Effects of Aggregate Size on Concrete Shear Strength

Article Preview

Abstract:

In view of the importance of the applicability of small-scale beam specimens in replicating the shear behaviour of prototype reinforced concrete structures, this study was conducted on beam specimens cast with micro-concrete having scaled aggregates (maximum sizes: 10mm, 5mm, and 2mm) to investigate whether the use of micro-concrete impose any reduction in their shear strength. The results indicate the maximum aggregate size (s) has negligible effects on concrete shear strength, and the micro-concrete beam specimens replicate the shear behaviour of normal concrete.
