Designed for sustainable construction

Master Builders Solutions® experts from BASF have presented a broad portfolio of construction solutions at Barcelona Building Construmat, as well as case studies illustrating the advantages and sustainability of these.
Innovative concrete mixture
Based on an innovative molecule structure, the new MasterSuna enables sands containing swelling clay to be used in the production of high-quality concrete. This in turn enables concrete producers to significantly reduce their costs. Given their availability, sands contaminated with swelling clay from local sources can be used, thereby reducing, or omitting the need to secure additional suitable sands from remote sources.

Owners of sand quarries can also benefit from the use of MasterSuna SBS. Historically, sands contaminated with swelling clay could only be utilised in less-demanding applications, if at all. However, MasterSuna SBS now makes it possible to use existing deposits to a much greater extent.

Furthermore, the washing and pre-treatment of local sands can also be reduced, thus increasing the economic value of the sand quarry. At the same time, the number of new sand quarries to be developed can be reduced as well.

Corrosion inhibitor
The silane-based corrosion inhibitor, MasterProtect 8000 CI, protects reinforced concrete structures in two ways, firstly by the corrosion inhibition, which strengthens the passive layer on the steel, and secondly by reducing the ingress of water by creating a hydrophobic barrier in the concrete matrix. This unique combination makes the product ideal for service life extension after repair.

Elastic waterproofing
The MasterSeal 6100 FX waterproofing slurry combines powerful binding systems and powdery polymers. Designed and developed in alignment with LEED (Leadership in Energy and Environmental Design) criteria for ecologically high-performing buildings, MasterSeal 6100 FX scores extremely well due to the use of recycled content, regional material, and low-emitting materials.

Sustainability in practice
Master Builders Solutions also revealed how its product portfolio improves eco-efficiency. For example, resources can be used more efficiently, thereby significantly reducing costs, as documented by assessment methods such as BASF’s Eco-Efficiency Analysis or the Life-Cycle Analyzer.

Providing many relevant examples, the Europe-wide Master Builders Solutions sustainability campaign, launched in 2017, showcases projects where customers were able to increase their productivity while at the same time reduce costs and emissions thanks to the advanced chemistry from BASF.

In one such example, the precast manufacturer Uniblok – a Velatia company in Toledo, Spain – achieves extraordinary results with their concrete by mixing in MasterFiber. The advanced fibre technology from Master Builders Solutions strengthens concrete and reduces the amount of steel reinforcement required. With MasterFiber Uniblok could increase their efficiency by 10% and reduce their global warming potential by 21%.
