Proset AFR
Alkali free sprayed concrete accelerator, with minimum rebound characteristics
Proset AFR is a set accelerating, alkaline and chloride free admixture specially designed to achieve rapid setting with minimum rebound for applications of sprayed concrete, shotcrete and gunite processes.
- Rapid set allows thick sections to be built-up.
- Alkaline free.
- Minimum rebound.
- Single pass spraying for thick layers.
- Excellent for overhead applications.
- Can be used for ‘wet and dry’ processes.
Proset AFR is available in 275 kg plastic drums supply.
Proset AFR has a shelf life of 6 months from date of manufacture if stored in a dry area out of direct sunlight and exposure to frost in original unopened container at temperatures between 5°C and 35°C.
Material needs good mixing before usage, and for bulk storage, site agitation or recycling pumps is a must.
The optimum dosage for Proset AFR to meet specific requirements should be determined by trials using the materials and conditions that will be experienced in use.
This can best determine the optimum dosage to be used and will ensure most cost effective site application.
The typical dosage range for Proset AFR is 7.0 - 10.0 kg per 100 kg of cementitious and cement replacement material, including PFA, GGBFS or microsilica, which can be used as a starting point for the trials.
Proset AFR complies with ASTM C1141, Type I and II, Grade 9.
