From early times upto present day construction field is facing lot of problems, one of them is based on water. Atleast one third of water is required for construction. Growing water scarcity is now one of the leading challenges for sustainable development. An estimate by a global consultancy states that one lakh square feet of construction consumes over nine thousand million litre of water. Curing plays a vital role in the development of concrete durability. To avoid this water scarcity problem, Self curing was initiated. Many researchers have tested in mechanical properties of self curing of concrete but we predominantly look for durability of self curing concrete with silica fumes incorporating with different chemical agents like Poly Ethylene Glycol 6000 (PEG 6000) and Sodium Polyacrylate to avoid shrinkage effect. The grade of cement used was M30. The self curing agent of Poly Ethylene Glycol 6000 and Sodium Polyacrylate for dosages ranging from 0.20%, 0.30% & 0.40% related to the weight of cement. Partial replacement of cement with silica fumes with 5% and 10% to increase the properties of concrete. The ideal mix ratio was taken for casting of reinforced concrete beam and to analysis the strength and durability properties were captured with self curing concrete and conventional concrete.
