Three aggregate sizes 6-10mm, 10-20mm and 50% mix of both sizes are taken. Water-cement ratio of 0.30, 0.35 and 0.40 were used for each aggregate size. The objective of this investigation is to study the effect of variation in aggregate size Effect of Maximum Aggregate Size on the Bond Strength The bond between reinforcements and concrete is the only mechanism that transfers the tensile stresses from concrete to reinforcements. Several factors including chemical adhesion, roughness and reinforcement interface and bar bearing affect the bond strength of reinforcements with concrete. This work was carried out considering another varying factor which is maximum aggregate size.
