Exilva: Performance as Yield Stress Enhancer

Demonstrations at our concrete laboratory show the performance of Exilva® as a yield stress enhancer in concrete. We used a typical mix design for a standard mortar to simulate concrete performance.

Using Exilva as a viscosity modifying agent (VMA) in mortar and concrete can improve viscosity significantly without making the concrete or mortar sticky. The viscosity effect depends on dosage. A typical range of active Exilva dosage is 0.25% to 5% liquid by weight of cement.

Key takeaways:

• 21% to 38% improvement in yield stress vs. cellulose ether
• Significantly reduced risk of segregation and bleeding
• Works across all water to cement ratios (w/c)
