Hydrocon
R3

CEMENT HYDRATION CONTROLLING ADMIXTURE
 
Advantages:
  • Reduces concrete waste in case of changing concrete casting schedule
  • Excellent retardation for a long time up to 3 days
  • Excellent slump retention for very long concrete deliveries
  • Saves transit mixer drums in case of accidents
  • Reduces the needed amount of water to clean the transit mixer
  • Chloride-free
Description:

Hydrocon R3 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 a long time. 

This effect can be used to keep concrete mixes workable for a long time starting from 3 hours till three days.

Usage

  • For wet type shotcrete
  • For long-distance concrete delivery
  • High-performance concrete
  • Concrete wash water stabilization
  • To avoid setting of concrete in transit mixers in case of an accident

Materials Supplied

Hydrocon R3 is available in 5 gal (19 litre) containers as well as 275 gal (1,041 litre) and 330 gal (1,249 litre) IBC totes. Bulk supply in tanker trucks is also available upon request. 

Shelf Life

Hydrocon R3 has a shelf life of 12 months from date of manufacture if stored properly in its original unopened packing at temperatures between 35°F and 122°F (2°C and 50°C).

Application Instructions

Hydrocon R3 should be added to the concrete with the mixing water to achieve optimum performance. Also it can be added directly to the drum of concrete mixers when unplanned changes in concrete casting schedule.

DOSAGE

The recommended dosage of Hydrocon R3 is between 2.5 to 123 fl oz/100 lb (163 to 7,995 ml/100 kg) of cementitious materials in the mix, including GGBFS, PFA or micro-silica. Actual dosage depends on the desired retardation.

Representative trials should first be conducted to determine the optimum dosage of Hydrocon R3 to meet the performance requirements by using the materials and conditions in actual use.

For traditional compliance with ASTM C494, the recommended dosage is between 2.5 to 10 fl oz/100 lb (163-650 ml/ 100 kg) of cementitious materials in the mix.

EFFECTS OF OVER DOSAGE

Overdosage of Hydrocon R3 will cause the following:

  • - Significant increase in retardation.
  • - Increase in workability.
HEALTH AND SAFETY

Hydrocon R3 is not classified as a hazardous material. Hydrocon R3 should not come into contact with skin and eyes.

In case of contact with eyes, immediately flush with plenty of water and seek medical attention.
