Cast basalt sand is durable, heat-resistant, and chemically inert—perfect for cast basalt mortar, abrasive media, and high-performance concrete applications.

Basalt is a type of volcanic rock formed by the cooling and solidification of molten lava that come out of the cracks of the earth's crust. Basalts are generally dark black in color. Basalt is a hard and hard stone and it is used in ballast, gravel and sandblasting industry. It is used in basalt sandblasting industry that does not contain free silica. Basalt is a rock with a hardness of 6.5 mohs and a density of 2.77 gr / cm3, which contains 45-50% SiO2. Basalt sand is used in scraper in the range of 0.5-1.6mm, 1.0-2.0mm and 1.5-2.7mm.

“It’s stone, but not as we know it!”

High-density, abrasion-resistant granules for industrial applications.

Cast basalt aggregate is made by melting volcanic rock at high temperature, casting it into solid forms, then crushing into graded granules. It retains excellent mechanical strength, chemical inertness, and thermal resistance.
