Research & Development

We invest judiciously and on an ongoing basis in research and development activities with the dual objective of increasing the range of products and their finishes, thus increasing the diversity of our offer and finding a sustainable and economically viable destination for the waste resulting from our exploitation, seeking its application as a product with commercial value.

Another aspect of research is related to the search for new technical solutions. This effort has already allowed us to register 2 product patents resulting from this research activity. One in the area of granite coloring and the other in the creation of a vegetal substrate originating from the residues resulting from what the company produces.

Laboratory

We have a research laboratory that allows us to respond to the demands posed by the maintenance of the quality of our products and the search for new technical solutions.

This laboratory is equipped with equipment that allows the mineralogical and physical-mechanical characterization of the raw material and evaluates the suitability of the stone products in new situations.

Thus, the evaluation of the durability of stone materials in the various situations of work, whether structural or environmental, is the most common research typology.

Innovation as the path to Competitiveness

As part of Projecto IDT nº 17376, which Transgranitos is developing in partnership with the University of Trás-os-Montes and Alto Douro, the data and technical content resulting from the research carried out in its various activities will be made available here throughout the course of the project.

Reuse of sawing waste in geopolymers

This project aims to recycle and reuse granite and marble sawing waste, transforming it into geopolymers, materials known for their high durability and strength, suitable for civil construction. Transgranitos seeks to develop a methodology to incorporate sawing sludge into the production of geopolymers, optimizing waste utilization and minimizing the environmental impact associated with the disposal of these materials. The process will include the evaluation of the physical and mechanical properties of the produced geopolymers, the investigation of potential applications in various construction contexts, and the testing of durability and strength of the developed materials.

Color enhancement in granites through flaming

It explores the chromatic modification of granites through the flaming process, a method that uses heat to alter the surface of the stone. Transgranitos aims to intensify the natural color variations of granites, potentially increasing their aesthetic and commercial value. This project will focus on the research and development of specific thermal treatments and chemical impregnation products that can enhance the stone’s response to flaming. The goal is not only to improve the visual appearance of the granite but also to ensure the durability of the colors under different environmental conditions.

Artificial soil development

This project aims to develop artificial soils using sawing slurry generated during the cutting of natural stone. The goal is to create a material suitable for the environmental and landscape restoration of areas degraded by mining and other industrial activities. The project will include the characterization of the slurry’s physical, chemical and mineralogical properties, as well as the incorporation of organic residues to improve the edaphic characteristics of the resulting artificial soil. Particular attention will be given to the soil’s capacity to support native vegetation, which is essential for the ecological recovery of affected areas.

Use of ornamental stones in thermal systems

It explores the use of ornamental stones in the transmission of thermal energy. The research will focus on the ability of stones such as granite, marble, and limestone to absorb and retain solar heat, with potential applications in water heating systems and radiant floors. This project aims to develop new technological applications that leverage the specific thermal properties of stones to improve energy efficiency in buildings and other structures. The work will include the development and testing of prototypes, thermal efficiency analysis, and studies on the economic feasibility of the proposed solutions.
