Core Sampling and Testing of Concrete and Factors ...

Fig: Concrete Core. The strength of a concrete core test specimen depends on its shape, proportions and size. The influence of height/diameter (H/D) ratio on the recorded strength of cylinder is an established fact. Strength of core have to be related to the standard cylinder strengths, i.e. for H/D ratio of 2. Thus core should be preferably have this ration near to 2. For values of H/D less ...
