WebFeb 1, 1983 · In order to convert all core specimens to approximately the same strength basis as the standard 6x12-inch test cylinder, a correction factor is applied to the calculated strength. This factor, based on the ratio of length to diameter (l/d), has been given as 0.98 for l/d = 1.75, 0.96 for l/d = 1.50, 0.93 for l/d = 1.25 and 0.87 for l/d = 1.00. WebDec 27, 2016 · 4.1 Cast-in-place cylinder strength relates to the strength of concrete in the structure due to the similarity of curing conditions because the cylinder is cured within the slab. However, due to differences in moisture condition, degree of consolidation, specimen size, and length-diameter ratio, there is not a unique relationship between the strength of …
