Pit slope manual. Supplement 3-1, Laboratory classification tests .: M38-13/77-25E-PDF
"Tests for physical properties, index properties and uniaxial strength of the rock substance are described in this supplement. These tests are used mainly for classification; uniaxial strength may be used directly in stability analysis. The water content test is based on accurate weighing of a rock sample before and after oven drying. Porosity is determined by measuring the displacement in water of a sample sealed with paraffin wax. Swelling pressure and swelling strain indexes are measured in an apparatus similar to the soil consolidation test machine. The slake durability index measures the disintegration of a sample when agitated during two cycles of drying and wetting. Uniaxial strength and failure strain are determined from stress-strain measurements while loading to failure. The point load strength index is measured in an apparatus that subjects the specimen to opposed point loads. Tensile strength is determined from the Brazilian test"--Abstract.
