Abstract
The statistical models illustrated the constitutive relationship between the fibre volume fraction and governing characteristics of concrete. Regression coefficient of determination obtained for the best fit in polynomial, Fourier, interpolant and basis spline functions. The relationship among compressive, flexural and pull-off strengths signifies through curve fitting with nearest neighbor interpolant. Estimated optimum value found for fibre concrete through executed result, provides an advance understanding of fibre concrete and further development in experimental performance of cementitious materials. This paper devotes the statistical capability of durable recycled material to resist the physical process and degradation processes during its service life with the minimal maintenance is equally important as the capacity. The mechanical characteristics and recycled brittle behaviour of the material remains a larger handicap flexible behaviour is essentially required. Reinforcement with randomly distributed short fibres presents an effective approach to the stabilisation of the crack and improving the ductility and tensile strength of concrete. Polypropylene fibre reinforcement is considered to be an effective method for improving the shrinkage cracking characteristics, toughness, and impact resistance of concrete materials. The statistical concert in fibre reinforced concrete by comparing various properties such as compressive strength, tensile strength, workability properties with various content of fibre.
