ABSTRACT. Basalt fiber as a type of reinforced material has been widely used in fiber-reinforced polymer (FRP) composites. Iron oxide (Fe 2 O 3) has a great influence on the thermal and elastic properties of basalt fiber.In this study, ultrabasic, basic, and intermediate basalt rocks were chosen as raw materials and the dependence …

To study the frictional properties of bare rock surfaces, experiments were designed in unconfined single-direct shear configuration, in which two blocks were juxtaposed to simulate a fault surface (Fig. 1 c).In this experimental geometry, the sliding area of 16 cm 2 was also kept constant during the test. Due to limited tensile strength of …

A basalt fiber dosage of 0.2% has little effect on the flexural strength of the modified mortar. (c) The highest flexural strength of the modified mortar is observed with a clay-to-lime ratio of 3:1 and a basalt fiber dosage of 0.3%. (d, e) A basalt fiber dosage larger than 0.6% makes no contribution to the flexural strength of the modified mortar.

Basalt is defined by its mineral content and texture, and physical descriptions without mineralogical context may be unreliable in some circumstances. Basalt is usually grey to black in colour, but rapidly weathers to brown or rust-red due to oxidation of its mafic (iron-rich) minerals into hematite and other iron oxides and hydroxides.
