  • Compressive Strength test on brick and its importance

    Compressive Strength test on brick and its importance

    2020-5-10Compressive Strength of Bricks Compressive strength of bricks is the capacity of brick to resist or withstand under compression when tested on Compressive testing machine CTM. The Compressive strength of a material is determined by the ability of the material to resist failure in the form of cracks and fissure.

    By reviewing the literature, it is concluded that an efficient approach to predict the compressive strength should be taken into account, while there are some models. Hence, the main purpose of this study is to propose an efficient approach to predict the compressive strength of concrete using non-destructive tests UPV and RN. 2.
