Extensive research work is in progress throughout the world in concrete technology to find alternative materials which can be partially or fully replace of Ordinary Portland Cement and which can also meet the required strength and durability, mainly aims at reducing cost and environmental effects due to cement manufacturing processes.. In the present study, Ordinary Portland Cement (OPC) of 43 grade is partially replaced by up to 30% of mineral admixtures such as, Fly Ash (FA), Ground

GI Fibre Reinforced Concrete with 0.5% and 1.0% GI-Fibre content by volume fraction are considered for study M30 grade of concrete with a constant Water-Cement ratio of 0.4 has been used in the work. The workability characteristics are studied through slump test. The strength characteristics of Ternary Blended GI Fibre Reinforced Concrete such as, compressive strength, split tensile strength and shear strength test are compared with Reference Mixes of 0.5% GI-FRC and 1.0% GI-FRC. In this work, a total of 135 specimen have been cast and tested at 28 days for Compressive Strength, Split Tensile Strength and Shear Strength. The Ternary Blended FRC with 20% Fly Ash and 10% Silica Fume replacement of cement has yielded maximum increase in Compressive Strength, Split Tensile Strength and Shear Strength compared with Reference Mixes of 0.5% GI-FRC and 1.0% GI-FRC.
