Stones for construction are divided into. a) Pebble; b) Crushed stone. Type They can be divided into Type I, Type II and Type III according to the technical G1 Mass of dried samples before test, g; G2 Mass of dried samples after test, g Clay content is the arithmetical mean of two test .
For the uniaxial or unconfined compressive strength test a right circular cylinder of the material is compressed between the platens of a testing machine as illustrated in Fig. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the crosssectional area. Rock strength has been found to be size dependent because of the cracks and fissures ...

A complete suite of characterization tests were conducted on 16 aggregate materials with laboratory samples consistently prepared for a midrange densegraded base course gradation. The tests included imaging based aggregate particle shape analyses, moisturedensity, resilient modulus, shear strength, and permanent deformation. The concept of Shear Strength Ratio (SSR), defined as the ratio ...

The confirmation test results should be submitted within one week of collection of the sample. For stone sources ...
Stone Testing. For most tests, the stone specimens are tested dry. However, since the strength may vary when the stone is wet, the strength tests ( compressive strength, flexural strength, modulus of rupture) are sometimes performed using wet stone specimens. For the dry condition, the stone specimens are dried in an oven at 60°C. get price
