Effect on Quality of Cement Mortar by I nclusion of Nano Particle of Zinc Oxide

Abstract

Now days, there are so many new nano-technologies and methodologies are developed on the field of construction. These days, there is a swiftly rising concern especially using Nano-particles in Portland Pozzolana cement (PPC) concrete to improve the overall properties. The upper layer area of Nano-particles gives more chemical reaction at the subject to gives improved properties and capacities. Complete experiment the mixture of PPC- mortar with Nano-particles, ZnO with diameter of 50-60 nm of compressive-strength are investigated. ZnO have good physical and chemical properties such as dissolve in most of acids, reducing void ratio, availability in different crystalline forms gives enhanced mix of mortar. The principle reason for this investigation prepare a blended mortar with improved mechanical properties. The impacts of nano particles on the qualities such as compressive strength of mortar were experimentally investigated. The blended cement consists of Portland Pozzolana cement (PPC) and nano zinc oxide (NZnO) particles are used. The blended cement given in this investigation consists of Por PPC-cement and NZnO particles. The cement is moderately replaced with NZnO of 0, 0.5, 1, and 1.5 % by PPC cement. The mixture of cement, sand and water was prepared by the ratio of 1:2 and 1:3 of cement-sand by weight with water – binder ratio of 0.35. The strength of cement mortar will be measured after 7, 14 and 28 days. By adding NZnO, we can get good strength values of concrete more than usual strength values we got approximately 18%, of more strength by replacing 1.5% of cement by weight and also there is minimum usage of water with using super plasticizer.
