Effect of Dispersion Method for Nano-Materials on Some Mechanical Properties of Cement Mortar

Abstract

This study was involving the dispersion method ofnano-materials replacement and the interaction withcement mortar behavior for many mortar samples undervariable curing time ,with constant water to cement ratio(W/C=0.45) .Some mechanical properties such as(compressive, flexural strength and hardness tests) wasstudied. The main parameters are depending on the smallamount replacement ratio of nano-particle (ZrO2) withrespect to the mass of the cement (OPC) type (I). Theaddition of nano-material by replacement on the mixture ofmortar includes (1, 2, 3,4and 5%) with constant W/C ratioand also the amount of the fine aggregate use is 2.75 fromthe amount of cement. The results show that, the strengthof the mortar that consist from colloidal nano materialsgive better properties than from both mortar with dry nanomaterials replacement and without nano-materials in alltest, But the nano-Zirconia materials give good propertiesup to 2% in all tests compared with control cement mortar.
