“…The impacts of dissolution on rocks are mainly reflected in the formation of the strength, dissolved pores, cracks, and surface roughness on the surface [103,[114][115][116][117]. The components that can react with fluids will continuously decrease as the dissolution process progresses which leads to changes in rock mineral composition.…”

Leaching in cement-based materials and dissolution in rocks are important problems in civil engineering. In the past century, concrete damage caused by leaching have occurred worldwide. And, rock dissolution is usually the main cause of karst rock erosions. This paper provides a review of the causes, influencing factors, and effects on engineering properties of dissolution of rocks and leaching of cement-based materials. The applied experimental methods for leaching and dissolution have been sorted out and discussed. In situ field experiments can be used to study dissolution under natural conditions, while the laboratory experiments can effectively shorten the experiment time length (by changing pH, temperature, pressure or other factors that affect the leaching or dissolution) to quickly investigate the mechanism of dissolution and leaching. Micro tests including XRD, SEM, EDS, and other testing methods can obtain the changes in material properties and microstructures under leaching and dissolution. In addition, with the advances in technologies and updated instruments, more and more new testing methods are being used. The factors affecting the leaching and dissolution include environmental factors, materials, and solvent parameters. The mechanisms and deterioration processes of leaching and dissolution varies according to the types of material and the compositions.

“…After dissolution, the porosity usually increases continuously, leading to the connection between pores in rocks [118,119], and the permeability of rocks may increase several times or even tens of times [116]. But, in some cases, the permeability of rocks may actually decrease.…”
