Effect of relaxation on eigenstresses and microcracking in concrete under imposed deformation

For the dimensioning of concrete structures it is customary to determine the forces and stresses occurring in construction elements on the basis of the prescribed loads. In an iterative process, the final dimensions of the elements and reinforcement are then determined. This process becomes less simple if not only the external loads, but also...

Effect of Young’s modulus on the degradation of repair mortars chloride migration resistance under coupled loading conditions

The chloride migration coefficient is the most important material parameter for the service life prediction of reinforced concrete structures in exposure to chloride. For a comprehensive and precise prediction of the service life, however, further effects such as load-induced microcracks must be taken into account. Currently coupled effects like...

Bacteria-initiated self-healing concrete: Influence of chloride ions, carbonation and mechanical load

Under service conditions and because of environmental and climate changes, the concrete is at risk due to crack-induced durability problems. The consequences can be even more pronounced when concrete is exposed to specifically aggressive environmental conditions. This has been portrayed by rapid deterioration of relatively young concrete...
