AGGREGATES FOR CONCRETE AND PROCESS FOR THEIR PREPARATION

摘要

The present invention relates in general terms to a recycled aggregate and a process for preparation thereof. Said process, in particular, is characterized by a controlled mixing stage of a waste material with cement, in a presence of at least one silicate, followed by curing and crushing steps. The composition of the invention, in the form for example of pseudo-spherical aggregates, is useful in particular as an inert component for the formulation of concretes and the like and further makes possible the recovery of waste material.
