Basalt Fibers Reinforced Concrete: Strength and Failure Modes
The low tensile capacity of concrete often results in brittle failure without any warning. One way to cope with this issue is to add fibers and essentially improve the tensile strength (TS) behavior of concrete and offset its undesirable brittle failure. In recent investigations, basalt fibers (BFs), as compared to a variety of other kinds of fiber, have …

Basalt
Basalt is a fine-grained and dark-colored rock. Black color is given to basalt by pyroxene group mineral augite. Width of the sample is 12 cm. Basalt is usually black or dark gray and relatively featureless. It is composed of mineral grains which are mostly indistinguishable to the naked eye. Basalt may also contain volcanic glass.

8. STRENGTH OF SOILS AND ROCKS
Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement. The results of a number of direct shear tests are shown in Fig. 8.9. The sand yields a shear stress-normal stress plot similar to that of the sliding block in Fig. 8.7 but the clay gives an
