In today's world, there is a huge demand for infrastructure in less space and with high altitudes. For such heavy structures, the space between the reinforcing bars is very less. To overcome these problems High Strength Self Compacting Fiber Reinforced Concrete (HSSCFRC) is developed. To pump concrete for higher altitudes and compact itself, SCC properties are used. To build heavy structures in less space high strength is required. So that M grade of concrete are 100 being developed in India. The finer filler particles like micro silica and quartz powder increase the strength. Quartz in crystalline form is an inert material, but in amorphous form the silica reacts with the calcium hydroxide (which is the waste product) to form gel. The gel formed holds the aggregate and therefore a good bond is formed. This paper presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate was replaced with Quartz Sand. Quartz Sand was replaced in six percentages i.e. 0%, 20%, 40%, 60%, 80% and 100% of fine aggregate by weight. Tests were performed for properties of fresh and hardened concrete. Compressive strength, splitting tensile strength and flexural strength were determined at 7, 28 and 90 days. Test results indicate significant improvement in the strength properties of high strength self compacting concrete by the inclusion of Quartz Sand as complete replacement of fine aggregate and can be effectively used in structural concrete.
