Technology for using mineral wastes as raw materials for additive manufacturing of cement and concrete

Short summary A Spanish Technological Center leader in the development and implementation of new technologies for the non-energy mining sector is looking for EU organizations with expertise in the application of imaging spectroscopy techniques for the location and evaluation of abandoned mine sites in order to map mineral potential for recycling purposes for mapping the spatial distribution of mineral compositions in order to reach a research cooperation agreement.

Full description The Technological Center is looking for organizations with expertise in the application of imaging spectroscopy techniques for the location and evaluation of abandoned mine sites in order to map mineral potential for recycling purposes using, the potential of imaging spectrometry as an environmentally sustainable technology for mapping the spatial distribution of mineral compositions including metallic minerals, construction minerals and industrial minerals. The main objective of this technical collaboration is to reach a collaboration agreement for the development of a new circular economy technology for the aggregates and natural stone wastes as raw materials for additive manufacturing of cement and concrete. The development will undergo: 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 will be studied and tests on fresh material and 3D printing tests will be carried out. Final applications of the sludges waste for additive manufacturing of building elements will be developed through: a) tests on hardened material, b) tests on 3D printed material and c) characterization and applications. The 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. The Center has a rich database, a strong infrastructure, and competent human resources as well as a broad experience participating in EU financed programmers.

Technical Specification or Expertise Sought Scientific-technical organizations (companies, Universities, start-ups, Technological Centers) with expertise in the industrial applications of additive manufacturing.
