<![CDATA[Flexural strength is one of the mechanical properties of concrete that should be tested, especially for concrete that serves as a beam and is subjected to flexural loads. However, the assessment of flexural strength in concrete frequently relies solely on a mathematical approach that several previous researchers have found. Concrete structures continue to evolve, particularly in the use of more diverse and sustainable constituent materials. Meanwhile, the generated equations use conventional concrete without adding cementitious or replacement components. Therefore, it is necessary to investigate whether these equations can accurately predict the flexural strength of concrete with diverse constituent materials. This investigation was undertaken by reviewing 72 data sets derived from the experiment by previous researchers. Each set of test data will be compared to various formulas and will also be compared to the analysis performed using Response-2000. The results show that the correlation between Response-2000 and the experiment was 0.8207 with the linear regression equation y = 1.1326x + 1.0016. The flexural strength analysis using various approach formulas resulted in an average correlation R² of 0.8246, or 82.46% correlated to the results of the flexural strength of laboratory tests.]]>
