Abstract:

In this experimental work, the effect of Self-Curing polymer Polyethylene Glycol 400 (PEG 400) on various physical properties of Ordinary Portland Cement (OPC) of 53 grade such as standard consistency, initial setting time (IST), final setting time (FST), soundness and compressive strengths at 3, 7 and 28 days were investigated using the guidelines given in Indian Standard codes. The average molecular mass of Self-Curing polymer is 400. It was added to OPC with the rates of 1%, 1.5%, and 2% by dry cement mass. Totally, four mixes were produced; one conventional or reference mix and the remaining three with different PEG 400 contents. The outcomes of experimental work led to the findings that incorporation of PEG 400 in OPC did not significantly affect the standard consistency value. However, with the increased dosages of Self-Curing liquid, IST and FST were prolonged. The soundness of Self-Curing polymer-mixed cement paste was better than that of the reference mix, the better soundness property being for the addition of 1.5% of PEG 400. Compressive strength values of PEG 400- modified standard cement-sand mortar cubes kept in the open air in the laboratory for Self-Curing were on par with that of reference cubes immersed underwater.
