Overview
EN 12390-10:2018 - Testing hardened concrete. Part 10 specifies a laboratory and field procedure to determine the carbonation resistance of concrete at atmospheric CO2 levels. The standard defines how to measure the carbonation rate (expressed in mm/√a) using either a standardized climate controlled chamber (reference method) or a natural exposure site protected from direct rainfall. It is intended for initial testing and research, not for factory production control.
Key topics and requirements
- Objective: Determine carbonation depth and calculate the carbonation rate of freshly cast concrete.
- Specimens: Pairs of prismatic beams (reference) or cubes cast from a single batch; curing and handling per EN 12390-1 / EN 12390-2.
- Reference chamber conditions: CO2 ≈ 0.040% by volume (400 ppm), temperature 20 ± 2 °C, relative humidity 65 ± 2% (see Annex A for chamber guidance).
- Natural exposure option: Specimens placed on a sheltered site with monitoring of CO2, temperature and RH (see Annex B).
- Measurement: Use phenolphthalein (1 g in 70 ml ethanol + 30 ml water) or an alternative pH indicator to reveal carbonation depth. Measure at multiple points per face (precision 0.5 mm) and compute mean depth.
- Instrumentation precision: CO2 recording ±0.001% by volume; RH ±1.0%; temperature ±0.5 °C.
- Test ages: The procedure requires repeated measurements at defined exposure ages (commonly multiple ages over months) to determine the rate in mm/√a.
- Safety note: Phenolphthalein is on the REACH candidate list; handle with care in a fume hood and use PPE.
Applications
- Assess the effect of cement type, admixtures, mix proportions (w/c ratio) and fines content on carbonation resistance.
- Provide input data for durability and corrosion-initiation models of reinforced or prestressed concrete.
- Support material qualification, comparative studies, research, and development of concrete mixes aimed at improving long-term durability.
- Serve as a reference method when establishing equivalent durability procedures or classifying concretes by carbonation performance.
Who uses this standard
- Concrete technologists, durability engineers and research laboratories
- Material suppliers and cement/admixture manufacturers
- Structural designers and asset owners assessing service life and reinforcement corrosion risk
- Standards bodies and testing laboratories validating new mixes (not for routine factory QC)

4 Principle Pairs of beams of concrete (or two cubes per test age) from the same batch of concrete are stored in a climate controlled chamber as specified in 5.4 or on a natural exposure site as specified in 5.5. After defined periods of exposure, an approximately 50 mm thick slice of the beam is broken off at each test age and tested for its carbonation depth. If cubes are being used, they are broken in half and one half of each cube is used to measure the carbonation depth, the other half being discarded.
The carbonation depth is measured at three locations on each face of each beam/cube giving a potential total of 12 measurements per specimen and potentially 24 measurements for the two specimens. The mean carbonation depth of all measurements is calculated. The remains of the beams are returned to the climate controlled chamber for testing at other pre-defined ages. Using at least three sets of measurements taken at 3 months, 6 months and 1 determined. SIST EN 12390-10:2019
If this is not possible, local meteorological data can be used. 5.6 Apparatus for recording the relative humidity, which ensures a precision of the measurement of ± 1,0 %, and the temperature with a precision of ± 0,5 °C. 5.7 Apparatus for recording CO2 concentration with a precision of ± 0,001 % by volume. If a climate controlled chamber is being used, it shall be fitted with an audible/visual/electronic alarm to signify breaching of limits. 5.8 Fan to provide a homogeneous CO2 concentration in the air. Type, dimensions and power of the fan has to be adapted to the dimension of the chamber. 6 Production of specimens 6.1 General Representative samples of the constituents, e.g. cement, aggregates, shall be used for making the test specimens. Either a sample of concrete is taken from the concrete production plant or the concrete mixes shall be produced using the laboratory’s standard procedures. The specimens for one test, which include specimens for the carbonation test and compressive strength tests, shall be cast from a single batch of concrete. For laboratory production, a minimum batch volume of 50 l is recommended. SIST EN 12390-10:2019
This is either by horizontal storage or vertical storage, but ensuring a 50 mm gap between adjacent specimens. The temperature shall be measured at least once per day at a constant time. The relative humidity and carbon dioxide concentration shall be measured and recorded at least once every two hours. The average carbon dioxide concentration in the climate controlled chamber over the duration of the test shall be (0,040 ± 0,001) % with no variation outside (0,040 ± 0,005) %. 6.3 Procedure when using a natural exposure site For each concrete mix, cast at least two beams or at least six cubes for carbonation testing and at least 2 or if the strength development is not known, at least 5 compressive strength specimens from a single batch of concrete. The test specimens shall be cast horizontally in accordance with EN 12390-2. After finishing the test specimens, cover the exposed surface with polythene or similar impermeable sheeting to prevent drying.
After (24 ± 2) h, the moulds shall be stripped and the carbonation test specimens transferred without delay into close-fitting, sealed polythene bags or similar storage material and stored at (20 ± 2) °C until they have reached 50 % of the reference strength. If the temperature range is from 15 °C to 25 °C, 50 % of the reference strength may be assumed to have been achieved after 2 days for rapid, 4 days for medium and 7 days for slow concrete strength development.
If the strength development is not known at least three cubes or cylinders shall be tested at different ages to ascertain when 50 % of the reference strength has been
