Properties of Heavy Concrete Made with Barite Aggregates

Barite aggregate behaves in concrete similarly to an ordinary crushed aggregate such as limestone or basalt, and no special problems were encountered in selecting and proportioning the constituents of the concretes. Exceptionally high compressive strengths were developed by conventional barite concrete.
