TY - CONF A1 - Ebell, Gino A1 - Breit, W. T1 - Investigation of corrosion product layers in chloride containing mortars - "galvanized reinforcement" N2 - In the case of galvanised steel in mortar or concrete, the corrosion behaviour depends on the ion distribution of the pore solution and the pH value. Therefore, a new approach has been developed to determine the corrosion behaviour by single frequency AC measurements and to determine the B-values to calculate the corrosion current density using the Stern-Geary equation.

T1 - Interrelated Data Set from Nondestructive and Destructive Material Testing of Concrete Compressive Strength Specimens N2 - "This data set contains three different data types obtained from concrete specimens. For each specimen, the rebound numbers, ultrasonic data (ultrasonic velocity, time of flight), and destructive concrete strength are given. Two kind of specimen geometries were tested: cubes and drilled cores. The files are labeled according to the specimen geometry as "cube" or "core" and the type of measurement data as "compressive_strength", "rn_R" and "rn_Q" for rebound numbers as well as "us" for ultrasonic data. The ultrasonic data were generated by six independent laboratories, the rebound numbers by five independent laboratories and the destructive tests by one laboratory. The designation of each specimen establishes the relationship between the different data types."
