Abstract: There are number of ways in which internal curing for concrete can be accomplished. One of the techniques of self curing is by using hydrophilic materials in concrete. The use of hydrophilic materials in concrete minimizes the loss of water and also attracts moisture from the atmosphere and help in continuous curing of concrete. Polyethylene Glycol, Paraffin Wax, Acrylic acid are some of the commonly available hydrophilic materials in market. This paper discusses the experimental investigation to arrive at the optimum dosage of Polyethylene Glycol (PEG) in concrete. The parameters in the study are two grades of concrete, PEG of two molecular weights, different dosages of PEG and two curing conditions. The variation of internal moisture and compressive strength was studied using standard concrete cubes of dimensions 150 mm x 150 mm x 150 mm. The variation of internal moisture was measured by weighing the cubes at regular intervals. It is found that, for low dosages of PEG the variation of weight and compressive strength was not significant when the concrete is cured by indoor curing and conventional curing.
