Synthesis and properties of a novel structural binder utilizing the chemistry of iron carbonation
S Das, B Souliman, D Stone… - ACS applied materials & …, 2014 - ACS Publications
This paper explores, for the first time, the possibility of carbonating waste metallic iron
powder to develop sustainable binder systems for concrete. The fundamental premise of this
work is that metallic iron will react with aqueous CO2 under controlled conditions to form
complex iron carbonates which have binding capabilities. Chosen additives containing silica
and alumina are added to facilitate iron dissolution and to obtain beneficial rheological and
later-age properties. Water is generally only a medium for mass transfer in these systems …
