Experimental studies on durability properties of Sustainable and Eco-friendly materials of GGBS and Fly ash in reinforced cement concrete

Abstract

This paper represents the use of supplementary cementitious material (SCM) with the blend of Portland cement in producing the corrosion resistive concrete. Fly ash and GGBS are partially replaced in three different ratios by the weight of cement. Compressive strength, chloride penetration, corrosion, sorptivity of (FA-GGBS) were determined. The test revealed the confrontation by chloride ions through the infiltration of concrete improves substantially by replacement coal by-product Fly ash, GGBS, and improvement increase with increases in the replacement level. The corrosion resistance of SCM-Proportional Mixes was better than the Control mix concrete. Besides, test results indicated that reduction of permeability of chlorides ion as a reduction in porosity in the concrete, that associates with increases in the compressive strength. It significantly affects the durability of the Supplementary Cementitious Materials. On the same proportional mixes, we have gone with microstructural analysis of Scanning Electron Microscopy (SEM) and (EDX), X-Ray Diffraction and non-Destructive tests are following method. The work is suggested that the higher replacement of cement with SCM shows more satisfactory results in the durability properties of proportional grades of SCM.
