Angle of repose Wikipedia

Angle of repose WikipediaThe angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the material affects the angle of repose; smooth, rounded sand grains cannot be piled .

What is the bulkage of fine aggregate? Quora

What is the bulkage of fine aggregate? QuoraJan 19, 2019· Bulkage or bulking of fine aggregate sand is nothing but the increase in the volume due to presence of water. When water is added or comes in contact with sand, first sand absorb it and then the water is coated on its surface which is termed as adsorb water. Adsorb water creates surface tention which push sand particals apart from each other.
