Abstract: In this research, a three parameter Weibull probability distribution was used to model the reliability of the flexural strength of inexpensive porous sintered clay. The as-received clay and the porous sintered clay were characterized by XRF, XRD, BET and FESEM. The clay powders mixed with 10wt% cassava starch were compacted and sintered at a temperature of 1300°C. The flexural strength of the sintered samples (33 samples) was determined by three point bending test. The flexural strength data was analyzed using three-parameter Weibull with Minitab 15 software. Maximum likelihood (ML) and least square (LS) estimates were employed in determining the Weibull parameters. The Weibull modulus value of LS (3.28) was found to be higher than ML (2.21). the Weibull modulus obtained is found to be higher compared to other engineering materials while the threshold strength (11.18-12.97MPa) was lower than other engineering materials. The flexural strength analysis of porous sintered clay shows higher reliability and a three parameter Weibull gives detail reliability of the flexural strength of the porous sintered clay
