Strength development and hydration progress of a cement-based solidifying agent used in cementtreated soil containing volcanic mineral components

This study investigates the relationship between the strength development and hydration progress of cement-based solidifying agents (CBSAs) in cement-treated soil with volcanic mineral components. A CBSA is a cement-based material used as a soil stabilizer. It is known that the strength development of cement-based materials is inhibited by...

Analytical study about the expansion progress of concrete exposed to combined alkali silica reactions and freezing thawing cycles

Using numerical simulations, this study investigated the concrete expansion damage caused by the coupled action of freeze-thaw cycles (FTC) and alkali silica reactions (ASR). In the authors’ previous experiments, it was shown that a preceding ASR definitely accelerated the succeeding expansion by FTC. Further, even if the specimens have...

Increase in critical stress for crack-healing of Si3N4/SiC ceramics by shot peening

The effects of shot peening on the critical stress for crack-healing of Si3N4/SiC composite ceramics were investigated. Shot peening was carried out on a Si3N4/SiC composite with a surface crack by using yttrium-stabilized zirconia beads. Shotpeened specimens were crack-healed at 1100 °C for 5 h under a tensile stress (?app) in the range 0–500...
