Reliability of non-destructive testing methods by detecting the presence of reinforcement in existing concrete structures

, 2017
Information about the reinforcement in existing concrete structures is of great importance in order to determine the moment capacity. If the rebar drawings are available, then knowledge about the rebar could be derived from the drawings.

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

Effect of Post-Fire Curing on the Residual Mechanical Properties of Fire-Damaged Self-Compacting Concrete [PDF]

, 2016
Concrete is recognized for being a fire-resistant construction material. At elevated temperatures concrete can, however, undergo considerable damage such as strength degradation, cracking, and explosive spalling.

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
