Can crushed basalt be used in concrete?

From the perspective of basalt's physical properties, it is a hard rock with excellent compressive strength. However, improper selection of crushing equipment can cause severe wear on machinery. Therefore, choosing the right equipment is crucial when crushing basalt. Can crushed basalt be used in concrete? Here's the answer:

Basalt is a basic volcanic rock and sedimentary rock. Among sand and gravel aggregates, basalt features high hardness, heat resistance, strong compressive strength, and corrosion resistance. These properties make it a primary aggregate for constructing highways, railways, airport runways, and other infrastructure. It also serves as an excellent lightweight aggregate for high-rise building concrete, commanding significant economic value in the market.

Concrete imposes multiple specifications on aggregate, including clay content, compressive strength, particle shape, and particle size. While compressive strength and hardness are not concerns for basalt, clay content, particle shape, and size are controllable factors. This means that with a well-designed production plan and appropriately configured equipment, crushed basalt aggregate is fully suitable for concrete production.
