We are preparing the future of low-carbon construction every day
The applications of Ecocem GGBS are not limited to concretes; there are many different options, and there is great potential for the development of this technology. Research and Innovation are therefore at the core of Ecocem’s activity. The applications currently available on the European market or in development include: Geotechnical binders for soil treatment and special foundations, quarry filling, deep foundations, grouting, moulded walls, waterproof screens and jet grouting.
Ecocem BBGS is now widely used for its technical advantages in non-structural precast elements (pavers, concrete blocks, curbs) and structural elements. In addition, Ecocem has developed Ecocem R +, which is intended for unreinforced precast products and has been adapted to the industrial process. Soon, Ecocem will launch Precast binders, which have a very low carbon footprint. These binders contain at least 90% Ecocem GGBS and 10% chemical activators. The carbon footprint of these binders will therefore be 100 to 150 kg/tonne, about six times lower than current market offerings. They can be used for manufacturing blocks, pavers or curbs in compliance with government initiatives for new low-carbon constructions.
Mortars made from Ecocem GGBS meet this market’s growing demand for high-performance, low-carbon products. The consistent performance of our GGBS offers manufacturers a guarantee of stability for their products. Ecocem offers formulations using a high level of GGBS for major industrial mortars, which can in turn be used to formulate a large range of mortars offering benefits for different applications:
- – Tile adhesives
- – Coatings
- – Mortars for outdoor thermal insulation systems
- – Floor coatings
- – Masonry mortars
- – Concrete repair mortars
Ecocem GGBS formulations offer better health and safety conditions for producers and applicators: Ecocem GGBS formulated mortars are non-irritating, and do not include Chromium VI. Ecocem is aiming to soon develop, alongside its partners, “pure GGBS” mortars so that resulting products possess optimal characteristics.
Fluid screed solutions
Ecocem GGBS shows great potential for pouring fluid screeds. Indeed, its technical advantages reduce pouring difficulty, and ensure much higher productivity at construction sites thanks to its fluidity. The newly Ecocem formulated product developed by the group’s research is ideal for this application:
- – Its drying time is fast regardless of temperature (between 5 and 35°C) or humidity;
- – Its dimensional stability is excellent, eliminating tiling and cracking;
- – Its resistance to water is comparable to a cement screed;
- – Its fluidity and drying ensure a flat and even finish for contiguous surfaces of up to 500m² and larger.
This application is currently being launched in the Netherlands by Ecocem Benelux for a number of different projects including industrial buildings as well as individual and collective housing.
Soil and sediment stabilization
Europe has adopted an Integrated Pollution Prevention and Control (IPPC) directive, legislation against PCBs, and the Environmental Quality Standards Directive (EQSD), while it has forbidden Tributyltin (TBT, biocide). In spite of this legislation, chemical levels remain a serious matter of concern in European waters, especially with regard to persistent pollutants in harbour and river sediments, which remain long after emission reduction measures have been taken. Faced with this environmental problem, some European countries have decided to treat polluted sediments in order to store them without environmental risks, or to re-use them, particularly as road or construction materials.
In this context, Ecocem has developed GGBS-based binders which meet specifications for the massive leaching of pollutants such as heavy metals or TBT. These binders guarantee the long-term mechanical strength of the sediments, which grow stronger over time and ensure the stability of the treated materials.
Many other projects are currently being tested. In parallel with research carried out in Ecocem labs, we are supporting research carried out in partnership with engineering schools.
