Abstract
In this study, an attempt was made to investigate the effect of fire on impact resistance of tyre-rubber concrete (TRC), subjected to drop weight test in
accordance with the procedure suggested by ACI committee 544. For this, three samples were prepared from each series of mix containing tyre\ fibres of 10 mm width and length in various proportions viz., 0%, 2.5%, 5.0% and 7.5%, with a
water cement ratio of 0.55. The results obtained were statistically investigated using Weibull Distribution. The Weibull parameters were determined by three estimation approaches; EPM (Energy Pattern Method), Probability Density
Function (PDF) and Method of Moment (MOM). Analysis suggested that the three methods are more effective in estimating the weibull parameters.
Though there are less differences. Therefore, designers can choose impact strength design value based on the required reliability.
