Measurement of concrete strength. Traditionally, this is done by preparing concrete cubes or prisms, then curing them for specified times. Common curing times are 2, 7, 28 and 90 days. The curing temperature is typically 20 degrees Centigrade. After reaching the required age for testing, the cubes/prisms are crushed in a large press.
