It is the second most consumed raw material by humans after water.
This natural aggregate is characterized by its chemical composition, physical stability and granulometric size. The use of this raw material is essential to the socio-economic development and infrastructure of a country, and is reflected in the quality of life.
These are inert solid materials of assorted sizes, used in formulations with other binders in the production of concrete, asphalts and mortars. They are also directly used in fillers, road surfaces and railway ballast.
Calcinor has units dedicated to aggregate washing as well as grinding and for particle classification, minimizing the presence of impurities that exist in the raw material, ensuring a constant and homogeneous composition.
All of this gives rise to a wide range of products, from unbound aggregates for fillers to minerals classified for more specific applications – including colour variations - the most important being the white aggregate from Cales de la Plana. This range also includes concretes with different technical characteristics, resistances and typologies of the matrials used in their production, as well as mortars and asphalts.
As an example of Calcinor´s commitment to the environment and the conservation of natural resources, we can incorporate into formulations:
