Description
Summary:In the present work, incineration bottom ash (IBA) from municipal solid waste incinerators (MSWI) was considered as fine aggregate for the production of lightweight foamed concrete (LFC). The raw IBA collected was undergoes series of treatment process to decrease its chloride and aluminium content that possibly affect the concrete performances. Chemical compositions of IBA at different stages of treatment were determined. Four design mix compositions of LFC comprising 5%, 10%, 15% and 20% replacement of sand by pre-treated IBA (PIBA) and two control mixes consist of normal weight concrete (NWC) and LFC were formulated and cast in 100 mm cubes. The compressive strengths of LFC with 5% replacement was able to achieve the compressive strength of 35.0 MPa, while 10% replacement gives strength that similar to NWC concrete grade C25, with their dry density of 18% less than NWC.
