CarbonCure FAQ for Engineers

A wide range of technical data which illustrates how CO₂ has a neutral impact on the properties and performance of concrete mixes.

CarbonCure Infosheet for Designers and Builders

Key facts owners, developers, architects, structural engineers and contractors need to know about building with CarbonCure concrete.

CarbonCure’s Impact on the GWP of Concrete

Concrete made with CarbonCure reduces the carbon impact (GWP) of concrete by 4-6% and may be used in addition to other carbon-reducing strategies.

CarbonCure Ready Mix Specification Language

Recommended specification language for incorporating concrete that has undergone in-situ carbon dioxide (CO₂) mineralization using CarbonCure's technology into ready mix concrete specifications and/or procurement policies.

Specification Considerations for Engineers

Structural engineers play a vital role in reducing embodied CO₂ by adopting concrete specification best practices, which are contained in this brochure.

CarbonCure Durability Assessment Report

This technical note reviews the conclusion that concrete treated with CO₂ had fresh state properties consistent with the desired performance. The required workability and air content was achieved. The surface resistivity, bulk resistivity and RCPT indicated that the two batches had comparable permeability. Corrosion measurements indicated corrosion had not started in either sample and pore solution pH was unaltered by the CO₂ treatment. Flexural strength increased 6%.

Types of Concrete 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.

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.
