KingMix 100SC®
Liquid concrete accelerator.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingMix 100SC is a set accelerating, chloride free admixture used for sprayed concrete, shotcrete and gunite processes.
Why use it
Rapid set allows thick sections to be built-up.
- Minimum rebound.
- Single pass spraying for thick layers.
- Excellent for overhead applications.
COMPATIBILITY
KingMix 100SC can be used with all types of Portland cement and cement replacement materials.
KingMix 100SC is compatible with other KINGKRETE admixtures when used in the same concrete mix. If more than one type of admixture is to be used in the concrete mix, they must be dispensed to the concrete separately.

DISPENSING AND MIXING
KingMix 100SC is normally introduced directly after the air ring in the spray nozzle. In order to obtain a consistent supply of admixture at the nozzle the delivery system should have a 600 KPa pressure pot, and a 20 mm inside diameter pressure delivery hose controlled by a pressure restrictor and tap.
With ‘wet process’ the use of a water reducing admixture to reduce the water content while increasing workability of the mix is recommended.
How to use
Method of use
Stiffening occurs approximately after 10 seconds of mixing concrete with KingMix 100SC. As with all other processes and products, the rapid initial acceleration of the cement hydration process, will affect the ultimate concrete strength.
Dosage
The optimum dosage for KingMix 100SC 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 KingMix 100SC is 5.0 - 20.0 liter/100 kg of cementitious and cement replacement material, including PFA, GGBFS or microsilica, which can be used as a starting point for the trials.
Use at Other Dosages
Dosages outside the typical range quoted above may be used if necessary to meet particular mix requirements. Compliance with requirements must be assessed through trial mixes. For further information and support, contact KINGKRETE Technical Staff.
EFFECTS OF OVER DOSAGE
An overdose of the intended amount of KingMix 100SC will result in reduced setting of the mix and will result in some loss of strength.
Cleaning
KingMix 100SC can be washed with fresh cold water.
