Jun 01, 2020 · This value of T spall is close to the dynamic uniaxial tensile strength obtained for the investigated dolomite using the dynamic Brazilian test (UTS D = 44.6 MPa). Using the equations of elasticity for one-dimensional strain, the pressure P spall and σ spall can subsequently be obtained [ 20 , 23 ] using the known constants ( T spall , v ): (4.3) P s p a l l = T s p a l l 3 ( 1 + ν 1 − ν ) (4.4) σ s p a l …Cited by: 4
Sep 08, 2020 · Crushed dolomite used as artificial white sand can cause respiratory issues, warns DOH "Ito pong proseso ng pagka-crush ng dolomite, dun po tayo nagkakaroon ng hazardous event or effects sa katawan. As long as it is processed already, hindi na po ganun ang kaniyang epekto sa mga population o sa mga tao," DOH Undersecretary and spokesperson Maria Rosario Vergeire told ABS …预计阅读时间：2 分钟
May 01, 2020 · The fracture in experiments was initiated at the center of the specimen in each test. An immediate loading near the contact zone with 2 bars caused local crushing of the dolomite, which in some specimens resulted in a propagation of additional cracks after the main crack was generated.Cited by: 4

Dolomite (/ ˈ d ɒ l ə m aɪ t /) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for …
When using the Brazilian test to determine the indirect tensile strength of rock, it is usually assumed that failure is the result of the uniform tensile stress normal to the splitting diameter (see Figure 4a) and that the tensile strength, T o , is given by the value of F 3 (= -T o ) at failure
