To this end, we investigate tension, compression, and shear specimens, cut from quality autoclave-cured basalt composites. Our findings indicate that, in terms of strength and stiffness, unidirectional basalt fiber composites are comparable to, or better than epoxy composites made from E-glass fibers.

Porosity is a significant physical feature of rocks due to water absorption that causes decrease in the strength. The basalt of the study area can be described as "highly porous" and ignimbrite as "extremely porous" according to the classification by Anon (1979).The average UCS of basalt is determined as 26.65 MPa.For the ignimbrite, the lowest UCS is observed in …

Basalt, sometimes known as white, green, or blue basalt, is igneous rock. This stone is good and bad for construction because it is strong and rough. This roughness makes it difficult to use the granite for any purpose. It has a specific gravity of about 3 and compressive strength of 200 to 350 N/mm2 (2039 to 3569 kg/cm2).
