This paper presents a laboratory study and comparison on mechanical properties of cement mortar with nano silica and silica fume . The results were compared with those of control Portland cement concrete (OPC) . These included compressive strength and Flexural Strength . after 3 , 28 and 90 days.
The Result Shown in same mass of additive material , the mechanical properties of OPC sam-ples as expected raise by time but finally gain lowest score, e.g. at 90 days the compressive strength sample that contain 10% nano silica have more 70% performance by OPC .
Furthermore samples that contain nano silica have better behavior as silica fume until 28 days , e.g. the sample that contain 7.5% nano silica have 50% better performance as sample that contain same micro silica . after 28 days the samples that contain micro silica shown higher value e.g. at the compressive strength of mortar cement 7.5% micro silica at 90 days earned 40% more score as sample that contain same mass of nano silica .
The samples that contain micro silica and nano silica simultaneously have behavior between result of samples that contain micro silica and the samples that contain nano silica.
