Accelerated weathering of limestone (AWL) can be used to capture CO 2 from effluent gas streams and store it as bicarbonate in marine environments. We give an overview of the fundamental aspects In the present study, the accelerated weathering of limestone was carried out using different sizes of limestone cuttings (4 mm, 500, 250, 100 and 50 µm) under Accelerated Weathering of Limestone for CO2 Mitigation

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide How does weathering affect limestone? Internet

This is called weathering. Scientists categorize the processes that break down rock in two groups: physical and chemical weathering. Physical (also called mechanical) weathering happens when forces (pushes and pulls) repeatedly act on the rock. An example is wind repetitively gliding against a rock taking rock particles with it.
