The present invention relates to lightweight mortars, consisting of 20 to 55% of limestone or siliceous aggregate; 30 to 70% of hydraulic binders; 5 to 15% of cork granulate; 0.5 to 10% of calcium hydroxide or magnesium hydroxide; 0.05 to 1.0% of a cellulose derivative; 1 to 5% of re-dispersible powder; 0.01 to 2% of a hydrophobic powder; 0.005 to 0.5% of an air introducing agent; and 0 to 0.5% of an air introducing agent and a retraction control agent. The invention also relates to the process for the preparation of such mortars using an aggregate with natural and renewable origin. These mortars are lightweight and, in addition to properties of thermal and acoustic insulation, they have excellent durability, excellent performance facing fire with absence of flame and toxic gases release.

The present invention relates to the field of construction, involving knowledge of building materials and sensors technology. The invention consists of a cementitious material structure with sensors, which includes a plurality of sensing elements (1) integrated on at least one substrate (2), and wherein the set of the plurality of sensing elements (1) and the at least one substrate (2) is involved in cementitious material. The invention thus enables a wide variety of ways to interact with construction structures, while allowing durability and robustness of these structures and their sensing elements (1). The present invention also comprises a manufacturing method of a cementitious material structure with sensors, which includes the integration of sensing elements (1) on at least one substrate (2), its insertion into a formwork and filling with cementitious material.

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.
