The results of strength testing of cement and other materials such as Lime and Fly Ash are dependent on the method and the quality of equipment used. A standard system for strength testing is based on compressive strength of mortar prisms. The results of strength testing are dependent not only on method but also on the quality and accuracy of the testing machine used to determine compressive or flexural strength.

The successful preparation and moulding of prisms, cubes and briquettes is essential if subsequent strength tests on the specimens are to be meaningful. Moulds should be manufactured from material which is capable of retaining its form under heavy usage. The equipment detailed in this section has been designed and manufactured to meet the requirements for moulding laid down in the various standards.

Two methods of moulding and compaction are used in the various testing standards. The jolting table method is usually described as the reference method and a vibratory method is permitted as an alternative.

Prior to testing, EN 196 requires prisms to be cured for a period of at least 24 hours at 20 ±1°C, 90% RH minimum. The prisms are then demoulded and stored under water for the required curing time, usually 48 hours, 72 hours, 7 and 28 days.

Prior to testing, ASTM C109 requires prisms to be cured for a period of at least 24 hours at 23ºC ±2ºC, 95 % RH minimum. The prisms are then de-moulded and stored under water for the required curing time, usually 48 hours, 72 hours, 7 and 28 days.
