Application Instructions

DOSAGE

Sprayed trials should be conducted to determine the optimum dosage of Proset AF to meet the performance requirements by using the materials and conditions in actual use.

Dosage of Proset AF will vary depending on the performance requirements of the sprayed concrete, cement type, age and content, temperature of the sprayed concrete, substrate and air, the water to binder ratio as well as the other admixtures and materials in the concrete mix.

Typical dosage is between 5.0 - 7.0 litre/100 kg of cementitious and cement replacement material, including PFA, GGBFS or microsilica, which can be used as a starting point for the trials.

EFFECTS OF OVER DOSAGE

Overdosing of Proset AF will decrease the ultimate concrete strength.

APPLICATION

In the case of wet-mix and dry-mix sprayed concrete, Proset AF should not be added to the cement mixer or concrete mix, but through a liquid dispensing system that connects to the main hose right at the nozzle.

In both sprayed concrete methods, the minimum cement weight per cubic meter of the concrete mix should be no less than 350 kg/m3.

HEALTH AND SAFETY

Proset AF is not classified as hazardous material. Proset AF should not come into contact with skin and eyes. Goggles and gloves should be used.

In case of contact with eyes wash immediately with plenty of water and seek medical advice promptly.
