CarbonCure’s Impact on Concrete Mixture Type GU Cement – Mix Optimization

This paper reviews CarbonCure's Impact on Concrete Mixture - Type GU Cement. The CarbonCure ready-mix technology produced concrete with a binder system comprising 100% Type GU cement. The mix was produced with CO2 which was added like an admixture. The added CO2 enhanced the 28-day compressive strength by 22% over a reference mix.

CarbonCure’s Impact on Concrete Mixture Type IL Cement and Class F Fly Ash – Mix Optimization

This paper reviews CarbonCure's Impact on Concrete Mixture Type IL Cement and Class F Fly Ash. The CarbonCure ready-mix technology produced concrete with a binder system comprising 80% Type IL cement and 20% Class F fly ash. The mix was produced with CO2 which was added like an admixture. The added CO2 enabled the use of less cement content without compromising the strength properties of the mix while achieving an increase in compressive strength of 8% over a reference mix.

CarbonCure’s Impact on Concrete Mixtures Using Type IP Cement – Strength Improvement

This paper reviews strength gains in Type IP cement concrete mixtures both with and without the use of CarbonCure technology. The CarbonCure ready-mix technology produced concrete with a binder system comprising 100% Type IP cement. The mix was produced with CO2 which was added like an admixture. The added CO2 enhanced the 28-day compressive strength by 5% over a reference mix.

CarbonCure’s Impact on Concrete Mixtures Using Type II Cement – Strength Improvement

This paper reviews strength gains in Type II cement concrete mixtures both with and without the use of CarbonCure technology. The CarbonCure ready-mix technology produced concrete with a binder system comprising 100% Type II cement. The mix was produced with CO2 which was added like an admixture. The added CO2 enhanced the 28-day compressive strength by 12% over a reference mix.

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.

CarbonCure’s Impact on Concrete Mixture: Type CEM II/A-L 42.5 (14% Limestone) Cement – Strength Improvement

The CarbonCure ready-mix technology produced concrete with a binder system comprising 100% CEM II/A-L 42.5 cement containing 14% limestone. 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.

CarbonCure’s Impact on Type I/II Cement and Class C Fly Ash Concrete Mixtures – Strength Improvement

This paper reviews strength gains in Type I/II cement and Class C fly ash concrete mixtures. 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.
