The mortar samples prepared in 5 different concentrations with a total of 2.5%, 5%, 10%, 20% and 30% PET aggregate substitution were heated up to 100, 150, 200, 250, 300 and 400 degrees C. After waiting for 1, 2 and 3 h at these temperatures, flexural and compressive strength tests were performed. It was observed that flexural strength and compressive strength values decreased with increasing temperature and PET aggregate amounts in all mixtures. An artificial neural network was designed to estimate flexural and compressive strength values using experimental data. It has been observed that the developed artificial neural network can predict flexural and compressive strengths with an average error of - 0.51%.eninfo:eu-repo/semantics/closedAccessWaste PET aggregateFlexural strengthCompressive strengthElevated temperatureArtificial neural networkArticle4654867488110.1007/s13369-020-05280-12-s2.0-85099253892Q1WOS:000605157700030Q2
