Investigation of Corrosion and Cathodic Protection in Reinforced Concrete. I: Application of Electrochemical Techniques

The electrochemical behavior of steel reinforcement in conditions of corrosion and cathodic protection was studied, using electrochemical impedance spectroscopy (EIS) and compared to reference (noncorroding) conditions. Polarization resistance (PR) method and potentiodynamic polarization (PDP) were employed as well, in addition to ac 2 pin...

Electrochemical Behavior, Microstructural Analysis, and Morphological Observations in Reinforced Mortar Subjected to Chloride Ingress

The behavior of steel reinforcement was studied using electrochemical impedance spectroscopy (EIS) and polarization resistance (PR) techniques in conditions of chloride-induced corrosion in ordinary Portland cement-mortar specimens immersed in 7% NaCl for a test period of 120 days and compared to specimens immersed in demineralized water for the...

Single Fibre Pullout from Hybrid Fiber Reinforced Concrete

Hybrid fiber reinforcement can be very efficient for improving the tensile response of the composite. In such materials, fibers of different geometries can act as bridging mechanisms over cracks of different widths. The fiber bridging efficiency depends on the interface properties, which makes interface characterization very important. Therefore...

Analysis of temperature stresses in concrete breakwater elements: Hollow cubes and Tetrapods

In this report, the results of a numerical parameter study on temperature stresses caused by hydration of cement in concrete breakwater elements are shown. Two different geometries were analysed namely hollow cubes and tetrapods. The problem encountered in solid cube breakwaters is the undesirable temperature build up between the core and the...

Golfdemper op basis van eindige differenties

De vervormingen in continue constructies kunnen worden beschouwd als een gesuperponeerd golfverschijnsel. Kenmerkend voor iedere golf is dat een verschijnsel zich verplaatst met een bepaalde voortplantingssnelheid. We beperken ons hier tot eendimensionale mechanische constructies waarbij een golfverschijnsel zichtbaar is als een vervorming,...

Induction heating of mastic containing conductive fibers and fillers

The objective of this research is to examine the induction heating of mastic through the addition of electrically conductive fillers and fibers (graphite and steel wool), and to prove that this material can be healed with induction energy. The effect of fibers content, sand–bitumen ratio and the combination of fillers and fibers on the induction...

Discussion on elastic compressive-flexural-torsional buckling in structural members

The article of Raven, Blaauwendraad and Vambersky in HERON 53, No. 1 discusses stability checking of torsional buckling in structural members loaded by compressive forces and bending moments. Unfortunately, many important issues are not considered and need to be commented on.
