The tensile strength of basalt is very high, much greater than carbon fiber or fiberglass. Therefore, melted composites of the rock are used for manufacturing pipes and rebars that are used in the construction of wind turbine blades. Ophitic basalt is often used in the medical industry for orthopedic purposes.

a compressive strength of 6,700 psi. It appears that the strength of a well- graded sulfur-aggregate concrete would then depend on the strength of the aggregate as suggested by the one mixture with basalt. Essentially no work had been done using basalt, one of the rocks that appear to be indigenous to the lunar surface. Some forms of basalt yield a
