Yi Du was an invited speaker at the first RILEM European RYC-P2P-Webinar

Yi Du was one of the two invited speakers at the first European RILEM P2P webinar. Yi Du presented “A new low-carbon clay concrete with improved water resistance” developed during his PhD research. He discussed the combined use of Tannin and iron compound in poured earth: the former is used as a dispersant to liquefy clay materials, and the latter acts as an anti-tannin agent to slowly remove the dispersing effect and re-coagulate clay.
Improving the performance of poured earth is a key element to lead to a larger use of this material, in substitution of less sustainable and more conventional building solutions.
