Abstract

In this research, the utilization of melamine formaldehyde waste (MFW) as a fine aggregate in lightweight concrete was investigated. The MFW was used for replacing river sand 25% by weight with constant water-to-cement and cement-to-fine aggregate ratio of 0.5 and 1.0, respectively. Mechanical property tests were conducted on compressive strength and water absorption. The analysis of mechanical properties of lightweight concrete containing MFW was done by using 2k factorial design. Three factors of interest are MFW ratio, density and foaming agent. The results revealed that MFW could be potentially used in lightweight concrete with determined percentages. We ensured that the compressive strength and water absorption results are within the Thai Industrial Standards.
