Abstract

Lightweight concrete production using melamine formaldehyde (MF) waste as fine aggregate by partially replacing
river sand was investigated. Two forms of MF waste, granules and waste powder, were employed to produce the concrete of
1,000 and 1,300 kg/m
³
. The replacements were 0%, 15%, 25% and 35% by weight with constant water-to-cement and cement-tofine aggregate ratios of 0.5 and 1.0, respectively. The concrete containing 25% waste powder was found to achieve the highest
compressive strength and comply with the ASTM standard for non-load-bearing lightweight concrete. The results revealed the
potential of MF waste recycling as fine aggregate in lightweight concrete.
