Concretum® Q-CON is a rapid-hardening dry and repair concrete with a maximum aggregate size of 16 mm. The concrete can be fully loaded just 2 - 2.5 hours after mixing. Additionally, Concretum® Q-CON dries very quickly, significantly accelerating construction progress.
Q-CON is very easy to use: the dry concrete is available in bags and is simply mixed with clean tap water in a construction mixer. This makes Q-CON especially suitable for local repairs and maintenance such as deep edge breakages or large joint repairs – whenever quick strength is required.
Furthermore, Concretum® Q-CON dries extremely fast, greatly speeding up construction progress. Thanks to its properties, for example, sealings in bridge construction can be applied after a very short time. Concretum® Q-CON is characterized by a particularly low shrinkage rate, making the components created with this repair concrete highly durable.
Advantages and Features:
- Concretum® Q-CON allows the production of concrete elements that already achieve a compressive strength (fc) of 20 N/mm² just two to two and a half hours after mixing the concrete.
- After approximately 3 hours, Concretum® Q-CON reaches a moisture content of less than 4.0 CM-%. This enables further work steps, such as the application of sealants in bridge construction or floor installations.
- Depending on temperature and the amount of water added, Concretum® Q-CON remains workable for 45-75 minutes.
- Concretum® Q-CON is characterized by a low shrinkage rate. As a result, components made with Concretum® Q-CON have a very low tendency to crack and are therefore exceptionally durable.
Depending on the application, Concretum® Q-CON can be reinforced with Concretum® SUPERFIBER. Please refer to the product information for Concretum® SUPERFIBER fibers.
