N2  - In this study, the effect of silica fume (SF), and nano-silica (NS) addition to portland limestone cement (CEM II\B-L) on mechanical properties (compressive strength, and tensile strength), durability (Permeability, and Elevated temperature resistance). And comparable with ordinary portland cement (CEM I). Pozzolanic materials added as a replacement of cement by 10% of silica fume (SF), and 3% of nano-silica (NS), as blended cement (PLC or OPC {u2013} SF), and ternary blended cement (PLC or OPC {u2013} SF -NS). Concrete cubes in which mix, were tested on compressive strength at 7, 28, 56 days, permeability, and elevated temperature resistance at 56 days. Concrete cylinders in which mix, were tested on splitting tensile strength at 56 days. The results of the compressive strength and permeability resistance of Portland limestone cement showed a competitive strength and permeability resistance comparable to ordinary Portland cement in a low w/c ratio
