Flexural toughness and evaluation method of steel fiber reinforced self-compacting lightweight aggregate concrete
Highlights The flexural toughness and evaluation method of SFSLC were studied. The applicability of ASTM C1609 and JG/T 427-2015 methods was studied. A new flexural toughness evaluation method for SFSLC was proposed.
Abstract The main purpose of this study was to investigate the effect of steel fiber on the flexural toughness of steel fiber reinforced self-compacting lightweight aggregate concrete (SFSLC). The applicability of the flexural toughness evaluation method specified in ASTM C1609 and JG/T 472-2015 for SFSLC was investigated. Test results showed that the evaluation methods in ASTM C1609 and JG/T 472-2015 were not suitable for evaluating the flexural toughness of SFSLC due to its higher deflection than fiber reinforced normal concrete. A new flexural toughness evaluation method including four indexes was proposed and test results showed that this new method could effectively reflect the flexural performance of SFSLC.
