| Abstract: | This paper presents a laboratory study on the strength development of concrete(GGFAC)containing combinations of fly ash (FA) and ground granulated blast furnace slag (GGBS) in different curing conditions.For contrast,the strength development of control portland cement concrete(PCC) and high-volume fly ash high-strength concrete(HFAC) was also studied.The microstructure of different concretes at the age of 7 days was also studied by using electron microscopy(SEM).In this paper,the mechanisms of the effect of different pozzolanic materials on the strength development of concrete was also pilot studied. |

| Keywords: | high-strength concrete pozzolanic materials strength-development |
