Abstract
This invention relates to a composite panel made from wood and cementitious binders, with flat surfaces and several possible colours. The said panel comprises 35 to 85% of grey or white Portland cement; 10 to 30% of debarked resinous wood particles; 5 to 20% of semi-hydrated calcium sulphate; 0 to 10% of a surface accelerator; 0 to 10% of aluminium sulphate solution; 0 to 30% of calcium carbonate; and 0 to 15% of pigments. The invention uses the process of preparation for the existing VIROC panel, adjusting it to the new material. This panel, in addition to being very resistant and showing high performances in terms of resistance to impact, humidity, temperature variation, noise and fungi, as well as other microorganisms, also complies with all the requirements of the associated product standard.
