Measurement and prediction of the strength of rubberized concrete

摘要: Abstract Illegally discarded piles of automobile tires are sources potential hazards. Current disposal methods wasteful and costly as they require either consumption landfill space or continuous maintenance. A solution to the problem scrap-tire is use tire chips crumb rubber mineral aggregate substitutes in Portland cement concrete mixes. In this study, some engineering properties rubberized were examined a neural network was developed predict its compressive tensile strengths. Rubberized found possess good esthetics, acceptable workability, smaller unit weight than normal concrete. However, did not perform well under repeated freeze-thaw cycles. It exhibited lower strength that Unlike concrete, had ability absorb large amount plastic energy loads. demonstrate typical brittle failure, but rather ductile, failure mode. Test results analyzed so model can be Two models reduction result replacing with aggregate. maximum difference 9·2% between test prediction detected during testing networks.
