Abstract
Possible usage of nano oxides such as nano SiO2, nano ZrO2, nano Al2O3, nano Fe2O3 and nano TiO2 for improving the mechanical properties of concrete has been explored in the present study. Action mechanisms proposed by various researchers for the enhancement of structural arrangement of cement at nano level by incorporating different oxides are discussed. It is observed that the reported studies on usage of nano oxides for construction material are scanty and scattered; and the findings are non convergent. To understand the structural configuration of the oxides at nano level, TEM and XRD studies on the oxides are carried out. In the present study, it is found that the mechanism behind the function of nano materials yet to be explored in detail, in order to gain the full effect of nano materials as intended. Enabling Form-Structure-Function properties of nano materials with cementitious materials can provide an excellent idea to use them in an effective way. Finally, it is concluded that to exploit the huge potentiality, a concerted effort from both science and engineering is required to engineer the available cement at nano level and develop smart cementitious building materials.
