Concrete Accelerating AS-1
Description: AS-1 is a high range water-reducing additive based on modified melamine sulphonate.
AS-1 is used as an accelerating agent that its first day compressive strength will be over 100 kg/cm^2.
AS-1 is a chloride free admixture and complies with ASTMC-494TypeE.

Uses: - Prefabricated concrete members
- Concreting on slop surfaces
- Quick repair works
- Concreting in low temperature

Advantages: - Increasing slump up to 300% in constant W/C
- Shortening mould time
- High initial and ultimate strength
- Reducing the risk of stress cracks
- Compatible with all types of Portland cement.

Dosage: The normal dosage is 0.5 to 1% of cement weight.
Application: Reduce at least 12% of the mixing water, then add AS-1 to it and mix it for 3 minutes.
For long distance transport it is better to add AS-1 at site and mix it further 2 minutes for each cubic meter of concrete
