Abstract: The present invention relates to a white or colored cementitious mixture for the manufacture of micro-concrete or normal concrete, mortar or pastes with thermochromatic properties, i.e., changing its color depending on the temperature at which the material is exposed. This color change is reversible after some time of exposure to another level of temperature. This cementitious mixture comprises the following components, in percentage in weight of the components relative to the total weight of the composition: a) 35-80% of white or gray Portland cement; b) 0.1-30% of finely ground limestone filler; c) 0.01-3% of powdered super-plasticizer; d) 0.01-3% of modified polyvinyl resins; e) 0.01-5% of dispersant of vinyl acetate and ethylene copolymers; f) 0.3-15% of encapsulated photochromic copolymers; and also one or more components selected from: g) 1-10% of binding regulator; h) 0.1-4% of zinc stearate; i) 1-20% of metakaolins; j) 5-60% of artificial pozzolans; k) 0.1-15% of inorganic pigments.

Abstract: The present invention relates to a cementitious coating with hydrochromatic properties for micro-concrete or normal concrete, mortar, or other construction materials based on cement and ceramics. This cementitious coating in acrylic solution changes its opacity depending on the presence of water and moisture. This color change is reversible after some drying time leaving invisible the markings already existing on the substrate. This cementitious coating comprises the following components, in percentage in weight of the components relative to the total weight of the composition: a) 0.5-30% of hydrochromatic acrylic copolymer emulsion; b) 5-30% of white or gray Portland cement; c) 0.1-30% of finely ground limestone filler; d) 0.01-2% of powdered super-plasticizer; e) 0.01-3% of modified polyvinyl resins; f) 0.01-5% of dispersant of vinyl acetate and ethylene copolymers; g) 15-70% of aqueous acrylic emulsion; and optionally h) 0.1-15% of inorganic pigments.

Abstract: A white or colored cementitious mixture for the manufacture of micro-concrete or normal concrete, mortar or interactive pastes with photoluminescent properties, which respond to an incident luminous stimulus when exposed in a dark environment, decaying after several minutes. The cementitious mixture comprises the following components, in percentage in weight of the components relative to the total weight of the composition: a) 35-80% of white or gray Portland cement; b) 0.1-30% of finely ground limestone filler; c) 0.01-3% of powdered super-plasticizer; d) 0.01-3% of modified polyvinyl resins; e) 0.01-5% of dispersant of vinyl acetate and ethylene copolymers; f) 0.3-20% of photoluminescent pigment based on strontium aluminate, or other, of various colors; and also one or more components selected from: g) 1-10% of binding regulator; h) 0.1-4% of zinc stearate; i) 1-20% of metakaolins; j) 5-60% of artificial pozzolans; k) 0.1-15% of inorganic pigments.

Abstract: A method for application of optical fibres in cold moldable materials, produced using binders such as plaster. First, the optical fibres are mounted to distribute the fibre according to a preset network mesh aimed at obtaining the desired pixelization effect in specific targeted areas by affixing the terminals of the optical fibres to a plasticized film that coats the formwork's surface. The concreting of the piece is carried out after the required operations of framework assembly and pre-stress, if applicable, eventual installation of “Tremi” tubes for the concrete to be discharged during concreting, insertion of spacers and accessories required for concreting of the piece. The formwork is removed after the hardening period and the terminals of the beams connected to an electronic light system; the terminals are arranged in order to obtain the desired light transmission to each one of the cables forming one pixelized unit.
