Introduction of polycarboxylate superplasticizers

Key words :

  1. polycarboxylate superplasticizer
  2. Polycarboxylate concrete
  3. polycarboxylate ether
  4. polycarboxylate ether superplasticizer

Description

Polycarboxylate superplasticizer is a new generation of water-reducing agent based on modified polycarboxylic acid, which is especially recommended for ready-mixed concrete and civil engineering. Its special structure ensures delayed adsorption and effective dispersion of cement particles.

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 improved initial workability, easier installation and faster strength development.
  • Reduce the water-cement ratio to the maximum value that produces high-strength concrete.
  • Possibility of delivering high performance concrete to the construction site at any time.
  • It can be used alone or in combination with other admixtures to prepare specialty concrete such as pump concrete, ready-mixed concrete, etc.

Technical Support and Services Instructions for Use

It is recommended to add polycarboxylate water reducing agent to the mixing water. For ready-mixed concrete, this product can be added to fresh concrete and concrete mixer trucks. It takes about 6-8 minutes to mix on high speed.

Dosage

The optimal amount of polycarboxylate superplasticizer to meet specific requirements should always be determined by testing with materials and conditions that will be verified in use.

Dosages outside the above normal range may be determined according to the specific requirements of the mixture.

In this case please contact Dongke Group for advice.

Setting

Polycarboxylate superplasticizers provide excellent control over initial and final setting times. The setting time of a concrete mixture depends on the cement type, mixture composition and ambient temperature.

Compatibility

Polycarboxylate superplasticizers may not be used in combination with other additives without prior approval from Dongke Group.

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 superplasticizers do not fall into the hazardous classifications of current regulations. However, it should not be swallowed or allowed to come into contact with skin or eyes. Suitable protective gloves and goggles must be used. Splashes on skin should be removed with water. In case of contact with eyes, rinse immediately with plenty of water and consult a physician. If swallowed, seek medical attention immediately and do not induce vomiting.
