AC – SET ACCELERATOR
DESCRIPTION CHARACTERISTICS / ADVANTAGES
Sika® Set Accelerator is a calcium-chloride based ad- The advantages of Sika® Set Accelerator are:
mixture used to reduce the setting time of concrete. ▪ Reduced initial setting time of concrete.
▪ Improved early strength development of concrete.
USES ▪ Reduction of delays due to cold weather.
▪ Reduction of concrete bleed (due to faster set)

▪ Improve setting time and early strength for precast
concrete products.
Note: The use of Sika® Set Accelerator will increase
the calcium-chloride content of concrete. Precautions
must be taken to ensure the chloride content of rein-
forced or prestressed concrete does not exceed the
chloride limits imposed by AS 1379 and other relevant
construction standards.

Recommended Dosage Typical dosage is between 1000 and 2000 ml per 100 kg of total cementi-
tious material. Optimum dosage should be determined by site trials.
Dosages outside the typical range can be used. Trials should be carried out
to confirm performance.
As ambient and concrete temperatures reduce an increase in the dose rate
of Sika® Set Accelerator may be necessary in order to maintain perform-
ance.
At very low temperatures (typically below 5°C), other precautions may be
necessary in order to ensure concrete sets. Precautions may include heat-
ing water or aggregates etc.
Compatibility When using with other admixtures check compatibility first.
When using Sika® Set Accelerator laboratory and site trials are recommen-
ded.
Dispensing Sika® Set Accelerator should ideally be dispensed with the batch water.
Sika® Set Accelerator should not be dispensed directly onto dry cementi-
tious materials.
Sika® Set Accelerator can be added to concrete after mixing, but concrete
should then be thoroughly mixed before being discharged. (Minimum of 1
minute/m3 mixing at full speed).
