Scope

This document specifies the method outline for testing the strength of cement mortar (ISO method), laboratory and equipment requirements, the composition of mortar, the preparation of mortar, the preparation of test specimens, the curing of test specimens, the test procedure, test results, and the acceptance inspection of ISO standard sand and substitute equipment in China. This document is applicable to the flexural and compressive strength testing of cement mortar made from general silicate cement and limestone silicate cement. Other cements and materials can be used for reference. This document may not be suitable for the strength testing of some types of cement mortar, such as cements with a very short initial setting time.
