    Chemical reaction of limestone with C3S and C3A | .

    Besides the reaction with C 3 S, limestone can reacts with C 3 A as well. According the investigation of Ingram et al., for a combination of 2% gypsum, 6% limestone, and 92% clinker, CaCO 3 reacts with C 3 A in the clinker. The reaction begins with a C 3 A·CaCO 3 ·12H 2 O product, then forms compounds containing a molar ratio of C 3 A to CaCO ...

    Weathering | What is limestone? | Limestone .

    Chemical weathering. Chemical weathering involves the decomposition of rocks due to chemical reactions between minerals such as calcite with water and gases in the atmosphere (e.g. carbon dioxide and sulphur dioxide). The solution of soluble minerals is particularly important in limestone landscapes.

    Difference Between Limestone and Sandstone | .

    14-10-2011· However, the biological sedimentary rocks are more abundant than chemical sedimentary rocks. In pure limestone, only calcite is there, but often they can contain impurities by mixing other materials like sand. So, limestone can be defined as a sedimentary rock, containing more than 50% of calcium carbonate in the form of calcite.

    What happens when acid reacts with limestone? | .

    Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
