Abstract

It this study, the application of artificial neural networks (ANN) for estimating the characteristic strength of sustainable concrete that contains various amounts of fly ash, silica fume, slag and steel fiber have been investigated. Using ANN model, it is possible to establish a linear and nonlinear correlation between known input data like concrete ingredients and a certain output like characteristic strength, because ANN is an excellent tool to determine concrete properties. For the training of ANN models, an experimental data base (1410 concrete mixtures from earlier published papers) has been utilized. Then experimental tests were performed on some mixes of concrete to validate the model. The ANN model parameter statistics R2 is 0.888, 0.93, 0.9 for training, validation and test steps and indicate that ANN model makes effective prediction for characteristic strength of sustainable concrete. The application of ANN in predicting characteristic strength is considered to the quality assurance of manufacturing of concrete.
