Abstract
The experimental study of two supplementary cementitious material on self-compacting concrete was investigated. Three mixes were designed, the control mix without the supplementary cementitious material, second mix with metakaolin (MK) and third mix with ground granulated blast furnace slag (GGBFS) both at 5, 10, 15, 20 and 25% respectively. After each mix preparation, workability test was carried out and specimens of the three mixes were cast and cured in water for 7, 14, 21 and 28 days respectively. Tests on hardened concrete were carried out to know the compressive strength of the three-mix designs. The test results showed that a replacement of 5% of both admixtures GGBFS and Mk increased in the compressive strength compared to the control mix. Also observed was the presence of mineral admixtures that had a significant on the strength loss due to the sodium, calcium and magnesium sulphate attack. The best resistance was obtained for 5% MK and GGBFS at 28 days curing.
