CHEM AER II is a liquid air entraining agent for concrete, ready for use. It complies with EN 934-2 Table 5.

USE

CHEM AER II added to the concrete reduces the weight while increasing the volume of concrete by entraining large numbers of correctly sized voids into it.

ADVANTAGES

• It decreases water permeability.
• It reduces the cracking probability during the setting.
• It increases the workability, while reducing the necessary water amount.
• It reduces the risk of segregation in transit.
• It improves water tightness of the concrete mass.

INSTRUCTIONS

CHEM AER II is added to the mixing water prior to its addition to the aggregates.

Dosage: From 0.01 to 1% on cement weight (from 10 gr to 1000 gr per 100 kg of cement). The dosage depends on the aggregates grading, the grade and proportion of sand, the W/C ratio, the cement fineness and quantity per m³, the temperature etc. In order to determine the exact dosage, on-site tests are recommended.

USEFUL DATA

Packaging: IBCs of 1000 kg, drums of 200 kg.

Shelf life: At least 6 months in the original sealed drums at a cool spot. If frozen, it can be defrosted at low temperature (30°C) under continuous stirring and used without problem.

CHEM AER II is compatible with the range of admixtures offered by our company.
