3 Material Terminology

3.1 concrete It is prepared by mixing cementitious materials, coarse aggregate, fine aggregate, and water, as well as admixtures and additives as needed, in a certain proportion, and then uniformly stirring. Mixing is a building material formed through hydration. [Source: GB/T 43609.1-2023, 3.1]

3.2 Mortar A binding material made by mixing cementitious materials (such as cement), fine aggregates, water, or additives (optional). [Source: GB/T 43609.1-2023, 3.2]

3.3 dry mortar A material made by mixing cementitious materials (cement, gypsum, etc.), fine aggregates, or additives (optional), which hardens when mixed with water. [Source: GB/T 43609.1-2023, 3.3]
