Polycarboxylate Superplasticizer Ether

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.

Typical Properties

Uses of Polycarboxylate concrete admixture:

■ 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 of Polycarboxylate concrete admixture:

■ Provides high-quality durable concrete.

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

■ Reduces water/cement ratio to the maximum that allows for the production of high strength concrete.

■ Capability of delivering high performance concrete at any time to a job site.

■ Polycarboxylate Concrete Admixture can be either used alone or 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 projects.

Our system adopts heatless production instead of using traditional heating sources resulting in greatly reduced costs for equipment and energy consumption. MUHU greatly improved the production formula and equipment to successfully obtain one localized production technology program utilizing a closed production approach with no waste discharge to the environment. Besides complying with environmental protection requirements, the system has energy-saving, high-level automation, computer-precise controls, low initial equipment investment, low production costs, convenient feeding, quick production, easy installation and maintenance, uniform mixing and overall easy operation (Only 1-2 workers required). Results are the products from our system are highest efficiency and more competitive. This system has the feature of low risk with a very high capacity and 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. Our product technology and the production equipment of this system have obtained numerous national patents in China.

Instructions for Use

Polycarboxylate Superplasticizer must preferably be added to 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.

Dosages outside the normal range quoted above can be adopted to meet particular mix requirements.
Contact MUHU for advice in these cases.

Setting

Polycarboxylate Ether 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 / bag.
