Basalt Properties, Composition and Formation | Earth Know
Basalt description and properties. Basalt is a massive, dense, hard, dark-colored rock with a density of about 2.9g/cm 3 and a Mohs hardness scale of 6-7. It is often dark gray to black on a fresh surface since dark-colored mafic minerals. However, it can have brown-black or greenish-black hues dominate it. Also, rare kinds can have lighter ...

Mechanical properties of basalt macro fibre reinforced …
As compared to traditional basalt fibres, basalt macro fibres (BMFs) have much higher durability in alkaline environments [8]. BMFs are a type of novel fibres that consist of bundled basalt fibres embedded into a resin matrix, forming mini basalt fibre-reinforced polymer (BFRP) bars with a diameter of approximately 0.7–1.0 mm [9].

(1) Basalt fibers had a significant effect on the fracture behavior of the FAGC samples. The descending segment of the load-CMOD curves of basalt fiber–reinforced FAGC dropped more slowly than that of plain FAGC. Basalt fibers promoted the elastic modulus of FAGC, whereas basalt fiber–reinforced FAGC manifested the maximum peak load of 1480 N.
