Impact of drying on concrete and concrete structures

RILEM Technical Letters, 2022
This study reviews research showing changes in the performance of reinforced concrete structures and members caused by drying conditions, and aims to contribute to evaluating the structural safety in the long-term use of concrete. Additionally, to build a consensus on the changes in the physical properties of concrete materials after drying, the review

Elastic Stability of Perforated Plates Strengthened with FRP under Uniaxial Compression

Applied Sciences, 2017
Openings are frequently introduced in plates for the purpose of inspection, maintenance, service, etc. The presence of openings reduces the buckling and ultimate capacity significantly, and pasting fiber-reinforced polymers (FRP) is an ideal technique ...

Mechanical properties of aeolian sand cemented via microbially induced calcite precipitation (MICP)

Scientific Reports
The cementation of desert aeolian sand is a key method to control land desertification and dust storms, so an economical, green and durable process to reach the binding between sand grains needs to be searched. The method based on the microbially induced
