The Effect of Different Curing Method and Water /Cement Ratios on Concrete Compressive Strength


At this paper, an experimental investigation was conducted to explore the effect of different curing methods and water cement ratios on compressive strength and density of normal weight concrete. The samples had been submitted to five different curing methods including: water curing (standard curing), air curing and three types of colored plastic bags curing including (Transparent, white and black bags). The effect of w/c ratio on compressive strength at different curing had been studied too. Test results shows that the curing by plastic bags gives accepted results compared with standard curing and better than air curing. For all kinds of referenced curing the increasing in w/c ratios decrease the compressive strength, and the density of concrete samples reduces at air and plastic bags curing compared with standard curing.
