The finished NORDECA plate consists of: 60% wood wool, 39% portland cement, about 1% mineralizer. This proportion is the golden mean for a wood-cement plate, when all the positive properties of wood are preserved and at the same time they are protected by the properties of cement. Wood wool is a ribbon-like fiber 1-3 mm wide and up to 25 cm long, made of wood on specialized equipment. The plates have valuable qualities of wood, as a natural environmentally friendly material, its strength and excellent thermal insulation. The second main component for the manufacture of slabs is Portland 500 grade. The cement content provides finished slabs with durability and durability. For the mineralization of wood wool used liquid glass solution - office glue. When processing, the thinnest film is formed on the surface of wood wool, which prevents the interaction of wood sugars and cement, while reducing the "setting" of cement and improving the "grip" of wood and cement.
