  • Increased workability with reduced water
  • Flowing yet very cohesive
  • Easy to pump
  • High early strength due to high water reduction
  • Chloride free
  • Add POLYTANCRETE SPR to the pre-wetted concrete mix at a rate of 0.8 to 1.2% by weight of a binder
  • Actual site trials have to be carried out to minimize the optimum dose for the intended application
  • Mix the measured quantity of POLYTANCRETE SPR with part of the gauging water and then add to the mix
POLYTANCRETE NGT: Superplasticising admixture

In plastic concrete:

  • Improves workability
  • Reduces segregation and water requirements In hardened concrete
  • Increases strength
  • Improves finished appearance
  • Reduces cracking and permeability
  • Conforms to ASTM C 494 type F & IS 9103 for chemical admixture
  • Reduce water-cement ratio while maintaining workability
  • Increases strength of the concrete/ mortar by reducing water content
  • It is soluble
  • Add it to the gauging water
  • It is desirable to have trial mixes to assess the actual effect of the ingredients under field conditions
  • Always use measured quantities
POLYTANCRETE HP: High range water reducing PCE based concrete admixture
  • Hyperplasticizer in the production of free-flowing concrete for all precast and RMC concrete slabs
  • Foundations, walls, columns, piers, high-strength concretes, etc
  • Reduced water/cement ratio while maintaining workability
  • Improved placeability in slender components with packed reinforcements
  • Decreased need for extensive vibration for compaction
  • Compatibility with standard plasticizers and retarders for synergized mixes
  • High early strengths for precast or early stripping
  • POLYTANCRETE HP is water soluble and should be added to the gauging water used in concrete/mortar mixing.
  • Add 500-1500 ml of POLYTANCRETE HP per 100 kg of cementitious material, depending on the desired slump or workability of the concrete.
  • Conduct trial mixes to determine the optimal dosage and observe actual effects in field conditions.
  • Due to variations in materials, job site conditions, and applications, dosages outside the recommended range may be necessary.
  • Effects of overdosage include: extended initial and final set times, mix bleed/segregation, quick loss of workability, and increased plastic shrinkage.
POLYTANCRETE SF: Superplasticiser for self-compacting concrete (SCC)
  • Precast and ready-mix concrete
  • Safe for use in prestressed and reinforced concrete
  • Hot weather concreting where rapid slump loss occurs
  • High-performance concrete
  • Produces self-compacting concrete
  • Flowing yet very cohesive concrete is produced without bleeding and segregation
  • It can be pumped easily
  • High early strength due to high water reduction of up to 30-40%
  • Improves impermeability and durability
  • Add POLYTANCRETE SF to the pre-wetted concrete mix at a rate of 0.4 to 0.8 %
  • Add it to the weight of cementitious material
  • Mix the measured quantity of POLYTANCRETE SF with the remaining 10-20 % of the gauging water
  • Then add it
How do you fix concrete that looks bad?

To fix concrete that looks bad, clean the surface thoroughly, addressing stains or discoloration. Repair cracks with filler, resurface damaged areas, and consider applying a concrete overlay for a fresh appearance. Staining or painting the concrete and adding decorative elements can also enhance its aesthetic appeal, providing a cost-effective improvement.

Can I repair concrete myself?

Yes, you can repair concrete yourself for minor issues. Patching small cracks or holes with a concrete patching compound and using epoxy or polymer-based resurfacers for surface repairs are common DIY solutions. However, for significant damage or structural issues, consulting a professional is recommended for proper assessment and repair.

Does concrete repair last?

The longevity of concrete repair depends on the extent of the damage, the repair method applied, and the quality of materials used. When done correctly, concrete repairs can last for an extended period, providing durability and restoring the structural integrity of the surface. Regular maintenance can further extend the lifespan of the repair.

Are concrete Admiture expensive?
Concrete admixtures’ costs can be quite diverse, ranging from affordable to premium. Basic water reducers or workability enhancers might cost just a few cents per liter, while specialized high-performance admixtures for extreme conditions can reach several dollars. Ultimately, the “expensiveness” depends on the specific admixture type, desired properties, and project scale. Remember, a small amount can significantly impact concrete performance, often outweighing the initial cost in terms of saved time, material, and labor.
Does Admixture affect the strength of concrete?
Yes, admixtures play a role in concrete strength, but it’s a nuanced relationship! Some, like superplasticizers, allow the reduction of water while maintaining workability, leading to denser, stronger concrete. Others, like pozzolana, react with cement to fill void spaces, also boosting strength. However, not all admixtures are strength-boosters. Some retard setting or improve workability in specific ways, impacting strength indirectly. It’s crucial to choose the right admixture for your desired outcome and follow dosage recommendations for optimal strength and performance.
