Basalt is among the most used rocks as aggregate, ballast, ornamental stone and for other construction purposes. Therefore, the uniaxial compressive strength (UCS) and elasticity modulus (Ei) of intact rock are required to be known for several purposes. For this reason, the purpose of the present study is to develop various non …

The effect of BF length on elasticity modulus, as studied by Mehran et al. (Khan et al., 2022), is summarized in Fig. 11. The results of the tests revealed that adding basalt fibers reduced the modulus for all fiber lengths. Furthermore, an increase in the fibers length, led to a greater reduction in elastic modulus (up to about 20%).

Basalt. Igneous rock, with a fine texture and grain size < 1 mm (extrusive). It is a basic rock, with a total silica content of 45-55%. Predominant minerals in this generally dark colored rock are hornblende and plagioclase feldspar. Property values are typical of Basalt used in construction. Actual property values will vary from sample to sample.
