Applications

In principle, Celitements can be used in all areas of application known from traditional portland cement. Celitement is, however, not a binder as defined in the European cement standard EN-197. Nevertheless, Celitements can be stored, transported and processed like classical cement.

The cement stone/matrix formed when using Celitements, in other words the “glue” in modern mortars and concretes, largely corresponds to the known end products (known as the C-S-H phases) from the hydration of the classical Portland cement clinker phases such as C3S (alite) and C2S (belite). For use in constructive concrete, however, strict normative and building regulation rules must be complied with. Up to now, Celitement is not a standardised material however. Nevertheless, many different types of concretes have already been manufactured on a trial basis using Celitement. Fresh concrete properties, physical data of hardened concrete and data on durability are therefore available. Despite that, no constructive concrete components containing Celitements can actually be used in practice without a national or European approval. The amount of test material that we are able to manufacture in the pilot plant, is not sufficient in any case for large scale concrete works. But quite apart from an intended use in readymix concrete or the field of prefabricated concretes in the future, there are numerous other potential areas of application with much lower normative or building regulations restrictions for immediate practical use of innovative binding agents such as Celitement. We have gained a wealth of experience from testing Celitement in a total of 14 selected fields of application together with our partners (“innovators”) in recent years.

As a pure calcium hydrosilicate, the interactions with the very high-performance construction chemical additives of modern material recipes can in most cases be adapted.

The first practical experience of the processing of Celitements, however, shows that effective use is possible in many applications even when using typical established construction chemicals and branded products.

If variants of well tried and proven construction chemical additives are adapted to Celitements in the future, this could lead to significant additional performance gains and offers great potential. In order to do this, we are working together with well-known collaboration partners from construction chemistry.
Critical to the success of modern “formulated” material systems is the joint consideration of all the interactions between the different ingredients in the planned application.

Almost all of the sometimes very ambitious applications of modern mortars or concretes, use construction chemical additives. The coordination between construction chemistry and binding agents requires a large amount of research, development and consultation effort from both, the manufacturers of construction chemicals and auxiliary substances and from the producer of hydraulic binding agents. This applies in particular when construction chemical additives are needed for entirely new and very innovative material combinations or recipes. This is also the case when using Celitements. Just like when using classic cements, the performance of Celitement in different fields of application varies significantly depending on the skill and the inventiveness of the technology and application engineers combining the materials.

Celitement GmbH can provide valuable support on this. The performance of products based on Portland cement can normally also be achieved with Celitements. In some cases this can even be exceeded or entirely new combinations of known properties are made possible. It is, however, always a technical challenge to achieve or exceed the performance of recipes for complex material systems based on many years of experience with Portland Cement, when using entirely new binding agents.
