High-Temperature Inorganic Self-Healing Inorganic Cement Composites Self-adhering cements by MGF (3).JNB

The data files below summarize the results from various experiments testing properties of high-temperature self-healing inorganic cement composites. These properties include cement-carbon steel bond strength, Young's modulus recovery, matrix recovery strength, and compressive strength and Yonug's modulus for cement composites modified with Pozzolanic Clay additives. Bond strength data for cement composites adhering to carbon steel cured for 1 day at 300degC in three different environments (water, sodium carbonate, geothermal brine), de-bonded and healed for 5 days at 300degC in the same environments. The original (before the de-bonding) and recovered bond strengths and Young's modulus are reported for alkali activated cement (TSRC: Calcium Aluminate Cement/ Fly Ash F/ Sodium metasilicate), chemical cement (CAP: Calcium Aluminate Cement/ Fly Ash F/ Sodium hexaphosphate), Slag-based- and Portland-based cements (class G modified with silica) and for these composites modified with 5 or 10% of Micro Glass Fibers (MGF). The original composites and 5% MGF-modified composites also included 10 or 5% (respectively) of Micro Carbon Fibers (MCF) to control crack formation and propagation.
