ANFIS MODEL FOR THE PREDICTION OF COMPRESSIVE STRENGTH OF CONCRETE FOR FRESH CONCRETE PROPERTIES

35765

The hardening process of concrete is irreversible, and properties of fresh concrete directly affect the hardening process and afterwards its hardened properties. Compressive strength is one of the most important mechanical properties of hardened concrete because it is related to other properties or performance of concrete such as bending, tensile, elasticity and durability. In this study, the ANFIS models were developed to estimate the concrete compressive strength from partial-volume ratio of concrete components and flow properties.While lowest coefficient of determination is obtained (R^2= 0.369) from modeling using of only flow properties as input parameters, modeling using of only partial-volume ratio of concrete components as input parameters is higher (R^2= 0.673) than modeling of flow properties. However, the best results (R^2= 0.961) is obtained from modeling using both variables as input parameters. As a result suggest that ANFIS can be used as an alternative approach to estimate compressive strength when it is used together partial-volume ratio of concrete components with flow properties as input parameters.
