Impact Strength of Bio-Fibrous Concrete
Concrete is one of the most widely used materials in the world. Concrete is utilized in the construction of buildings, bridges and roads owing to their advantageous properties. However, occurrence of cracks in concrete poses a great hazard to the durability of concrete that could result in decrease of the service life of the structures. Researches have come up with numerous solutions to overcome this problem which include using bacteria to self-heal concrete and using Fibre-Reinforced Concrete (FRC). In this study, bacteria of genus bacillus which is bacillus subtilis was used to examine the effects of bacteria in concrete. Kenaf fibre which is a type of natural fibre was added into the concrete mix at 1%, 2% and 3% quantity to evaluate the strength of concrete. Concrete mix of water-cement ratio 0.45, 0.50, 0.60 were designed and casted in cylindrical shaped moulds. The testing of the concrete samples was carried out at 56th day with the aid of the impact testing machine to analyze the impact resistance of the samples. Results obtained from this investigation show that the concrete samples with the lowest water-cement ratio have the highest impact strength while samples with the highest water-cement ratio have the weakest impact strength. The presence of kenaf fibre in the concrete helped the concrete to gather more strength to achieved their ultimate rack resistance.
