Flexural-tensile properties of layered steel fiber reinforced rubber concrete

Abstract

Layered steel fiber reinforced rubber concrete (LSFRRC), a new type of pavement concrete based on the requirements of national standard were experimentally researched. The different properties of flexural-tensile strength from plain concrete (PC), rubber concrete (RC), layered steel fiber reinforced concrete (LSFRC) and LSFRRC were presented. Experimental results show that the tensile strength of LSFRRC is improved by 4.12% compared with PC, by 13.75% compared with RC. The load-deflection curve on flexural-tensile propertiesis put forward. The flexural-tensile toughness index I10 of LSFRRC is improved 10.32 times compared with PC.
