Mixing, Moulding, Curing and Strength

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.

This machine consists of a mould table seated on a rotating cam driven at 60 revolutions per minute. The apparatus is supplied with a remote mains switch box, incorporating a push button start/stop control, and automatic stop control at end of test.

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.

Prior to testing, EN 196 requires prisms to be cured for a period of at least 24 hours at 20 ±1ºC, 90 % 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.
