Aggregates are rock fragments extracted from fluvial deposits as in the case of natural sand and gravel or quarried from hard rock formations.?The extracted materials are then processed by crushing, shaping, and screening, including washing where required, into final products.?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.
- Alternative aggregates, consisting of recycled concrete and secondary aggregates from other industrial waste, such as mining waste, slag, and ash.
Whatever the application, LafargeHolcim ensures all aggregates products are of the best quality in terms of particle shape, durability, and resistance to weathering. As a result, our customers can rely on the performance of LafargeHolcim aggregates.
