Basalt is the most widely distributed basic extrusive rock, with a sio 2 content ranging from 45% to 52%, and is mainly composed of basic plagioclase and monoclase pyroxene, followed by orthopyroxene, peridot and amphibole. pyroxene in basalt often has a complete crystalline, short columnar structure; plagioclase in basalt has a fine needle-like nondirectional arrangement.
The aggregate sample consists of a mkture of 3 fractions; 50 weight% 8/10 mm, 25 weight% 10/11.2 mm and 25 weight% 11.2/12 mm. about 1 to 1.5 kg of this mixture is placed in a mould on which a stamp exerts a load of 1 k n . the sample is subjected to 10 blows of a 50 kg hammer, falling freely from a height of 370 mm.
