Aggregates Laboratory
Aggregates are used in producing concrete and mortars, roadway layers (subbase, base, and wearing course), and railway bed (ballast). They are also used in rockfill and drainage.
Our technicians and engineers assist aggregate producers with all issues related to their operations. Whatever the mission, whether it involves product quality control, deposit reconnaissance, or advising on adjusting aggregate production facilities, we have the knowledge and resources to successfully carry out all tests, analyses, and studies.
Our missions include:
Sampling
Our teams collect material samples for physicochemical analyses or laboratory studies. To this end, we conduct manual, Auger, and shovel drilling, as well as destructive drilling and coring.
Analysis and Control
Standardized laboratory testing methods allow us to characterize different categories of aggregates to verify their suitability for their intended use, in accordance with product standards and industry standards & best practices. All the tests we offer are presented in our catalog as follows:
