FAQ for Ready Mix Quality Control Personnel

The CarbonCure Technical Team has provided answers to frequently asked technical questions regarding how the installation and use of the CarbonCure Technology will affect your plant's operations and final product. 


CarbonCure's effect on durability of concrete

Carbon dioxide was investigated for use as a beneficial admixture to concrete as it was truck mixed. Comparisons of the fresh, hardened and durability properties were made between a reference concrete batch, a batch that contained a conventional accelerating admixture, and three batches subjected to a carbon dioxide addition. The following conclusion were made:

  • The optimum dose of carbon dioxide was found to reduce the time to initial set by 40% and increase the one and three day compressive strengths by 14% and 10% respectively.

  • Concrete durability test results indicated that the carbon dioxide process did not compromise the expected durability performance of the treated concrete.

  • Carbon dioxide is a viable admixture to improve concrete performance.


Ready Mix Technology Case Study

This case study examines data provided by a CarbonCure producer partner who installed the CarbonCure Technology and used the system to produce concrete with an optimized dosage of CO2.

  • 45 000 yd3 of concrete were produced over an 8 month period using a 5% binder reduction in conjunction with an optimized dose of CO2.

  • The estimated cement savings exceeded 450 tonnes and more than 400 tonnes of CO2 emissions were avoided.

  • The use of the technology did not impact the producer’s cycle time; all operations continued as normal throughout this assessment.


On carbon dioxide utilization as a means to improve the sustainability of ready mix concrete

This paper shows how the injected carbon dioxide 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 carbon dioxide 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%.


Technical Notes

Differences between CarbonCure carbonation & weathering carbonation 

Concrete can be subjected to two distinct types of carbonation, weathering carbonation and early age carbonation. The CarbonCure Technology uses early age carbonation to sequester CO2 into concrete. The document explores both types of carbonation in more detail.

Impact of CO2 utilization on concrete pore solution pH

This document explains how the early age carbonation that takes place during the application of the CarbonCure Technology does not hinder the long-term development of the concrete microstructure as the concrete matures - including the pH of the pore solution.  


CarbonCure's effect on fresh concrete properties

This document outlines the beneficial reaction between carbon dioxide and freshly hydrating cement. A detailed explanation on the chemical process that takes place as CO2 is injected into fresh concrete is provided.

Overview of CarbonCure's ready mix technology system & plant integration

This document explains how the CarbonCure Technology can be easily integrated into any ready-mixed concrete facility with minimal disruption to regular production. The five main components of the CarbonCure Technology and with plant integration requirements are outlined.

Impact of CO2 utilization in fresh concrete on corrosion of steel reinforcement

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.

Concrete Blocks Manufactured Using Sequestered Carbon Dioxide

A retrofit system to inject gaseous carbon dioxide was attached to a conventional concrete mixer to produce blocks using a conventional medium weight block mix design and curing. The carbon dioxide was injected into the concrete during the mixing cycle. The carbonated blocks were found to display improved performance relative to the control blocks at 7, 28 and 56 days. The carbon dioxide was sequestered in the product as nano-scale carbonate reaction products. The treatment served to improve the environmental footprint of the treated blocks.
