KingMix 115SP®
High performance water reducing admixture for HSC.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingMix 115SP is high performance superplasticising admixture formulated from selected polymers specially designed to enable the water content of the concrete to perform more effectively.
This effect can be used in high strength concrete mixes to improve workability, to increase ultimate strengths or to facilitate a reduction in the cement content while sustaining and improving mix properties.
Where to use
- Recommended for high strength concrete mixes.
- Improved cohesion allows for use in mass concrete pours and filing.
- To produce high quality concrete of improved durability and water tightness.
Why use it
- Allowing for high strength concrete production without excessive cement contents.
- Improved workability reduces placing and compaction problems.
- Cement saving without affecting strength.
- Minimizing segregation and bleeding problems by improving cohesion.
- More durable concrete as a result of reduction in permeability and lower water to cement ratio.
COMPATIBILITY
KingMix 115SP can be used with all types of Portland cement and cement replacement materials. KingMix 115SP is compatible with other KINGKRETE admixtures 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.

DOSAGE
The guidance dosage of KingMix 115SP is 1.0 - 2.8 litre per 100 kg of cementitious materials in the mix, including GGBFS, PFA or micro-silica.
Representative trials should be conducted to determine the optimum dosage of KingMix 115SP to meet the performance requirements by using the materials and conditions in actual use.
EFFECTS OF OVER DOSAGE
Overdosing of KingMix 115SP will cause the following:
Significant increase in retardation.
Increase in workability.
Ultimate concrete strength will not be adversely affected and will generally be increased provided that proper concrete curing is maintained.
SETTING TIME
Although the setting time is dependent on the dosage of KingMix 115SP, the following factors should be considered:
- Retardation is increased with lower levels of tri- calcium in the cement.
- Lower temperatures will delay the setting time.
- SRC cement gives higher retardation level than ordinary cement.
- Using more than one type of admixture in the same concrete mix could affect the setting time.
- Retardation level is increased when cement replacement materials are used in the concrete mix.
Standards and approvals
KingMix 115SP complies with BS EN 934-2:1998 and ASTM C494, Type G.
How to use
Method of use
KingMix 115SP should be added to the concrete with the mixing water to achieve optimum performance. An automatic dispenser should be used to dispense the correct quantity of KingMix 115SP to the concrete mix.
Cleaning
KingMix 115SP can be washed with fresh cold water.
Coverage, packaging and storage
Packaging
KingMix 115SP is available in 25 litre jerrycan, 210 litre drums and 1000 litre 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.
