Influence of steel and bamboo fibres on mechanical properties of high strength concrete

This paper evaluated the influence of steel and bamboo fibres on high strength concrete. samples of concrete cubes,beams and cylinders cast with varying proportions of steel and bamboo fibres were subjected to compression,flexural and splitting tensile strength tests respectively. a total of sixty three cubes of 100mm x 100mm x 100mm,fourteen beams of 100mm x 100mm x 500mm,and cylinders of diameter 100 mm and length of 150 mm were tested. the results revealed that concrete containing 1.0% bamboo fibre produced the greatest effect on flexural strength (81% increase in strength),and also on splitting tensile strength (101% increase). however,it was discovered that bamboo fibre has little or no impact on the compressive strength of high strength concrete. steel fibre-reinforced concrete generally produced an appreciable increase in compressive,flexural and splitting tensile strengths than the bamboo fibre-reinforced concrete.
