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.

Matrix Strength Recovery After Repeated Damage for Aged Samples.JNB Unknown 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).

Cement Composites Modified with Pozzolanic Additives.JNB Unknown 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. Open resource
Cement-Carbon Steel Bond Strength and Young's Modulus.JNB Unknown 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. Open resource
Corrosion and Mechanical Properties of Calcium-Phosphate-Based Cements.JNB Unknown Economical chemical cement tested for carbon steel corrosion protection, bond strength and matrix self-healing Open resource
