Aggregate - Basalt
It is a dark rock with a characteristic porphyry or glassy structure, sometimes with growths of individual minerals. Basalt has a characteristic fine-grained structure formed by the rapid solidification of lava on the surface of the planet. It has columnar cleavage and less than 20 volume percent quartz, less than 10% foids and at least 65% feldspars in the form of plagioclase. The product is intended as a backfill or drainage mixture and a material for landscaping or strengthening surfaces.
