Cross segment of a concrete railway sleeper underneath a rail Construction aggregates consist of massive chunks of material in a very concrete mix, normally a coarse gravel or crushed rocks which include limestone, or granite, alongside with finer materials for example sand.
Lessening the cement clinker written content may have constructive results around the environmental existence-cycle evaluation of concrete.
