  • What is the effect of coarse aggregate size in compressive ...

    The shape and size of aggregate have a significant impact on compressive strength of concrete. Larger the aggregate, greater is the tendency of blocking the bleed water and thus weaker is the transition zone (higher w/c ratio in area around the aggregate). This results in concrete cracking through the tra
