KingAdd 100LW®
Air enteraining agent for concrete.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingAdd 100LW is an air entraining admixture for concrete, formulated from selected polymers specially designed to create microscopic air bubbles that are uniformly distributed in the concrete mix. This effect can be used to improve concrete cohesion and resistance to freeze thaw cycles.
Where to use
- In concrete mixes for roadways, airport runways and other concrete exposed to potential frost damage.
- To increase the durability of concrete and its resistance to damage by frost and de-icing salts.
- To increase cohesion of concrete mixes to overcome bleed, segregation and sand runs where poorly graded aggregate with high fine content needs to be used.
Why use it
- Greatly improves cohesion, reduces segregation and bleeding.
- Increased freeze/thaw cycle resistance.
- Improves workability and plasticity.
- Exceptionally effective with aggregate with high fine content.
- Suitable for mixes containing PFA, GGBS and microsilica.
- Chloride free.
COMPATIBILITY
KingAdd 100LW can be used with all types of Portland cement and cement replacement materials.
KingAdd 100LW is compatible with other KINGKRETE admixtures used in the same concrete mix.
If more than one type of admixture is to be used in concrete mix, they must be dispensed to the concrete separately.

DOSAGE
The guidance dosage of KingAdd 100LW to achieve air content of 5 ± 2% in the concrete mix is 0.10 - 0.30 liters/ 100 kg of cementitious material in the mix, including GGBFS, PFA or microsilica.
Representative trials should be conducted to determine the optimum dosage of KingAdd 100LW to meet the performance requirements by using the materials and conditions in actual use
Points to be considered that affecting air entrainment
Any variation in the following factors will cause change in the air content:
- Cement fineness.
- Concrete temperature.
- Sand grading.
- Mixture types.
- Compaction method.
- Carbon or organic impurities
Effects of Over Dosage
Over dosage of KingAdd 100LW will cause the following:
- Significant increase in air content which may cause slight reduction in the compressive strength.
- Slight increase in setting time.
Standards and approvals
KingAdd 100LW complies with ASTM C260.
How to use
Method of use
KingAdd 100LW should be added to the concrete with the mixing water to achieve optimum performance.
Automatic dispenser should be used to dispense the correct quantity of KingAdd 100LW to the concrete mix.
Cleaning
KingAdd 100LW can be washed with fresh cold water.
Coverage, packaging and storage
Packaging
KingAdd 100LW is available in 25 liters pails, 210 liters drums and 1000 liters bulks supply.
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
Health and safety
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs. Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation.
