Hydrocon ST
Cement hydration controlling admixture
Hydrocon ST is a liquid admixture formulated from selected polymers specially designed to retard the setting time by controlling the hydration process of Portland cement and other cementitious materials for long time.
This effect can be used to keep concrete workable for long time starting from 3 hours till three days.
- Reduce concrete waste in case of changing concrete casting schedule.
- Excellent retardation for long time up to 3 days.
- Excellent slump retention for very long concrete deliveries.
- Saving transit mixers drums in case of accident.
- Reduce the needed amount of water to clean transit mixer.
- Chloride free.
- For wet type shotcrete.
- For long distance concrete delivery.
- High performance concrete.
- Concrete washwater stabilization.
- To avoid setting of concrete in transit mixers in case of accident.
Hydrocon ST is available in 25 litre pails, 210 litre drums and 1000 litre bulks supply.
Hydrocon ST has a shelf life of 12 months from date of manufacture if stored at temperatures between 2°C and 50°C.
The guidance dosage of Hydrocon ST is 0.1 - 3.0 litre/100 kg of cementitious materials in the mix, including GGBFS, PFA or microsilica.
Representative trials should be conducted to determine the optimum dosage of Hydrocon ST to meet the performance requirements by using the materials and conditions in actual use.
Hydrocon ST complies with ASTM C494, Type B.
