THE EFFECT OF CURING METHODS ON COMPRESSIVE STRENGTH AND DURABILITY OF CONCRETE

This research work aimed at studyingfeasibility of using external and internal curing compounds in local conditions. Various curing methods selected for this comparative study are immersion, sprinkling, membrane curing by two different brands of external curing compounds and internal curing by two different compounds. The performance parameters chosen for this evaluation are 7, 28 and 56 days compressive strength, durability and economical analysis for each curing method and appropriate rating procedure is done (Rating evaluation is done with use of interpolation technique). Durability achieved by each curing method, under consideration, is evaluated on basis of percentage water absorbed by concrete block cured by that method. Economical analysis is done by considering different cost such as water charges, labour charges, electrical energy cost, cost of curing compounds related to various curing method.
