MVN - SR
HIGH RANGE WATER REDUCING ADMIXTURE
DESCRIPTION:
MVN-SR is a 3rd generation, high performance polymer based superplasticizer for producing soft consistency high grade concrete.
MVN-SR meets the requirements of TCVN 8826 and ASTM C494 type D&G
USES:
MVN-SR mainly suitable for the manufacture of concrete for ready-mix concrete and precast batching plants. MVN-SR is used for the following types of concrete:
● Bored piles
● Foundation
● Pavements (taxiway, runway, concrete roads)
● Barrette foundations and diaphragm walls
● Walls, columns, beams
● Concrete slabs in buildings and workshops
CHARACTERISTICS – ADVANTAGES:
MVN-SR combines different types of effects, such as electrostatic and steric effect. The polymer molecules adsorb onto the surface of fine particles, keeping them apart while hydration progresses, MVN SR effects the following concrete properties:
● Improves the cohesion of mortar phase
● Long slump keeping and high water reduction
● High workability - minimizes placing and compacting effort
● Faster evolution of strength development
● Workability can be maintained up to 2 – 3 hours
● Mitigates the effects of creep and shrinkage in concrete
APPLICATION INFORMATION
Recommended dosage: 0.6 to 1.6 L per 100kg cement/ binder
Typical dosage: 1.0 to 1.4 L per 100kg cement/ binder
Overdosing will result in increased workability and setting time of the Concrete, however, provided that curing is effective, ultimate concrete strength and properties will not be affected
TECHNICAL INFORMATION
MVN-SR can be added directly to the pre-measured water and then added to the dry concrete mix or added separately to the wet concrete mix. To achieve the best effect of the admixture, the mixing time must be at least 60 seconds from the time the MVN-SR mixture is added to the batch.
Mixing, Placing and Handling: With the use of MVN-SR, concrete of highest quality is being produced, however requires strict adherence to concrete technology processes such as mixing, placing, compacting and proper curing.
Compatibility: MVN-SR is compatible with most Portland cements. MVN-SR is compatible with MVN-WPA (waterproofing admixture), Elkem microsilica (mineral admixture) and other MVN superplasticizers. Not compatible with Naphthalene-based agents.
