Indian Concrete Journal - ICJSummary: Concrete is the core material of construction that has industrially made of calcareous mixture-cement as one of its core component. The use of large quantities of cement produces increasing CO2 emission, and as a consequence the green- house effect. A method to reduce the cement content in concrete mixes is to use mineral admixtures of various kinds which yields the desired results with lesser cement content, there are various admixtures for high strength concrete one of which is nanosilica that has been obtained from olivine of industrially produced by synthesis, these commercially available nanosilica (10 to 50 nm) attains a saturated yield state and decreases in yield strength on further increase in concentration of nanosilica. This research work aims to check the concrete with nanosilica dosage that has any effect on various mechanical and durability properties when compared to conventional concrete. Concrete samples were casted with incrementally varying dosage of nanosilica using M40 grade of concrete as per Indian standard design and M60 grade of concrete as per American standards. Casted specimens were tested for compressive, splitting tensile strengths for a curing period of 7 days and 28 days, and durability properties such a water absorption and acid test for a varying curing periods.
