Across the world, the acceptance criteria for concrete cast with non-potable water (SA) is stipulated for mean strength with reference to similar concrete cast with potable water (SP). The basis for strength design of concrete is characteristic strength. Effect of the former criteria on the characteristic strength of SA vis-à-vis SP – was examined using statistical simulations, for the first time in this study. It was concluded that using 3-sample set would improve the characteristic strength of SA compared to 2-sample set. Higher allowable ratio between mean of SA and SP, and lower deviation of individual sample from mean would improve characteristic strength of SA. The effect of the COV of the original population on the characteristic strength of SA varies: on one hand the higher COV reduces the characteristic strength of SP thereby increasing the probability of SA being higher than SP; on the other hand, the higher COV of SP meant wider spread of the samples and that could increase the COV of SA – thereby reducing the characteristic strength of SA. Probabilistic charts were developed for characteristic strength of SA vis-à-vis SP, for different combinations of the aforementioned variables, with guidance for practical application.
