Construction Materials

The company was born as a laboratory for testing construction materials. Technicians and professionals of this department stand out because of their innovative spirit, which enables that the company has been always a reference in the development of new testing procedures and regulations in the construction sector. The Construction materials Area of the R&D Division rose up as a guide for this innovative spirit and a framework for the innovations in this area within research projects. CEMOSA’s activities within those projects can be grouped as follows:

  • Laboratory testing: CEMOSA is able to carry out almost every type of testing according to EN standards in soils, concrete, asphalt mixtures (cold and warm), ceramics, etc., but it also develops own equipment and testing procedures when there is a new material that cannot be characterised using typical procedures. Examples of these exclusive testing equipment are a test bench for structural elements up to 5m length, UV and IR chambers for accelerated aging tests, permeameters and large test boxes for real scale tests.
  • In-situ testing: In the field of geotechnics, the ownership of borehole machines and auscultation systems allows to carry out any survey project with the highest flexibility and reliability. In the field of structures, the main in-situ testing are load testing and welding control. On the other hand, CEMOSA has a patented equipment for the assessment of voids percentage and permeability on a large scale in porous surfaces, such as porous asphalt road pavements.
  • Study of new materials: CEMOSA’s laboratory has the technical resources required to make samples of the main construction materials (concrete, asphalt mixtures -cold and warm-, etc.) and capabilities to study new  typology of materials. The physical-mechanic and chemical characteristics of these new materials enables their use in numerical models and finally the validation and correlation of their parameters, closing the reengineering loop.
  • Quality certification: Construction materials as well as laboratory testing needs to be subjected to normalisation and standardisation before their introduction in construction works. In the initial research phase, it is required to draft the specifications that allows their rapid implementation by the proper public bodies. CEMOSA, as certified laboratory and notified body for CE marking, have the required experience to draft these documents whether for cold mix asphalt or concrete and soils.

The R&D department does not carry out research tasks related to the manufacturing of new construction materials, or is involved with the improvement of the properties of existing ones that can be subject to evaluation by the Notified Body CEMOSA.
