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)
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.
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.
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.
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.
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.
