Abstract

Abstract: The current article reports on investigation of nano-alumina (NA) on the effect of durability and micro-structural properties of the cement mortar. For this purpose 1, 3 and 5 percent of NA by weight of cement was used to replace the initial quantity of cement in the mortar. Durability of the cement mortar was measured through Water Absorption (WA) and Electrical Resistivity (ER) tests. From the studies conducted, it was found that the addition of NA significantly increased the ER but showed only minor variations in the WA. The micro-structural analysis was conducted using Scanning Electron Microscope (SEM). It was observed that the micro-structural properties increased with the incorporation of NA. The so obtained results were compared with the results of the cement mortar without any inclusion of NA.
