High-Temperature Inorganic Self-Healing Inorganic Cement Composites

Description

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.

0 Economical chemical cement tested for carbon steel corrosion protection, bond strength and matrix self-healing https://gdr.openei.org/files/978/Corrosion%20and%20mechanical%20%20property%20CaP-Fondu.JNB
0 Data showing matrix strength recovery after repeated damage (2 crushes) for cement composites originally cured in water or alkali carbonate at 270 degC for 1, 5 or 10 days. The strength and Young's modulus 5-day recoveries are reported for alkali-activated cement (TSRC: Calcium Aluminate Cement/Fly Ash F/Sodium metasilicate), chemical cement (CAP: Calcium Aluminate Cement/ Sodium hexaphosphate), Portland cement (class G/silica flour) and slag modified with sodium metasilicate (SSAS). https://gdr.openei.org/files/967/DOE%20data%20repository-TP.JNB
0 Data showing compressive strength and Young's modulus data for inorganic cement composites modified with 3 clay-type additives after a day curing at 300degC in water or alkali carbonate solution and their recovery after repeated crush damage followed by two 5-day healing periods in these environments at 300degC. The composites included thermal shock resistant cement (alkali activated calcium-aluminate cement blend with fly ash F) and class G well cement modified with silica flour. The additives included bentonite, Metakaoline, and Montmorillonite. They were added at 5% by total weight of cements. https://gdr.openei.org/files/967/Pozzolanic%20additives.JNB
33 Document summarizing types of samples and types of tests conducted on each cement type. The cement types include alkali activated cement, chemical cement, and Pozzolanic cement, and Portland-cement-based formulations. Tables summarizing results include composite name, cement, Pozzolanic additive, activator, additives, tests performed, and references for each type o0f cement. https://gdr.openei.org/files/979/Cement%20formulations%20tested%20by%20BNL%20for%20self-healing.pdf
0 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. https://gdr.openei.org/files/967/Self-adhering%20cements%20by%20MGF%20%283%29.JNB
