Shaking Table Model Test on the Dynamic Response

Stability prediction of rock slope under seismic loads is important for landslide hazard assessment. For studying the dynamic response of anti-dip rock slope, one two-dimensional physical model of anti-dip slope containing two groups of rock joints was designed for shaking table test.

Pelagic barite precipitation at micromolar ambient

Introduction. The size and turnover rate of the marine sulfate reservoir is fundamentally linked to the global biogeochemical cycles of oxygen, nutrients, and carbon 1.Since barite (barium sulfate, BaSO 4) can record the input 2, inventory 3, and internal cycling 4 of sulfate within the marine reservoir, the chemistry of sedimentary barites offer a powerful means to study the history of

Barite powder as sand substitution in concrete: Effect

Mean dimension is the average size through which the particles pass and the sieve size on which these are retained. For example, mean size of the particles passing through 25 mm sieve and retained on 20 mm sieve is (20+25)/2=22.5 mm. if the least dimension is less than 3/5 x (22.5) = 13.5 mm, then the material is classified as flaky.
