A green ultra-lightweight chemically foamed concrete for building exterior: A feasibility study
TLDR
In this paper, a green foamed concrete based on river sediment-metakaolin blends was proposed. But the results showed that the results were not as good as the results obtained for the traditional Portland concrete with a similar density.About:
