Improved Properties of Antiwashout Underwater Concrete Containing Mineral Admixtures

This paper describes a study that was carried out in order to determine the application of fly ash (FA) and ground granulated blast furnace slag (SG) for the purpose of enhanced mechanical properties and chemical resistance of antiwashout under concrete (AWC). As a result of experiments, mechanical properties, suspended solids and pH value all satisfied “Standard Specification of Antiwashout Admixtures for Concrete” prescribed by the Korean Society of Civil Engineers (KSCE). Slump flow, efflux time and elevation of head were all improved with respect to the control of concrete. For the immersion test, x2 artificial seawater, 5% were used and at all test ages, compressive strength and mass variation were determined. At 91 days of immersion, XRD analysis was carried out in order to investigate the reactants between cement hydrates and chemical ions and some crystalline elements such as gypsum, ettringite and Fridel’s salt were found.
