Use of Mineral Admixtures and M-sand for Sustainable Concrete
The findings of an experimental programme to explore the properties of self-compacting concrete (SCC) containing dual admixtures are presented in this paper. Three different SCC mixes (grade-M25) were prepared using: (i) ordinary portland cement (OPC) and natural fine aggregate (NFA) (M-1); (ii) OPC, dual admixtures [fly ash (FA) + Metakaolin (MK)] and NFA (M-2); (iii) OPC, dual admixtures, NFA and manufactured sand (M-sand) (M-3). The properties of the various mixes are compared in both fresh and hardened states. The optimal level of OPC substitution by binary admixtures is 25% [FA(15%) + MK(10%)]. The NFA was partially replaced by M-sand after finding the optimal dose of binary admixture (FA + MK), and the optimum dose was 50%. All specimens were cured in tap water for 90 days and tested.
