Currently the shrinkage mold used to measure shrinkage as per the ASTM C157 test method is widely used, however, it does not allow for measuring of the shrinkage that happens in the first 24 hours (or in the case of ASTM C928, in the first 3 hours). The proposed device allows for measuring of shrinkage using specimen that is of the same size as currently used for ASTM C157 measurements.
