| Abstract [eng] |
Today, municipal solid waste incineration (MSWI) is considered the most sustainable and advanced technology worldwide for municipal waste utilization, with the lowest environmental impact. Bottom ash (BA) and fly ash (FA) are the secondary raw materials generated in MSWI processes. The research focused on the effective utilisation of bottom ash (FA) from municipal waste incineration plants. Mechanical and durability properties of mortars, in which up to 40% of cement was replaced with BA at 5% increments, were tested in detail. BA structures were analysed using X-ray diffraction and SEM methods. Test results showed that the replacement of fine aggregate with BA increased water absorption of mortars and decreased compressive strength and frost resistance. The research leads to the conclusion that cement-based structures can be modified with MSWI bottom ash at the rate of 10–15%. |
