AbstractThis research covers the use of cellular lightweight concrete waste as recycled coarse aggregates to produce lightweight concrete. Various volume fractions of coarse aggregate (35%, 50%, and 75%) were used. The specimens were tested for compressive strength and density at age of 28-days. The compressive strengths for the resulting lightweight concrete with a density of (2131, 1826 and 1630) kg/m3 were (24, 22.6 and 11.5) MPa, respectively. In addition, silica fume was utilized as a constant replacement ratio 6% of cement weight for mixes lightweight aggregate to enhance the compressive strength of such concrete.
