EFFECT OF ADDITION OF CARBON FIBRES ON PROPERTIES OF HIGH PERFORM CONCRETE

In this paper, some preliminary results obtained in a laboratory investigation on the use of carbon fibres in HPC are reported. Concrete mixes made of 10 mm basalt aggregate having 28 day compressive strengths in the range of 50-100 MPa were tested. On fresh concrete, slump, compacting factor and Vebe tests were carr out to assess the workability of these mixes. Mechanical propert and stress-strain relationships in compression of carbon fibre reinforced concrete (CFRC) were obtained and compared with those plain concrete. Carbon fibres (monofilaments) of 6 mm in length used for all the mixes reported in this paper. For most mixes, percentages of carbon fibre were kept to a minimum of 0.1% to 0.5 weight of concrete (Vf = 0.13% to 0.67%) but some results obtaine for mixes with 1% and 2% (Vf = 1.3% and 2.6%) are also presented comparison. The improvement in compressive strength and modulus elasticity was moderate. A reasonable amount of increase in flex tensile strength and indirect tensile strength was recorded. The effect of addition of carbon fibres on the stress-strain behaviou compression was significant. (a)
