CEMWET SP - 3000(SR)

SLUMP RETAINING SUPER PLASTICIZER FOR SELF-COMPACTING PLASTIC CONCRETE

DESCRIPTION :

CEMWET SP-3000 (SR) is a Fourth Generation Super Plasticizer having high molecular weight. The product is sulphonated polymer made by modifying Naphthalene Formaldehyde condensate which allows mixing water to be reduced considerably maintaining slump of concrete for longer period of time as compared to normal Naphthalene and Melamine polymer condensates. CEMWET SP -3000 (SR) is a chloride-free product having prestigious mark of IS 9103-99. The admixture produces self-compacting or self-leveling concrete with high slump retention. The product is high quality admixture produced by maintaining stable quality control and is provided with performance assurance certificate whenever required.

PRIMARY USES :

• In concrete mixes, that are workable with less water for achieving high strength and high performance concrete.
• For production of plastic and self-compacting concrete.
• Suitable for Ready-Mixed Concrete and pre-cast concrete mixes.
• Improves performance of Low water cement ratio concrete and its Stump retention is increased to more than two hours.
• Suitable for high C3A and high fineness OPC cement.
• Suitable for Slag Cement having very high fineness.
• Excellent performance in concrete mixes used for bridges, high rise buildings, Off-shore and marine structures, pe-cast and prestressed structures, tunnels etc.

SPECIALITY

• CEMWET SP-3000 (SR) disperses cement particles and can maintain slump of concrete for more than two hours without affecting early development of strength.
• CEMWET SP-3000 (SR) satisfies ASTM C-494 Type-G at normal Dosage. Dug to high water reduction capacity of more than 35% all the properties of hardened concrete are improved significantly, namely, shrinkage, creep, work oility & modulus of elasticity.

CEMWET SP 3000 (SR) is compatible with all types of cements.

• OPC especially high C3A (>8) and high fineness cement (>2700 cm2/gm) viz - OPC-43 and 53 Grade Cement etc.
• OPC Low C3A cement, Sulphate Resistant Cement, Pozzolana cement.
• High Alumina Cement Concrete
• Slag Cement

Recommended dosage is 0.3% to 2.5% by wt. of cement. However accurate dosage can be determined after laboratory trials for a particular concrete mix design.

250 Kg. drums. Bulk deliveries in tankers are available on request.

Colour : Brown Free Flowing Liquid

Specific Gravity : 1.22 ± 0.020

Chloride Content : NIL to BS 5075 to IS 456-2000

Flow Characteristics Of Fresh Concrete : Only a small amount of additive is needed to improve the flow of concrete. At low water to cement ratio, the concrete is capable to flow and remains mobile normally one to two hours without adding any more water or additives.

Air Entrainment : Max. 1.5% of control as per I.S.: 9103-99

Water Reduction : More then 35%
