Polycarboxylate Superplasticizer

Description

Polycarboxylate Superplasticizer is a new generation superplasticizer based on modified polycarboxylate particularly recommended for ready mixed concrete and civil engineering construction. Its particular configuration allows its delayed adsorption onto the cement particles and disperses them efficiently.

Standard Compliance
Polycarboxylate Superplasticizer complies with the requirements of the following standards: ASTM C 494, Type F,G and E. BS EN 934-2.

Uses
■ To obtain a high quality concrete mix with accelerated strength development and extended workability without delayed setting characteristics.

■ To provide a concrete mix with exceptional placing characteristics and accelerated cement hydration for early strength development and high quality concrete.

■ To provide improved durability by increasing ultimate strengths and reducing concrete permeability.


Typical Applications & Advantages
■ Provides high quality durable concrete.

■ Powerful plasticizing action with an improved initial workability, easier placing and faster strength development.

■ Reduce water cement ratio to the maximum which allows production of high strength concrete.

■ Capability of delivering high performance concrete at any time to the job site in place.

■ It can be either used alone or after compounded with other additives to make special concrete such as pumping concrete, ready mixed concrete etc. 


Technical Support and Services
MUHU offers one-stop type services and turn-key project.

The system adopts heatless production instead of traditional heating source, which greatly reduces cost on related equipment and energy consumption. MUHU greatly improves the production formula and equipment to successfully obtain one localized production technology program, which takes closed production approach and has no waste discharge to the environment. Complying with the environmental protection requirements, the system has energy saving, high-level of automation, computer-precise control, low initial equipment investment, low production cost, convenient feeding, quick production, easy installation and maintenance, uniform mixing and easy operation (Just need 1-2 workers). Thus, the product from this system is more competitive. The system has the feature of low risk, but high capacity and high rate of return. It is one of the best production solutions. If the production can be localized, the cost can be reduced further from transportation and package. The product technology and the production equipment of this system have obtained the national patent in China.

Instructions for Use
Polycarboxylate Superplasticizer must preferably be added in the mixing water and in case of ready mixed concrete where the product can be added on fresh concrete and in a mixing truck. It is necessary to mix at a high speed for about 6 – 8 minutes.

Dosage
The optimum dosage of Polycarboxylate Superplasticizer to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use.

Setting
Polycarboxylate Superplasticizer affords excellent control over initial and final setting times. Setting times of concrete mixes are related to cement type, mix design, and ambient temperature.

Compatibility
Polycarboxylate Superplasticizer should not be used in conjunction with any other admixture unless prior approval is obtained from MUHU.

Packaging & Storage
■ Polycarboxylate Superplasticizer (PC-P) is packed in 25kg / drum.

■ Polycarboxylate Superplasticizer (PC-F/G/E) is available in 1100 kg / IBC tank , 240 kg / drum or flexitank. For site installations, deliveries will be made in bulk to site storage tanks.

■ Polycarboxylate Superplasticizer has a minimum shelf life of 12 months provided it is stored under cover, out of direct sunlight.

Health & Safety Precautions
Polycarboxylate Superplasticizer does not fall into the hazard classifications of current regulations. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable protective gloves and goggles should be worn. Splashes on the skin should be removed with water. In case of contact with eyes rinse immediately with plenty of water and seek medical advice. If swallowed, seek medical attention immediately and do not induce vomiting.
