The self compacting self curing concrete gives the advantage of reducing water usage and compaction of concrete without compromising quality of concrete. Present work deals the strength and durability characteristics self compacting self curing concrete using natural and chemical admixtures. The Portland pozzolana (Fly ash based) cement, Silica fume, Metakaoline, Polycarboxylate Ether as chemical admixture, Poly Ethylene Glycol4000 (PEG4000) as self curing compound is used for this project. The mineral admixtures Silica fume, Metakaoline and combination of silica fume, Metakaoline at 5%,10%,15%,20% are replaced with cement,0.5 %,1.0%,1.5% Polyethylene Glycol 4000(PEG4000) as self curing agent is used at each mix. The compressive strength at various ages, Split Tensile strength at 28 days computed. The durability tests like acid attack, Chloride attack and sulphate attack test as per the standard was performed.
