Abstract

In this review, we study the effect of H/D ratio of core diameter on concrete core strength. It has been shown that the compressive strength of cylinderical concrete specimen grows up as the height –to-diameter ratio decreases. In fact, the strength correction factors are responsible for evaluating this feature shown in ASTM C42 and BS1881 although we can not apply it to high-strength concrete over 40 MPa. For this purpose, concrete core specimens of 100 mm diameter were cut into different lengths with respect to the following height-to-diameter ratios 1.0,1.25, 1.5, 1.75 and 2.0. The results showed that strength reduces when L/D ratio rises. Also, for various strength classes, the correction coefficients of L/D are different.
