The compressive strength of concrete is an important factor within the mechanical properties. In most building structures, concrete strength is used to resist compressive forces and support load action on buildings. Compressive strength could be one of the basic measurements to review the overall quality of concrete. Mindess et al. (2003) states that the water/cement (w/c) ratio has a great impact on the strength of concrete. The higher the a/c, the lower the compressive strength. The lower the W/C, the greater the compression
