Gasification residues - a challenge to make durable & environmentally friendly concrete

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientific


New concepts for dealing with recycled materials and biofuels are being explored. Development work has been done for years to gasify this type of wastes. The produced gas is cleaned from the solid residues that are cement-sizes dusts. They exhibit pozzolanic reactivity which varies according to the source fuel. Unfortunately, the residues can also contain harmful compounds which limit their use. If applicable building materials are found in which the residues can be utilised it would mean a significant advantage for further introduction of gasification techniques in modern societies. The properties of six gasification residues were studied for their suitability in compacted concrete.
