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.

CarbonCure’s Impact on Type I/II Cement – Strength Improvement

This paper reviews the impact of CarbonCure ready-mix technology produced concrete with a binder system comprising 100% Type I/II cement. The mix was produced with CO2 which was added like an admixture. The added CO2 enhanced the 28-day compressive strength by 10% over a reference mix.

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

This paper reviews strength gains in Type I/II cement and Class C fly ash concrete mixtures both with and without the use of CarbonCure technology. The CarbonCure ready-mix technology produced concrete with a binder system comprising 75% Type I/II cement and 25% Class C 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.

CarbonCure’s Impact on Type I/II Low Alkali Cement & Metakaolin Concrete Mixtures

This white paper reviews CarbonCure's impact on a Type I/II low alkali cement and metakaolin concrete mixture. The CarbonCure ready-mix technology produced concrete with a binder system comprising 89% Type I/II low alkali cement and 11% Metakaolin. 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.

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

This paper compares strengths in Type I/II cement and Class C fly ash concrete mixtures both with and without the use of CarbonCure technology. The CarbonCure ready-mix technology produced concrete with a binder system comprising 75% Type I/II cement and 25% Class C 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.

CarbonCure’s Impact on Type I/II Cement Concrete Mixtures

This paper reviews CarbonCure's impact on Type I/II cement concrete mixtures. The CarbonCure ready-mix technology produced concrete with a binder system comprising 100% Type I/II cement. 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.

CarbonCure Ready Mix Technology Trial Results

Industrial pilot testing results of the carbonated ready mix concrete are presented in this technical note. The process created nanocrystalline carbonate reaction products that positively effected the early hydration and the compressive strength. The carbonated concrete was as much as 20% stronger than the control concrete without any compromise in pore solution pH or risk for chloride penetrability.

Calculating Sustainability Impacts of CarbonCure Ready Mix

This paper shows how the injected CO₂ improved the concrete’s compressive strength with minimal impact on fresh air content or workability. It includes three-way comparisons between a reference batch, reduced binder batch and reduced binder batch with CO₂ addition, confirmed that the CO₂ could allow for a 5-8% reduction in binder loading without compromising strength. A model case shows that integrating a CO₂ utilization step into conventional concrete production can, net of process emissions, reduce the carbon footprint of the concrete by 4.6%.

Impact of CO₂ Utilization in Fresh Concrete on Corrosion

This document explains the difference between early carbonation and atmospheric carbonation, and how early carbonation has a benign impact on steel corrosion. A detailed description of why early carbonation does not increase the risk of steel corrosion is included.
