Abstract

This paper discusses the design and development of an automated test device for measuring the chemical shrinkage of hydrating cements. The device uses a very sensitive pressure sensor to determine water level drop in an open capillary tube, from which the volume change due to chemical shrinkage can be calculated continuously. The repeatability of the measurements and the stability of the measuring device have been demonstrated. The comparison of the result produced by the new device with that of a standard ASTM test showed excellent matching. The range of applicability of this device was demonstrated by obtaining shrinkage measurements for different types of cements, such as ordinary portland cement, Class H oil well cement and white portland cements, and for different temperatures.
