3 Principle
The change in height of a rammed sample of paste is measured at temperatures increasing to 950 C, with a holding period of 3 h at the highest temperature, The shrinkage of the paste between the temperature at which the paste has become non-plastic and at 950 C (both before and after the holding period) is determined.
