Abstract

This study evaluates the splitting tensile strength of lightweight foamed concrete (LWFC) reinforced with steel fibres from waste tyres. The volume fractions of the steel fibres used were 0%, 0.2%, 0.4%, and 0.6% by total volume of concrete. Mix ratio of 1:2.25 (cement: sand) was used with 0.5 water/cement ratio. The splitting tensile strength decreases as the steel fibres increases from 0% to 0.4%. It became higher for 0.6% steel fibre content which had splitting tensile strength of 0.66 /���, 1.08 /��� and 1.46 /��� at 7, 14 and 28 days respectively. The results of the LWFC mixes showed a decrease in the splitting tensile strength for the specimens as the steel fibre content increased till it became adequate at which point the splitting tensile strength increased. These results are then checked with the Scanning Electron Micrographs (SEM) of the samples with different percentage of steel fibre content.
