Abstract

The main aim of this study consists of the influence of nano-particle on some mechanical properties of cement mortar with and without nano particles replacement mortar was experimentally studied. The nano-particle used in this study was nano-Titanium dioxide (nano-TiO2) with the particle size of 30nm.This study involves the mixing method of nano-materials addition and interventions with cement mortar behavior for many mortar samples under variable curing time with constant (W/C = 0.45). Some mechanical properties like (specific compressive strength, split tensile strength and water absorption tests) was studied. In this study the main parameters depend include the small amount replacement ratio of nano-particle (nano-TiO2) and dispersion methods with respect to the Ordinary Portland Cement (OPC) type (I). The percentage of nano-material replacement on the mixture of cement mortar includes (0, 0.5, 1.0, 1.5 and 3%) for nano-materials with constant W/C ratio and also the amount of the fine aggregate use 2.75 from the amount of cement. The results show that, the strength of the mortar consist 1% and 1.5% TiO2 nano-particles are desired than traditional mortar. The results show that, the strength of the mortar consists of with ultrasonic dispersion of colloidal nano materials give better properties than reference specimens in all test. But the Nano-Titanium dioxide - materials give good properties up to 1.5%.
