Mechanical and thermal insulating properties of the lightweight MSWI concrete blocks
Martin KEPPERT, Kirill Polozhiy
University Centre for Energy Efficient Buildings of Czech Technical University in Prague

2. Objectives
utilization of Municipal Solid Waste Incineration bottom ash (BA) for production of light-weight concrete
MSW incineration – ca. 50 % of MSW in Europe is incinerated
bottom ash – wide range of particles size, separation of Fe, Al, glass – the rest can be used as aggregates
sieve size (mm)

3. Methods preparation of „no-fines“ concrete with various combinations
of BA and natural aggregates
0-1 mm
2-4 mm
4-8 mm
8-16 mm
