Combined effects of ground granulated blast furnace slag and fly ash on the porosity and chloride penetration of sand concrete

This paper presents study results on the effects of ground granulated blast furnace slag (GGBFS) and fly ash (FA) on the mechanical properties, porosity and chloride penetration of sand concrete. Two series of concretes were prepared with W/B ratios of 0.36 and 0.32. The aggregate used consists of crushed sand with a modulus of fineness 3.2 and dune sand with a modulus of fineness 1.7. In each ser...
