Rock and weathering

Weathering is the breakdown of rocks in situ (in the place where they are). Rocks are susceptible to weathering. The type of weathering that is most effective is determined by the composition of the rock and the climate. There are three main types of weathering. These are mechanical, chemical and biological weathering. Mechanical Weathering.

8-4 σt = 2P / ( π d t) (8.1) Generally the Brazilian test is found to give a higher tensile strength than that obtained in a direct tension test, probably because of the effect of fissures in the rock. Another method of determining tensile strength indirectly is by means

Unconfined Compressive Strength Test of Rock

 · This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. Unconfined Compressive Strength Test …

Weathering & Erosion

During transportation of the weathered rock materials, the angular particles commonly abrade (rub or scour) the surfaces over which they pass, wearing away and lowering the rocks. Thus, landslide debris may erode the slope or channel along its course, the sediments in rivers erode the rocky sections of their beds, and the rock fragments in glaciers erode the valley floor.
