CarbonCure’s Impact on Concrete Mixture Type CEM II/A-L 42.5 (14% Limestone ) Cement and 30% GGBS – Strength Improvement
This paper reviews strength gains in Type CEM II/A-L 42.5 (14% limestone) cement and 30% GGBS concrete mixtures both with and without the use of CarbonCure technology. The CarbonCure ready-mix technology produced concrete with a binder system comprising 70% CEM II/A-L 42.5 cement containing 14% limestone and 30% ground granulated blast-furnace slag (GGBS). The mix was produced with CO2 which was added like an admixture. The added CO2 enhanced the 28-day compressive strength by 7% over a reference mix.
