About

Our organization have developed a new circular economy technology for the aggregates and natural stone wastes as raw materials for additive manufacturing of cement and concrete. The development undergoes:

  1. Preliminary studies and scheduling of trials;
  2. Granulometric adaptation and sample preparation;
  3. Dosage tests and fresh characterization;
  4. Extrusion and applicability tests.

The workability and setting of 10-liter kneading have been studied and tests on fresh material and 3D printing tests have been carried out. Final applications of the sludges waste for additive manufacturing of building elements have been developed through:

a) tests on hardened material, b) tests on 3D printed material and c) characterization and applications.

Our area of expertise covers use of marble wastes for different applications, such as the ceramic industry or as amendments for the rehabilitation of soils contaminated by heavy metals. We have a rich database, a strong infrastructure and competent human resources as well as a broad experience participating in EU financed programmes.
