Construction
Our Hansa products are used to maintain the workability and flow of concrete and gypsum, while increasing the strength.
Similarly, these plasticising and binding properties of CollexForte are applied in the manufacture of ceramic tiles and bricks.
What are Hansa and CollexForte?
Hansa is an environmentally friendly lignin-based biopolymer which is designed for the ready-mix concrete market, where it is used in admixtures for improved cement particle dispersion, enhanced flow characteristics and workability. Given its dispersive and plasticising properties, it is equally suitable for application in the manufacture of gypsum board products.
CollexForte is used for application in the production of ceramic tiles and bricks, where the same performance characteristics are required.
Product benefits
Environmentally friendly alternative for synthetic products.
Water savings - The wetting action of Hansa ensures that the water content of the concrete or gypsum can be reduced without compromising the homogeneity of the cementitious mixture.
Prolonged fluidity - The duration of fluidity and workability of fresh concrete or gypsum can be prolonged.
Increased strength - The use of Hansa with a reduced “water-to-aggregate” ratio significantly increases the strength of the hardened aggregate.
Energy savings – Due to less water being required, less energy for processing, drying and firing is needed.
