Working with rapid-hardening concrete

Our experienced engineers support you when choosing the concrete batch plant, when developing your concrete mix design, with all necessary work preparations.

Certain preparations and preliminary tests are needed to ensure optimum use of our rapid-hardening concretes. Tests are performed in our laboratory and in the commissioned concrete batch plant as a first step in order to determine a precise and project-specific concrete mix design. A sample slab can then be produced under real conditions – ideally at a location where there is no risk to operation. If the attempt was successful, the process of replacing the slabs on the operating surfaces commences.

Precise planning of all work steps is critical for successfully pouring rapid-hardening concrete. As soon as the first meters of a concrete pavement are filled with concrete, compacting has to commence straight away – even if the concrete for the next part of the same slab is not yet at the construction site. This subsequent casting process represents the major difference to working procedures for conventional concrete.

The right rapid-hardening concrete for your construction project

Use of a slipform paver for pouring the concrete is generally a good solution for larger reconstructions and repairs. Runways and landing strips, for example, can therefore be completely reconstructed within one construction season – and always overnight. Repairs to motorways and airport pavements are therefore possible without interrupting operation. Our rapid-hardening concretes can also be poured manually however. This is the case, for example, if the geometry of the renovation surface is challenging, the concrete slabs being replaced are not directly adjacent to each other or if the area to be replacement is too small for using a slipform paver efficiently. The consistency and working time of our concretes can be adjusted optimally to the needs of the construction site: with the correct admixture dosages, the rapid-hardening concrete allows project-specific requirements, such as transport distances, pouring times and methods as well as local conditions, to be taken into account at all times. The manual pouring method is characterised above all by its high flexibility and is used, in particular, for follow-up work.

Concretum is at your side as a competent partner throughout the entire construction project. Our experienced engineers support you, for example, when choosing the right concrete batch plant, when developing your concrete mix design and with all necessary work preparations. Optimum cooperation is therefore ensured between all participating companies. And: you can rely on us, supporting you with our unique products throughout all stages of your project.
