Precision of Early Shrinkage Measurements
A method has been developed for the determination of early shrinkage measurements of higher accuracy than previously attained. Its basis has been a consideration of thermal effects previously disregarded. Experiments have been devised in which movements due to thermal effects and drying shrinkage can be analyzed separately. Thus early drying shrinkage values can be determined without thermal shrinkage interference.
