Numerical Simulation of Mixed Mode Crack of Concrete: A Case Study Based on Experiment of Double Notched Specimen

Chloride ingress in cracked concrete studied using laser induced breakdown spectroscopy

Cracks are always present in reinforced concrete structures. It is a goal of the current research to study the influence of mechanical cracks on chloride ingress. A compact reinforced concrete specimen was designed, mimicking the cracking behaviour of beam elements. Cracks of different widths were induced by means of mechanical loading. These...

Bacteria-based self-healing concrete

A typical durability-related phenomenon in many concrete constructions is crack formation. While larger cracks hamper structural integrity, also smaller sub-millimeter sized cracks may result in durability problems as particularly connected cracks increase matrix permeability. Ingress water and chemicals can cause premature matrix degradation...
