce due to small sized limited quantity of natural materials which is used. Cupola slag can be use in construction industry as replacement of coarse aggregate and cement. Cupola slag is replaced with coarse aggregate and cement with optimum percentage of replacement to check the suitability of concrete to Mechanical properties, Durability, Workability and Environmental feasibility.

Even only Coarse aggregate can not fulfill the requirements of constructions so there is a need to search a replacing material cupola slag in this study efforts are made to replace the natural aggregate with cupola slag aggregates in varying percentage of replacement from 0 to 100 percent for intervals of 20  percent for M25 grade concrete with 0.4 constant W/C ratio under accelerated concrete curing condition for 7 & 28  days are made to carry out impact on compressive strength, split tensile tests and flexural strength of concrete.
