Graph 5.4: Split Tensile Strength of Concrete Vs % of Bamboo Fibres

6. CONCLUSIONS

Based on the experimental investigation carried out, the following conclusions are made: 1.Maximum compressive strength of SFRC is 50.25Mpa achieved at 2% adding of concrete by steel fibres (M40grade). When compared to normal concrete it increases to15% 2.Maximum compressive strength of BFRC is 46.28Mpa achieved at 0.20% adding of concrete by polypropylene fibres (M40grade). When compared to normal concrete it increasesto 1.5% 3.Maximum split tensile strength of SFRC is 4.95Mpa achieved at 2% adding of concrete by steel fibres (M40 grade). When compared to normal concrete it increasesto 13% 4.Maximum split tensile strength of BFRC is 4.45Mpa achieved at 0.20% adding of concrete by Bamboo fibres (M40 grade). When compared to normal concrete it increases to 11%. 5.When compared to normal concrete mono fibres give maximum resultant.
