Abstract: The utilization of combination of different mineral admixtures like fly ash (FA), alcoffine (ALC) and nano silica (NS) which are by-products from industries possess pozzalanic nature and is an environmental friendly material in construction industry. The environmental impact can be minimized by making use of many industrial by products in a sustainable manner. The evaluation of strength and durability study was performed using on concrete with FA, ALC and NS as a partial replacement of Ordinary Portland Cement (OPC). The studied parameters were compressive strength, split tensile strength and flexural strength, as well as the durability study that involves water absorption and sorptivity. The combination of FA 25%, ALC 10% and NS 0, 0.5, 1, 2 and 3% was used in partial substitution of cement at by weight. The results show that among different NS content High performance concrete containing 25%-10%-1% FA-AL-NS exhibited the best results for the strength and durability property tests at 7, 28 days for strength and 28, 90 days for durability properties.
