Flugasche nach DIN EN 450-1 ist ein feinkörniger mineralischer Zusatzstoff, der beim Verbrennen von Steinkohle entsteht. In der Betonherstellung wird sie als sogenannter Typ-II-Zusatzstoff eingesetzt, um die Verarbeitbarkeit, Dauerhaftigkeit und Umweltbilanz von Beton zu verbessern. Damit Flugasche im Betonbau eingesetzt werden darf, muss sie den Anforderungen der europäischen Norm DIN EN 450-1 entsprechen. Diese Zertifizierung stellt sicher, dass die Flugasche konstante Qualität aufweist, keine schädlichen Stoffe enthält und die bauphysikalischen Eigenschaften des Betons zuverlässig unterstützt.

The topic of fillers describes the wide range of substances that are added to mortar systems to generate various effects. This can include weight reduction through lightweight fillers, water retention, binder replacement, improvement of the CO2 balance and much more. We would be happy to check whether we can offer or suggest something suitable for your topic.
Our Compund is based on polycarboxylate and is particularly suitable for use in cement screeds.
It is used in 1K products, i.e. in powder form. The advantage is that it requires much less dosing than conventional superplasticizers. If you are interested and for further information, please Contact us.

Internal curing describes the topic of optimally supplying the cementitious binder with water during the setting process. For this purpose, so-called internal curing compounds are used, i.e. additives that retain water for a later point in the setting process. For further information, please Contact us.

Manganese oxide is a finely ground manganese ore with a very high content of MnO2, which is insoluble in water and solutions. For further information please Contact us.
Microcracking is a common problem in mortar systems that occurs due to the hydration process of the cementitious binder. One way of counteracting this is the use of microfibers, which act as a kind of reinforcement. We offer you a selection of different fibers for this topic, please Contact us.
Micro fibers are plastic fibers with a cut length between 4 mm and 18 mm. Our range includes PP, PAN and polyamide fibers. For further information please Contact us.

Polyamide fibers are very fine fibers with high elasticity and are mainly used to reduce shrinkage cracks in the setting process of mortar systems. In contrast to PP and PAN fibers, they are hydrophilic and can therefore be mixed in very well and homogeneously without forming nests. For further information please Contact us.
We are pleased to present a new type of machine that is used to form aerated concrete or foam concrete. The special feature: The machine is just the size of a suitcase and therefore very easy to transport and very easy to use. We would be happy to put you in touch, we can highly recommend this contact.

TiO2 stands for titanium dioxide, which is typically used as a white pigment. Our products are a rutile form. They are manufactured using a typical sulphate method with classic surface treatment with Al and Si. The surface treatment improves the resistance and dispersion under the given conditions. Titanium dioxide is insoluble in water and organic solutions. Titanium dioxide is very stable and chemically inert. If you are interested in this topic, please contact Contact us.

Ultramarine Blue is part of our small but fine selection of pigments for use in hydraulically bound systems. Contact us.
Water retention is a common issue in mortar systems. If too little water is available when the mortar is mixed, the cement paste that has formed dries and forms a solid skin around the cement core, which has not yet reacted. The result is that the required final strength is not achieved and the system suffers. For this purpose, natural substances are used which absorb water in order to release it into the cement matrix at a later stage and thus achieve an optimum result. For further information, please contact Contact us.
We offer two different forms of natural zeolite, a clinoptiolite and a natrolite. Both are used for various purposes, including as an internal curing compound, as an ion scavenger, light filler and, in special applications, as a substitute for binders. For specific information, please Contact us.
Optimizing the CO2 balance of cementitious products is a common topic. We offer you a product that can be added to the cement content and thus has a positive effect on the CO2 balance.
