In this study, structural lightweight concrete derived from coarse lightweight crushed brick and fine lightweight crushed brick (CLWA and FLWA) were investigated. Compressive strength and density of the concrete were determined to establish the appropriate design mix of lightweight concrete. The suitable designs of concrete mixture were selected to determine their using different percentages of palm fiber; 0, 0.2, 0.4, 0.6, 0.8, and 1.0% based on volumetric fractions. The results show that the voids between fine aggregate particles (sand + FLWA) had significant effect on the compressive strength of the crushed brick concrete. By using 0.6% of palm fiber, the compressive strength and flexural strength of the concrete mix increased by about 11.2% and 16.6%, respectively.
