Precast Concrete Carbonation under Ambient Conditions

This project seeks to explore the practical viability of curing concrete via carbonation at ambient pressure conditions, thereby omitting the techniques current dependency on elevated pressures. A vacuum pre-setting step and regimented CO2 injections highlight the proposed technique. Experiments will initially be carried out at the laboratory scale at the university, and then scaled up to pilot trials to be conducted at the partners industrial site. Tests and analyses include compressive strength, absorption, porosity, surface resistivity, mineralogy, microscopy, and thermal analysis. Promising outcomes will help the industrial partner expand on its commercial implementation of carbonation curing, and promote further adoption by the concrete precast industry.
