The strength of the bond between aggregate and cement paste depends upon the surface texture. An aggregate with rough and porous texture may increase the aggregate-cement bond up to 1.75 times, in which may increase the compressive and flexural strength of concrete up to 20%. The surface pores help in the development of good bond
