Brittleness and crack formation are weaknesses of concrete related to its durability. The present research trend in concrete technology is towards increasing the strength and durability of concrete to meet the demands of the modern construction. Fibers are added to concrete primarily to control the propagation of cracks and limit the crack width. This paper deals with experimental investigations carried out on M25 grade of concrete reinforced with carbon fiber dosages of 0%, 0.75%, 1.00% and 1.25% by weight of concrete. The strength and durability characteristics are studied. The mechanical properties studied are compressive, split tensile and flexural strengths. The test specimens were also subjected to acid and sulphate attacks and tested for their durability. The results show that there is an increase in compressive, split tensile and flexural strengths of carbon fiber reinforced concrete. Inclusion of 1% carbon fibers showed the maximum enhancement in strength and it can be considered as optimum dosage. When compared to conventional concrete, the crack width also reduced in carbon fibre reinforced concrete. Key words: Carbon fibre reinforced concrete (CFRC), compressive strength, tensile strength, flexural strength, acid attack test, sulphate attack test.
