Concretum® Q-FLASH 10/20 is a rapid-hardening concrete. It is ready for reloading only ten hours after concrete mixing. Furthermore, Concretum® Q-FLASH 10/20 dries very fast which accelerates the concstruction process. Concretum® Q-FLASH 10/20 is produced in concrete plants.
Applications
All sorts of rapid-hardening concrete applications.
In general for casting concrete structures that dry extremely fast.
Maintenance and construction of concrete carriageways with very short off-times (roundabouts, bus stops etc.)
Screeds and repair of bridge floors.
Foundations, supporting members, bottom plates and floor slabs.
Replacement and maintenance of solid railway basements.
Production of precast concrete elements with short stripping times.
Material properties
Concretum® Q-FLASH 10/20 enables the production of concrete elements which feature a compressive strength fc of at least 20 N/mm² only ten hours after concrete mixing.
48 hours after mixing Concretum® Q-FLASH 10/20 arrives at a moisture content of 4.0 CM-%. This enables immediate subsequent applications such as sealings on bridgedecks or flooring systems.
The workability of Concretum® Q-FLASH 10/20 is good for at least 1.5 hours.
Concretum® Q-FLASH 10/20 features low shrinkage and low heat of hydration. Therefore, construction units made of Concretum® Q-FLASH 10/20 show low risk of cracking and are immensely durable.
Depending on the application, Concretum® Q-FLASH 10/20 can be reinforced by Concretum® SUPERFIBER. Please take notice of the product information on SUPERFIBER 40/8.
