When the basalt fiber content is 0.26 %, the fractal dimension of BFRC is the smallest. This shows that the addition of appropriate basalt fiber content can effectively reduce the damage degree of concrete. The particle size distribution of BFRC after crushing is shown in Table 4.

The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to …

basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium. Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact. It is more usual, however, for them to exhibit porphyritic structure, with larger crystals (phenocrysts) of olivine, augite ...
