Concrete aggregates

This product is an strategic input for the concrete and cement industry. In Chile the production for aggregates is controlled by National regulations and codes, demanding for instance that aggregates must be washed, because of which the process generates wastewaters.

Aggregates for concrete must comply the requierments of the Chilean Code NCh 163Of79 "Ággregates for mortars and concrete - General Requirements", while is on revision the new code NCh 163-cR2012.

The main products offered by Soc. Construcciones y Servicios Najar Ltd. to our clients are gravels 1 1/2" and 3/4" and sand.
