compressive strength of concrete and age graph Solutions Just Right For You

The curve in which compressive strength is plotted against age is generally of the form shown in the figure As can be seen enough strength has usually been attained by age 7 days to give some indication of whether the concrete is gaining strength at a satisfactory rate so 7 days is a useful age 8/26/2018Thank you Shekhar Saxena for A2A With time the concrete strength is increased this increase in strength compensates for some of the member strength due to reduction in the steel cross-section area One should not be satisfied with making a concr
