Abstract
Experimental program designed to study the effect of Nano silica, glass fiber, and carbon fiber on compressive strength and shear strength of concrete. The program consists of 19 push-off shear specimens, and 21 cubes were cast. In this study all specimens were grouped into three series with different percentage of added materials.The results had shown improvement in compressive strength with the addition of three materials while shear strength improved with the addition of carbon fiber
