High-Temperature Self-Healing Geothermal Cement Composites


A presentation with notes showing an overview of the last 6 months of the project on high-temperature self-healing inorganic cement composites. General approach, test methods and results for the self-healing cement composites are presented. Data include strength recoveries for 9 cement composites in three curing environments (water, alkali carbonate, brine) at 300 degC, bond strength measurements for cement/carbon steel samples, thermal shock tests, performance of healing aids. The presentation was shown during the joint SPE/GRC workshop on March 22 in San Diego, California
