Composite panel based on cementitious mortar with properties of transparency

摘要

The present invention relates to a composite panel (10) based on cementitious mortar, passed through its entire thickness by a plurality of through openings (11), each of which is filled with a material transparent to light in the form of a preformed plate (12) housed in said opening (11), or formed in said opening, wherein said cement-based mortar contains at least 30 kg/m 3 of fibers selected from one or more of the following types: metallic fibers, steel fibers, glass fibers, polymeric resin fibers. The invention also relates to methods of production of said panel.

1. A composite panel based on cementitious mortar, with properties of transparency to light, passed through its entire thickness by a plurality of through openings each of which is filled with a material transparent to light in the form of a preformed plate housed in said opening, or formed in said opening, wherein said mortar based on cement contains at least 30 kg/m3 of a mixture of two types of fibres, a first one selected from the group consisting of metallic fibres and steel fibres, mixed with a second one made of polymeric resin fibers, in a ratio by weight between 40-50 to 1 respectively, such mixture of fibers controlling the hygrometric shrinkage of the mortar and opposing cracking.
