 Abstract
In this study, for improving of concrete properties, those are used ground granulated blast slag(GGBS) and fly ash(FA). There are some advantage to add the GGBS and FA in plain concrete. The objective of this study is to find the characteristics of fresh and hardened antiwashout underwater concrete which is followed by blended ratio of GGBS and FA. Experimental parameters were chosen that W/C was , S/a was and as the blended ratio of GGBS was set at 0, 10, 20, 30, 40, 50, and FA was set at 0, 10, 15, 20, 25, 30, in order to prove the properties of antiwashout underwater concrete can be changed by blended ratio of GGBS md FA. It was measured pH, suspension and slump flow of fresh antiwashout underwater concrete and compressive strength of hardened antiwashout underwater concrete in age of 7 days, 28 days and 56 days. The experimental results of fresh concrete show that pH, suspension and slump flow were all satisfied with KSCE (Korea Society of Civil Engineering) standard value and mix design standard value. To synthetically consider, the optimum blended ratio is about of GGBS and FA.
