MAE research team has successfully 3D-printed a material that resembles concrete by combining fly ash, steel slag - a by-product of the steel-making process - and some chemicals, the identity of which is a trade secret. The project has been in the making for two years, said lead researcher Assoc Prof Tan Ming Jen.
The wide usage of such a material, if made from incinerator fly ash in future, could channel waste away from Singapore's only landfill in Pulau Semakau, potentially prolonging its lifespan, which is currently expected to end by 2035. Associate Professor Tan also said that the material could help cut the construction industry's carbon footprint as well.
