This paper presents an investigation into the engineering properties of alkali activated slag concrete (AASC) made with ground granulated blast furnace slag (GGBS) as sole binder. Four mixes of AASC were prepared using different Alkaline to GGBS ratios (0.4 and 0.5), Na2SiO3 to NaOH ratios (2.33 and 1.0) with concentration of NaOH solution as 12M and 16M.Specimens were cast and cured under ambient and heat curing(24 h at 60?C) conditions after undisturbed for 24 h in moulds at room temperature. Their performance was discussed and compared with conventional concrete (M20) produced using ordinary Portland cement. Engineering properties like compressive strength, flexural strength, splitting tensile strength and stress strain behaviour were evaluated as part of this study. The test results show that S-0.4-2.33-16M mix is better in compressive and splitting tensile strengths whereas S-0.5-2.33-16M mix exhibited higher flexural strength and S-0.5-1.0-12M mix has the highest toughness index.
