The Materials Analysis Laboratory (MAL) is an analytical laboratory for, the quality control of mineral raw materials, non-metallic inorganic materials and other industrial materials.


The diversity of the performed tests is one of the main differentiating factors of MAL, covering a wide range from the Characterization of materials to the Environmental and Industrial Hygiene Controls.


Within the accreditation scope of the laboratory are 62 accredited tests which cover the following technical areas:

  • Aggregates and Inerts
  • Asbestos
  • Ambient Air
  • Concrete, cement and mortars
  • Gaseous effluents
  • Liquid effluents
  • Solid waste
  • Ceramics and glass


The laboratory guarantees solid technical competence, based on specialized and experienced human resources and offering a wide range of equipment. Our team is qualified for controlling the quality of several matrices, according to analysis methodologies described in national or international standards, or even through internally developed methodologies, duly validated.


Regarding Quality Control, MAL’s goal is the reliability of obtained results and actions of Internal and External Quality Control are developed, using the regular use of Certified Reference Materials and the continuous participation in various programs of international interlaboratory tests.
