This International Standard specifies a method of determining the compressive and, optionally, the flexural strength of cement mortar containing one part by mass of cement, three parts by mass of ISO standard sand and one half part of water. The method applies to common cements and to other cements and materials, the standards for which call up this method. It might not apply to other cement types that have, for example, a very short initial setting time.
This International Standard describes the reference equipment and procedure, and specifies the method used for validation testing of ISO standard sands and of alternative equipment and procedures.
