Abstract: In this study, the effect of a fly ash and a ground granulated blast-furnace slag on fresh properties, strength properties and pore structure was examined. In addition, the effect of the reduction of environmental impact of those admixtures was clarified.
From the test results, it can be concluded that (1) when the ground granulated blast-furnace slag and fly ash were used, the early strength of concrete decreased compared with concrete without the admixtures, (2) when the curing temperature of concrete is low, the rate of reduction in compressive strength of concrete is large compared with concrete without the admixtures, (3) the average pore size of concrete decreased compared with concrete without the admixtures and (4) the amount of CO2 emission per 1N/mm2 of concrete compressive strength decreased when the amount of fly ash and ground granulated blast-furnace slag increased.
