Diagnostic Monitoring of the Physio-Chemical Processes in Hydrating Cement Paste



This paper details a novel electrical technique for monitoring the chemical and physical changes occurring within cement paste. The present study has concentrated on the initial 24 h after gaging with water and investigates the influence of retarders, accelerators, and cements of different type on electrical response. A microcomputer-controlled data acquisition system was developed to obtain results that can be used to obtain accurate electrical response/time curves. This is an advancement on earlier techniques. The work has correlated changes in electrical response with known chemical changes and structure building processes in cement paste. The method described also offers a technique for assessing the influence of chemical additives on the setting and hardening processes.
