  • Deterioration of shear strength parameters of limestone ...

    2020-11-1 · Deterioration of shear strength parameters of carbonate joints under the influence of acid rainwater is a serious concern in rock engineering. Considering this, limestone specimens with planar joints (i.e. joints having roughness coefficient <5) collected from the Lanjiberna limestone mine (in the state of Odisha, India) were investigated.

    How are joints made in Limestone? As limestone is a permeable rock, water is able to seep down through the rock. Rainwater is a weak carbonic acid which reacts with the limestone dissolving the stone, enlarging joints and bedding planes. On the surface the chemical weathering widens and deepens cracks to form grykes. What are […]

     · Dissolution of the limestone or dolomite is most intensive where the water first contacts the rock surface. Aggressive dissolution also occurs where flow is focused in preexisting openings in the rock, such as along joints, fractures, and bedding planes, and in the zone of water-table fluctuation where groundwater is in contact with the atmosphere.
