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).
parameters which were investigated for recycled aggregate concrete and compared with natural aggregate concrete as per BIS specifications found to be decreasing gradually as the percentage of recycled aggregate are increased. Key Words: Recycled aggregate, workability, compression strength, indirect tensile strength, flexural strength, modulus

The ultimate strength of concrete is related to water/cement ratio and the size, shape, and strength of the aggregate used. Concrete with lower water/cement ratio (down to ) makes a stronger concrete than a higher ratio. Concrete made with smooth pebbles is weaker than that made with roughsurfaced broken rock pieces for example.
Abstract: The purpose of this paper is to investigate the strength parameters of concrete manufactured using natural and recycled Guanapo coarse and fine aggregates and to determine by analysis any correlations between their compressive strength and splitting tensile strength testing as conducted according to ASTM C39 and ASTM C496 respectively.
