system for making prefabricated structure, however complex, total weight, extremely reduced in concrete, thickness small, armed with nets.

摘要

A concrete structure of low weight and thickness, and possessing high characteristics of impermeability, low cracking excellent shape stability and good mechanical resistance, for manufacturing articles having a main surface of a predetermined shape; in which the structure consists of a layer of concrete 11 with a high cement content comprising aggregate 11a and at least one anticracking reinforcement 12, in which the anti-cracking reinforcement consists of a reticular structure of wires 13, 14 having fine sized meshes D with a function of the maximum dimension R of the aggregate according to the formula: D is equal to or greater than k times R, where k is a coefficient higher than 1.2.
