For both basalt samples, rock crushing in a cone crusher system resulted in a higher content of non-cubical and flaky grains (especially for classes above 16 mm) in the product after crushing, relative to crushing in a jaw crusher system, regardless of the geometric composition of the feed grains.
When, however, the crushing-strength was compared with the wet attrition and water-absorption (Fig. 44, Plate 1), excluding the rocks with a dominant content of olivine, namely, Nos. 50,52 and 53, there was a direct relation between the absorption value and the crushing-strength, thereby indicating that the porosity produced by decomposition ...
Basalt crushed stone is a granular material produced by crushing basalt rocks. It possesses a black or dark grey colour and a sturdy structure, resulting from the high concentration of minerals like pyroxene, olivine, plagioclase, and others. Characteristics of basalt crushed stone and wedges: – High strength and tear resistance;
Methods. Samples of basalt, volcanic ash, basalt + cement and cement dust were collected on the construction site of a subway tunnel, ground to dust and subjected to the Microtox ® solid-phase test to evaluate the toxicity of dust suspensions. Samples were investigated by scanning electron microscopy equipped with energy dispersive X-ray analysis (EDX).
