Development of environmentally appropriate and sustainable product systems

No innovation has ever simply appeared from nowhere

There are more than 80 specialists in our research and development departments working on innovative environmentally-friendly resource-saving product systems for the protection and preservation of structural components and buildings.

Remmers has already implemented innovative ideas in successful products in many funding projects. One excellent example here is the model project ‘Protection of stone surfaces by applying elastic silicic acid ester’ (Federal Foundation for the Environment (DBU), Osnabrück, AZ 09445).

Remmers is also a project partner in many national and European funded projects:

  • BMBF-Project 'HelioClean'
  • BMBF-Project 'Cold ceramics'
  • BMBF-Project 'NanoLambda'
  • EU-Project '3Encult'

BMBF-Project - FKZ: 03X0069C

The HelioClean® project is part of the ‘high-tech strategy’ of the Federal Ministry of Education and Research (BMBF) within the framework program "Materials Innovations for Industry and Society - WING" about the topic of "Nanotechnology in the construction sector - NanoTecture: Promotion of the development of higher resource/energy-saving and performance potential as well as new functions, managed by the project owner Jülich (PTJ).

Project partners: Kronos International Inc., Remmers GmbH, IBU-tec GmbH, Dyckerhoff AG, Erlus AG, Leibniz University of Hanover, Technical University of Dresden, University of Kassel

Content of the three-year project is the catalytic decomposition of air pollutants using sunlight by means of nanotechnologically functionalized construction material surfaces. One positive side effect of the functionalization is a self-cleaning process that prevents the creation of biofilms and the connected bio-corrosion of building materials.

HelioClean® has an interdisciplinary structure and bundles the competences of three universities and five industrial partners (see affiliated partners). The tight network of university-based and industrial research aims to clearly improve the efficiency of a photo-catalyst, also in areas with poor light, and increase the effective surface of the photo-catalyst in the construction materials matrix. The ultimate aim is to create building materials and construction chemical products whose performance far exceeds existing products at a low price.

Within the scope of the HelioClean® project, the company Remmers GmbH has the task of developing a functionalized coating with mush higher efficiency with respect to the removal of air pollutants. The useful result can be seen on the motorway A1 near in the photocatalytic highly active coating ‘Remmers HC NOX’.

BMBF-Project - FKZ: 03X0067C

The ‘Cold ceramic’ project is part of the ‘high-tech strategy’ of the Federal Ministry of Education and Research (BMBF) within the framework program "Materials Innovations for Industry and Society - WING" about the topic of "Nanotechnology in the construction sector - NanoTecture: Promotion of the development of higher resource/energy-saving and performance potential as well as new functions, managed by the project owner Jülich (PTJ).

Project partners: BASF SE, Remmers GmbH, Woellner GmbH & Co KG, Betonwerke Neu-Ulm GmbH & Co KG, Chemiewerk Bad Köstriz, Association of German Cement Plants, Fraunhofer Institute for Silicate Research ISC, University of Kassel, FEhS – Institut für Baustoff-Forschung e. V., PigTek Europe GmbH

Content of the project is the development of chemically resistant and highly abrasion-resistant precast concrete products, concrete structures and coatings for the waste water field and other applications with very high chemical and/or mechanical loads (exposure classes XA3 and higher, XM3 and higher without additional measures; special applications) and particularly sustainable, low-energy and low-emission concrete buildings with a long life.

Important elements for achieving this goal include optimisation of the packing density down to the nanometre range by using specifically synthesized nano and micro particles. These are also chemically and technically modified so that they can be integrated specifically into the building material matrix. In addition, cinder sand slag is also used as a binding agent base that is excited with chemically-optimised alkali silicates (soluble glass). The resulting hydration products are lower in calcium than if portland cements are used, and the matrix is practically free of portlandite which leads to a much higher resistance to acid. The nano-crystalline SiO2 released when the cinder sand is excited with soluble glass leads to additional compaction of the microstructure in the lower nanometre range. Overall, extremely tight packing with a highly durable structure is achieved.

The entire value-creation chain of the developed cold-hardening ceramics, starting with the manufacturers of the individual raw materials, through the formulators and producers of construction products up to and including the participating industrial partners are integrated in the project. During the course of the project, the tight networking of institutional and industrial research will lead to the development of demonstrators in the shape of construction chemical products and concrete products that meet the targets.

The goal of Remmers GmbH is to establish in-depth scientific material research of binding agent systems for coating construction materials exposed to high chemical loads. The formulations should be inorganic as far as possible and have clear benefits over the currently used solutions.

The application opportunities of these kinds of coatings are diverse and include both the protection of new buildings and also the repairs of damaged buildings. Due to the huge investments required to repair the waste water infrastructure in Germany, one special area of focus of the company Remmers Baustofftechnik GmbH is to develop coating systems for the waste water sector.

BMBF-Project - FKZ: 03X0071C

The NanoLambda project is part of the ‘high-tech strategy’ of the Federal Ministry of Education and Research (BMBF) within the framework program "Materials Innovations for Industry and Society - WING" about the topic of "Nanotechnology in the construction sector - NanoTecture: Promotion of the development of higher resource/energy-saving and performance potential as well as new functions, managed by the project owner Jülich (PTJ).

Project partners: Bavarian Centre for Applied Energy Research (ZAE Bayern), Remmers GmbH, Eckart GmbH

The goal of this project is to research and develop innovative components for thermal insulation systems based on the nanostructured materials, and to make specific use of the physical effects resulting from the nanoscale structure of the materials used to improve the performance of the insulating materials and their surfaces for use in the construction sector.

Remmers was commissioned to develop low-emitting paints (‘low-e paints’) to significantly reduce the heat radiation from the surface of buildings for a joint project:

On well-insulated façades, in particular, the surface temperature can drop below the air temperature due to the heat radiation into the ambient air and also during cold nights. This leads to the creation of condensation on the surface of the façade. In the long-term, primarily on bonded thermal insulation systems, this creates algae or green discolouration on the façade, which not only impair its appearance, it is also harmful for the building substance in the long term.

This green discolouration can usually be prevented by adding biocidally-active substances into the façade coating, preferably in the lowest dose possible. When low-e paints are used, there is often no need for biocides in the façade paint:

Thanks to a low-emission surface, the heat radiated to the environment and also the surface cooling are reduced; in turn, this reduces the amount of condensation.

Alternatively, the condensation accumulation can be prevented by increasing the thickness of the plaster layer to reduce the thermal capacity of the outer layer; however, the effect achieved with this method is lower than if a suitable low-e paint is used.

To achieve this goal, metallic or semi-conductive pigments are developed that can be integrated into the paint; this means that the paint has a low emission level in the infra-red spectrum range. At the same time, however, the paint should have a colour in the visible wavelength range that is created e.g. by the colour pigments, and is not covered by the IR-active pigments. The goal is to achieve an emission level of e < 0.4 combined with the maximum retention of the colour neutrality.

Remmers spheres of responsibility in the project

Thanks to its know-how, Remmers is specifically responsible for addressing the following questions:

  • Integration of innovative substances that were provided as part of the project into proven systems to increase their sustainability.
  • Formulation of substances that were provided as part of the project into innovative systems with additional benefits.
  • Testing of the development products, if possible in-house at Remmers (otherwise by project partners and possibly by independent testing institutes).
  • Supporting function in the development of innovative raw materials with necessary properties.
  • Coordination between the project partners responsible for raw material development, recipe formulation and end use.

EU-Project – Reference no.: 260162

The research project ‘3ENCULT’ starts on the 1st October 2010 as part of the 7th research supporting program of the European Union. It is coordinated by the European Academy Bozen (EURAC).

A total of 23 partners from various European countries are working on solutions aimed at increasing the energy efficiency in historical buildings in cities. The interdisciplinary team not only looks at the climate-related aspects and the level of living and usage comfort, but in particular at issues relating to monument preservation. Therefore, in addition to the partners for the research and development, building owners and local listed building offices are also consulted.
