Concretum® Q-FLASH 5/20 is the light version of our rapid-hardening concrete Q-FLASH 2/20 – designed for situations where extreme speed is not required, but a rapid construction progress is still essential. Depending on the construction situation and requirements, the high-tech concrete can be processed between 1.5 and 3 hours. It is fully load-bearing just 5 hours after production. Thanks to the use of rapid-hardening cement, Q-FLASH 5/20 is not only highly durable and easy to produce and apply, but it is also cost-effective. The production takes place in the concrete plant.
Advantages and Features:
- Rapid strength development (compressive strength fc > 20 N/mm² after 5 hours)
- Extremely fast drying (< 4.0 CM-% after 6 hours)
- Cost-effective - easy to produce and apply
- Consistent consistency throughout the open time (up to 180 minutes)
- Fresh concrete temperature range: 5 – 30 °C
- Winter concrete - Rapid strength development and quick drying even at very low temperatures
Applications:
- Traffic areas – Short closure times, quick reopening (weekend closures), and no exposure to de-icing salts
- Bridge construction – Various components with short formwork removal times
- Track construction – Replacement of solid roadbeds in railway tunnels
- Building construction – Various components with short formwork removal times, waterproofing for flat roofs, ceilings, and floors
- Civil engineering – E.g., all types of components that need to harden quickly or dry rapidly
- Tunnel construction – Various components in tunnel construction
