Concrete plays major role in the
I. INTRODUCTION:
construction industry and with rapid increase of urbanisation utilization of concrete is increasing at a rapid phase and
Due to continuous usage of naturally available
precious natural resources are depleting and also production

the generation of electricity world is more dependent on
generations. Hence there is a necessity for preparing

Shear strength is a property of major significance and various attempts have been made to develop MODE-II (Sliding shear) test specimen geometries for investigating the shear type of failures. Out of these the best suited is suggested as Double Centred notch (DCN) specimen proposed by Sri Prakash Desai and Sri Bhaskar Desai.
II. REVIEW OF LITERATURE: A brief review of available studies related to the present strength properties of cementitious materials is presented According to Clarke, J.L (1) Tensile strength of
