Basalt is the most common rock on Earth's surface. Specimens are black in color and weather to dark green or brown.

They can also be porphyritic, with phenocrysts of olivine, augite, or ...

Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro.

Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near-surface environment of Venus.

Basalt composite rebar consists of a polymer matrix and reinforcing elements. Thousands of continuous basalt fibers of high strength, combined with each other into a core by a polymer matrix, act as reinforcing elements. Outside, the rod is pulled together by a winding basalt twisted thread, which gives the surface a constant continuous ribbing.

The results demonstrate that, given a basalt fibre (BF) dosage of 0–7.5 kg/m 3, 18 mm BF can significantly increase the residual stress under the same deformation, rather than the peak values of the flexural strength. Meanwhile, the trend in the flexural toughness increases to a peak at a dosage of 3–4.5 kg/m 3, followed by a declining curve.
