Japan: A team at the University of Tokyo has developed cement-free alternative concrete from ultra-fine sand and fly ash. NHK has reported that the process uses recyclable alcohols and has lower CO₂ emissions compared to concrete production using ordinary Portland cement. Research with industrial partners into possible construction sector applications is underway. Partnerships with Japanese ready-mixed concrete producers are reportedly also under discussion.

Further information is available from Yuzo Tobisaka, an independent Japanese consultant in the cement and ready-mixed concrete industry, at yuzo.tobisaka@gmail.com.
