Description
MC-Super 43 is a concrete superplasticizer and retarder based on modified naphthalene sulphonate.
Where to use
Recommended where initial retardation of setting is required or desired. Improves performance in prestressed, precast and flowing-concrete applications. May be used with air-entraining cements and air-entraining admixtures where air-entrained concrete is specified or desired. When used with another admixture, each admixture must be dispensed separately into the mix.
Standards / source references
ASTM C-494 Type G · BS 5075
Advantages
• Improves workability without increasing mixing water. • Helps place heavily reinforced sections with reduced risk of honeycombing. • Allows reduction of mixing water while maintaining workability. • Retards initial setting, extending working time and improving concrete uniformity. • Promotes early strength development. • Increases compressive and flexural strength. • Improves resistance to surrounding and weather conditions.
Dosage / method
MC-Super 43 may be added directly to the mixing water before it enters the mixer, or separately to freshly mixed concrete. Use at 1000 ± 250 ml per 100 kg of cement. Determine the optimum dosage by trials using the same materials intended for use.
Cleaning
Clean tools and equipment with water.
Compatibility
Compatible with all types of Portland cement. Compatible with other MC-Admix products; each admixture must be added separately.
Storage / shelf life
18 months under suitable storage conditions in closed drums or tanks.
Safety
Non-toxic and nonflammable according to the approved source. Wash skin contamination with water. Standards ASTM C-494 Type G · BS 5075
Packaging
210 L drums and large-capacity tanks.
