Influence of Hybrid Nano-Particles on Properties of Cement Mortar

Abstract

Development of voids is one among the important properties that deprive the strength and durability of cement concrete. Voids not only been developed between heterogeneous ingredients of concrete but as well among the homogenous ingredients due to improper compaction and poor quality of materials etc. In this study, an attempt has been taken to study the effect of reduction in voids among the homogenous materials on strength properties of cement mortar. To counteract formation of voids, a Nano-material (Ceric Ammonium Nitrate H8N8CeO18) is being loaded over another Nano-material (Silica SiO2) each having different properties to act as a single Hybrid Nanomaterial (HN). Pore volume analysis, Infra-red test, and SEM analysis were performed to study the properties of HN. On the other hand, various tests like setting time, compressive strength and split tensile strength were performed on cement mortar specimens upon addition of HN by 3%, 5%, 7%and 10% by weight of cement. Results reveal that strength of mortar with HN is higher compared to mortar with Nano silica as well as conventional cement mortar specimens.
