Abstract |
Recently, the amount of the mineral admixture including fly ash and ground granulated blast-furnace slag was increased for the purpose of CO2 gas emission reduction in the concrete industry. However, in the case of korea, estimation model of strength development in concrete structural design code was prescribed a constant value according to cement type and curing method about the portland cement. therefore, the properties of strength development according to time of concrete using fly ash and ground granulated blast-furnace slag does not reflected estimation model of strength development. Accordingly, this paper was evaluated strength according to time on the concrete strength range using fly ash and ground granulated blast-furnace Slag and the strength development constant βsc of concrete according to the kind of the mineral admixture and mixing ratio was proposed.
