Abstract: This paper illustrates the comparative study of direct shear transfer capacity in Normal Strength Concrete (NSC), SelfCompacting Concrete (SCC), High Strength Concrete (HSC) and Geo Polymer Concrete (GPC) using push-off specimens. Size of the mould used for the study was 150 × 150 × 260mm with two notches of 10mm thick placed perpendicular to axis of loading of specimen at 100mm apart opposite to each other. The line which joins the notch tips is known as shear plane for the study. Shear reinforcement across the shear plane was varied with number of bars (Zero, one, two and three respectively). A linear regression analysis was carried out and equation was developed toestimate the shear stresses and the theoretical results were compared with that of experimental data.
