一般的な説明
Mortar is distinguished from concrete by the maximum size of its aggregates. In general, mortar contains only sand with a maximum grain size of 2 – 4 mm. Other binding materials such as hydraulic lime can be used in addition to cement. In concrete construction, cement mortars are used for connecting precast elements, as injection mortars in ducts of posttensioned structures with bonded tendons, and for the repair of old concrete surfaces with areas of deterioration.
