Accelerated carbonation test data for concretes with varying slag content.

Area of Science:

• Materials Science
• Civil Engineering
• Environmental Science

Background:

• Concrete durability is crucial for infrastructure longevity.
• Carbonation is a primary degradation mechanism affecting concrete service life.
• Understanding factors influencing carbonation is essential for sustainable construction.

Purpose of the Study:

• To present a detailed dataset of accelerated carbonation test results for diverse concrete mixes.
• To provide raw and processed data for material properties, exposure conditions, and carbonation depths.
• To facilitate research in concrete mix design, service-life modeling, and carbonation performance comparison.

Main Methods:

• Prepared 48 concrete mixes with varying cement types and ground granulated blast-furnace slag (GGBS) content (0-72%).
• Tested air-entrained and non-air-entrained concrete versions.
• Conducted accelerated carbonation tests at ~3% CO₂ concentration and measured carbonation depth up to 84 days.

Main Results:

• Collected extensive data on fresh and hardened concrete properties.
• Recorded carbonation depth measurements and derived carbonation rates for all mixes.
• The dataset includes material properties, exposure conditions, and carbonation measurements.

Conclusions:

• The dataset offers valuable resources for concrete research and development.
• Enables benchmarking of concrete mix designs and validation of service-life prediction models.
• Facilitates comparison between accelerated and natural carbonation phenomena.
