The present invention relates to a cementitious composition adapted to form mortars or cements comprising glass as an additive having reduced tendency to reaction with alkali, characterized in that said glass is obtained by grinding and subsequent washing with water.

Activated pulverised glass as an additive for mortars and cement, and related cementitious products

The present invention relates to a method for manufacturing prism-shaped panels (), each comprising through portions () made of translucent material adapted to transmit light between two opposite sides of the panel. The method includes arranging a plurality of elements () made of translucent material in a formwork so that the main direction of development () of such elements is parallel to the vertical direction of development () of the formwork. The method includes pouring cementitious mortar into said formwork () so that said cementitious mortar is distributed between said elements and so as to generate, after the hardening of said cementitious mortar, a substantially prism-shaped semi-finished cementitious mortar product () in which said elements made of translucent material are incorporated. The method further includes extracting the semi-finished product from said formwork after the hardening of the cementitious mortar, and cutting the semi-finished product according to cutting planes orthogonal to the longitudinal direction () in which the elements incorporated in said semi-finished product develop, so as to obtain prism-shaped parts, each of which corresponds to one of said panels ().

Solid mixture for the preparation of concrete which after 16 hours has a mechanical resistance higher or equal to 50 MPa comprising cement and limestone aggregates, substantially lacking latent hydraulic activity, characterized by the presentation of a specific granulometric distribution curve.

High performance concrete with a quick resistance development lacking added materials with latent hydraulic activity

The present invention concerns a composite cement paving with photocatalytic action for reducing urban polluting agents, composed of a bituminous or cement foundation, a resin having the function of interface, a superficial cement layer with photocatalytic properties able to reduce organic and inorganic polluting agents, said paving also comprising reinforcing materials and possible suitably positioned fibrous materials. The paving thus realised presents a strong photocatalytic action, prolonged overtime, even in the presence of high mechanical stress caused by heavy traffic.

High durability photocatalytic paving for reducing urban polluting agents

A solid mixture for the preparation of concretes with a mechanical strength after 28 days that is greater than or equal to 110 MPa comprising cement, calcareous aggregates and admixtures characterised by the fact that any additions with latent hydraulic activity are less than 5% by weight compared to the cement.

Performance concretes that do not contain additions with latent hydraulic activity

Limestone filled Portland cement wherein the fineness of limestone particles ranges from 5,000 to 12,000 Blaine and the fineness of clinker particles ranges from 1,500 to 3,000 Blaine.
