The cementitious component of lime is effective calcium oxide and magnesium oxide, and its content is the main indicator for evaluating the quality of lime. The content of effective calcium oxide and magnesium oxide in lime can be directly determined, and can also be reflected by the total amount of calcium oxide and magnesium oxide and the content of carbon dioxide, the requirement of raw lime and undigested residue content; the fine powder has the requirement of fineness; The hydrated lime powder also has requirements for volume stability, fineness and free water content. The national building materials industry divides the construction of quicklime, building lime powder and architectural slaked lime powder into three grades of superior and qualified products. However, in the transportation department, JTJ 034-2000 "Technical Specifications for Highway Pavement Base Construction" still divides quicklime and slaked lime into three grades according to the original national standard (GB1594-79).
