Engineering Geological Characteristics of Quartzite Types ...
The rock is hand crushed apparently because the miners lack the resources for mechanical crushing apart from the fact that mechanical crushing may completely pulverize the rock into sand due to its inherent weak strength.

2006-3-19 In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Furthermore, if a rock mass is cut by directional joint sets , the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under consideration.

2009-2-23 compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.

2015-7-4 In addition, crushing strength is also related to porosity, grain size and amount of altered minerals in a rock. A high crushing value indicates a weak, potentially non-durable material (McNally 1998). Thus, the lower the ACV, the stronger the aggregate in terms of its ability to resist crushing.

Quartzite: Metamorphic Rock - Pictures, Definition
What is Quartzite? Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz.It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism.. Metamorphism recrystallizes the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength.
