Cement based conglomerate light-weighted by recycled EPS which makes the compound lighter and highly insulating. The mixture is featured by the partial replacement of sand parts/fractions with corresponding recycled EPS parts. The mixture can be used also for construction of structural components, featured by lightness, sustainability and improvement of thermal properties.

Partially prefabricated system of opaque vertical clamping, structural and not, equipped with thermal insulation and armature. The system is constituted by a disposable formwork provided by means of two panels in the conglomerate to which are made integral two additional panels to high thermal performance in EPS, with contoured surface structure. The panels are connected together by horizontal transverse connections, to form a cavity containing an armature arranged in the establishment, adapted to accommodate a concrete casting (or equivalent) in work that may also provide for the use of innovative materials. The so-configured panels, they become an integral part of the vertical clamping system; the jet of completion, to be carried out in situ, connects between their walls arranged in both longitudinal and transverse direction, helping to create a single integrated structure. The system is designed to be able to withstand suitably the vertical and horizontal stresses of seismic type and to be be equipped.
