Effect of GGBFS on time dependent compressive strength of concrete
AbstractThis paper addresses the compressive strength properties when GGBFS is used to make concrete and discuss in detail the compressive strength development of concrete cubes and cylinders. The uniaxial compression tests have been conducted on these concrete specimens with and without GGBFS at the ages of 3, 7, 28, 56, 90, 150 and 180days. Experimental values show increasing concrete strength with GGBFS up to 40% but at a higher period of maturity (56days and more). Sixty percent GGBFS blending, however, shows reduced strength when compared to 40% blending. A comparative study has also been carried out between the experimentally obtained compressive strength and strength predicted by the models given in SP-24 (Indian Standard), ACI-209, CEB-FIP and GL-2000. Based on the experimentally obtained results a strength predicting models has also been proposed for GGBFS based concrete.
