CEMWET SP -3000 (PCE)

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 (PCE) disperses cement particles and can maintain slump of concrete for more than two hours without affecting early development of strength.

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

DOSAGE :
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.

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

TYPICAL PROPERTIES

Colour : Light Yellow
Specific Gravity : 1.15 ± 0.020
Chloride Content : NIL to BS 5075 to IS 456-2000
Air Entrainment Water Reduction : Maximum 1.5% of control as per I.S.: 9103-99
Water Reduction : More then 35%
Flow Characteristics : Only a small amount of additive is needed to improve the flow of concrete. At low water to cement Of Fresh Concrete           ratio, the concrete is capable to flow and remains mobile normally one to two hours without adding                                     any more water or additives.

Compressive Strength : By Designing concrete mixes admixed with the admixed with the admixture and water reduction upto 30% and cement conten ranging from 180 to 450 kg/m3, it has been possible to reain slump of cencrete up two hours and achieve high early and long term strength. However, the composition of cement, type and grading of san, dosage of the admixture and the water reduction are the important factors that play part in designing the concrete mixes and should be considered for achieving plasticity, durabiliyt and hight strength of the concrete.

EFFECTS OF OVER DOSAGE :

• Retardation of initial and final set
• Slight increase in air entrainment
• Increase in workablity

SAFATY PRECAUTIONS :

CEMWET SP-3000(PCE) CONTAINS NO HAZARDOUS SUBSTANCES.

STORAGE :

CEMWET SP-3000 (PCE), IN tightly closed contains, has a shelf life of at least 2 years. The product must be stored in aplace where temperatures do not drop below +50c. if the product has frozen, thaw and agitate until completely reconstituted.
