This information is based on our present state of knowledge.It is intended for public introduction of our products and their uses. This description should not be construed as a guarantee of the products specific properties or serviceability for a particular application.
Cellulose used in construction can be used to increase the strength and durability of concrete, reduce its shrinkage and cracking, increase its elasticity and toughness, and improve its frost resistance and chemical corrosion resistance. It can also be used to strengthen walls, roofs, and floors, improving the overall load-bearing capacity and seismic resistance of buildings.
