Ciment et Architecture

Glossary

Sand

Granulate graded under 5 mm, resulting from the disintegration of mineral rock or from its mechanical crushing. In terms of weight it is the major constituent of mortars and concretes.

Setting accelerator

Additive for concrete or mortars that is put in the mixing mortar to reduce setting time by accelerating hydration of the cement.
In cement works, grinding workshops generally comprise a grinding machine, a separator –which allows the bigger pieces to be returned to the grinder – and a de-dusting and ventilation assembly.
