摘要

Recently, Nano particles have gain more attention in many fields to fabricate new materials with novel functions due to their unique physical and chemical properties. It has been found that physical properties of mortar, particularly strength and permeability significantly depend on its pore structure. Ultra-fine particles of Nano composites provide more homogenous distribution of hydrated products of concrete. This effect of micro and Nano particles enhances the durability of cement composites as well as the strength. In the present investigation, micro level materials such as marble powder (M.P) and Rice husk ash (RHA) are used to replacement of cement. Fine aggregate are replaced by Manufacturing Sand (M-Sand). In addition, influence of Nano particles on different properties of cement mortar was investigated with Marble powder and Rice Husk Ash as a well-known active pozzolana. Nano particles such as Al_2O_3 of different percentage (0.5%, 1%, 1.5% and 2%) by weight of cement were replaced and their influence on Mechanical properties, physical properties of the specimens were determined. The experimental results revealed that compressive strength and tensile strength were found to perform better than the control concrete.
