        abstract = {A self – curing concrete is provided to absorb water from atmosphere to achieve better hydration of cement in concrete which solves the problem of lowered cement hydration because of improper curing and thus unsatisfactory properties of concrete. The present investigation involves the use of self – curing agent viz., polyethylene glycol (PEG) of molecular weight 6000 (PEG 6000) for dosages ranging between 0.5 to 2% by weight of cement added to mixing water. The experimental program was planned for a total of 120 cubes, 120 cylinders and 120 prisms were cast which involves different dosages (0%, 0.5%, 1% and 2%) of self-curing agent PEG-6000 for four different mixes (Mix 30 and mix 40), Under different curing conditions (indoor, conventional) with different aggregates (normal coarse aggregate and recycled coarse aggregate).Comparative studies were carried out for self-curing of recycled coarse aggregate and self-curing of normal coarse aggregate. Comparative studies were carried out for water retentivity , compressive strength, split tensile strength, flexural strength after 28 days for conventional cured and self-cured concrete. The properties of self – cured concrete are at least comparable and sometime better than those of concrete with traditional curing.  
         The experimental investigation shows that increase in SCA from 0% to 2% there is increase in strengths obtained. From concrete using normal coarse aggregate has shown a greater compressive strength, Flexural Strength, Splitting Tensile Strength compared to recycled coarse aggregate. And when compared to conventional curing there is a greater strength obtained for self-curing concrete.},
