USE OF SCBA & GGBS AS CEMENT REPLACEMENT IN CONCRETE
Manufacturing of every 1 ton of cement generates about 1.25 tons of CO2 gas. Thus, new engineering materials have become a necessity at present construction age because the cement industry impacts largely to global warming, greenhouse effects etc. Sugarcane bagasse ash (SCBA) and ground granulated blast-furnace slag (GGBS) are waste materials comprising pozzolanic properties but their disposal is causing acute environmental setbacks. This experimental work represents the results of substituting cement by SCBA and GGBS as supplementary cementitious materials in M40 grade concrete and detecting workability, compressive strength for 7, 28, and 56 days, tensile strength and bond strength for 28 days respectively on comparison with conventional concrete. Concrete specimens were prepared with 100% OPC and 30% replacement of cement by weight having proportions 5, 10, 15, 20, 25% for SCBA & GGBS. It was found that concrete with 15% SCBA and 15% GGBS indicated further improvement in the properties than all other mixes. The use of SCBA & GGBS advances the properties of concrete, set aside plenty of waste removal difficulties and diminishes cement rate rise and intensities of CO2 release by the cement production. Also these materials make the concrete more sustainable, light weight and low energy emitting.
