Economical & environmentally friendly

Economic viability

The intensive use of air traffic surfaces and motorways allows no practical time for longer closures for urgently needed repair work. Associated loss of use causes enormous problems for the operators and consequently results in high costs. The rapid-hardening concrete Concretum® Q-FLASH 2/20 offers an economic solution for this: The reconstruction work can be performed in very short periods of closure during phases with limited traffic volume, e.g. at night.

Concrete pavements, which are made with Concretum® rapid-hardening concrete have a maintenance-free lifespan of more than 40 years, which is much longer in comparison to that of asphalt transport surfaces. In large-scale applications, the costs for Concretum® Q-FLASH 2/20 are also comparatively low.
As a result, this solution is becoming the most economical method for reconstructing concrete transport surfaces.

Like standard concrete, Concretum® Q-FLASH 2/20 is also characterised by high levels of rigidity and strength compared to asphalt. This allows the required load-bearing behaviour to be achieved with a small slab thickness. This also contributes to economic construction methods.

Concretum® Q-FLASH 2/20 is produced like standard concrete in a concrete plant. As a result, the regionally available infrastructure is used and transport distances for the concrete are low.

Environmental compatibility

The rapid-hardening concrete Concretum® Q-FLASH 2/20 is an environmentally friendly product for the reconstruction of concrete transport surfaces.

As a result of its long, maintenance-free lifespan, environmental impacts of repair and reconstruction work are avoided. Its environmental compatibility is therefore better than that of asphalt, whose lifespan is shorter.

At the end of its lifespan, rapid-hardening concrete can be fully recycled without restrictions, in contrast to asphalt. This therefore creates a closed construction material circle. Space for dumping is not required.

Energy consumption and CO2 emissions during production and hardening of the rapid-hardening cement used in Concretum® Q-FLASH 2/20 are approximately one third that of standard Portland cements. The reason for this is differences in the mineralogy and the lower firing temperatures.

The main components of the rapid-hardening concrete are purely mineral and are available regionally. This distinguishes the rapid-hardening concrete favourably when compared to asphalt with its oil-based bitumen binder.
