Construction aggregates are mineral materials used in the production of construction materials such as Portland cement concrete and hotmix asphalt, and as unbound base courses for pavements. In their primary role as filler in these materials, the volume of aggregates can take up 90 – 95% of asphalt and 70 – 80% of concrete mixtures.

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categoriesfine and coarse.

The processed aggregates can be combined with cementitious materials in the manufacturing of concrete or bitumen as a binder in the production of asphalt. Aggregates solutions available at LafargeHolcim can be divided into two main categories: Primary natural aggregates, extracted from hard rock quarries and deposits of sand and gravel.
Concrete and aggregates were made for each other — aggregates are the most mined resource in the world and concrete is the most frequently used manmade material!
