Abstract: Nowadays, the application of Nano materials has received great attentions to improve the conventional concrete properties. The ordinary/normal concrete has low tensile strength, so it was supplied with steel rebars in order to improve the tensile strength of the structural concrete. It was found that partial substitution of cement by pozzolanic materials enhance concrete steel bond strength. Nano-clay is one of the pozzolanic material which researchers have focused on investigating its effect on cement mortar and concrete recently.
