Image‐based quality control – part 2: granulometric properties The changes in concrete technology necessary to achieve the climate protection targets will lead to a significant change in the concrete mixtures typically used. The raw materials used are becoming more diverse and complex. The use of recycled raw materials will also significantly increase the fluctuations in the properties of the raw materials. An Accurate and time‐efficient determination of the granulometric properties of the aggregate is of crucial importance, especially for "eco‐concretes", in order to ensure consistent quality characteristics. As a natural raw material, the aggregate is subject to certain fluctuations to which such optimized concrete compositions can react relatively sensitively. In the future, it will be necessary to determine possible quality deviations of the fresh concrete resulting from fluctuations in the raw materials in a time‐efficient manner in order to be able to make appropriate adjustments in the production process as quickly as possible. This paper presents an image‐based quality control for the digital evaluation of granulometric properties of the aggregate as a part oft he flow table test. Accordingly, the range of properties of the image‐based method already presented in Part 1 of this paper is extended to a fully comprehensive digital quality control. This paper presents the image‐based determination of the granulometric properties of the aggregate as a part oft he flow table test. The determination is based on the image‐based quality control described in part 1 of this paper. [ABSTRACT FROM AUTHOR]

Debris flow actions on concrete bridge superstructures Bridge structures in alpine areas are subject to various hazards. These also include debris flows. Debris flows events demonstrably also lead to the destruction of bridges. In order to design bridges for such hazards, information on the impact force of debris flow is necessary. For debris‐flow impacts against piers, extensive miniaturized as well as real size tests are available. So far, no such tests are known for bridge superstructures. In this paper miniaturized debris‐flow impact tests on concrete bridge cross‐sections are presented. Based on the test results, recommendations for the design of concrete bridges in exposed locations are proposed. [ABSTRACT FROM AUTHOR]

Traffic Monitoring on a Highway Bridge – Data collection on local traffic characteristics as a basis for site‐specific traffic load models Developing site‐specific traffic load models for individual bridge structures based on local traffic data represents a potentially effective tool for existing road bridges with remaining calculative deficits when assessed according to current codes (guideline for assessment of existing structures, "Nachrechnungsrichtlinie"). A robust data basis to represent the local traffic characteristics is essential for this purpose. This paper presents investigations carried out during a long‐term monitoring campaign to comprehensively describe the traffic load on a selected bridge structure along Federal Highway A 92 over a period of one year. For the campaign, a measurement unit consisting of a laser scanner and a webcam, and structural monitoring with the application of bridge weigh‐in‐motion (BWIM), are used. Suitable strategies and concepts for collecting, processing, and evaluating all available measurement data enable a comprehensive collection of all parameters relevant for traffic load modeling and thus provide a data basis for detailed and realistic modeling of local traffic characteristics. Initial evaluations of the monitoring data for selected parameters and the comparison with otherwise typical assumptions from the literature in case of missing parameter information show partly significant differences to the extreme traffic characteristics underlying the load models in codes.

Nonwoven bonded pre‐applied waterproofing membranes – bond development and properties Pre‐applied bonded membranes are used as an additional waterproofing measure on waterproof concrete structures and are installed before concrete placement. They achieve a bond to the fresh concrete and often use nonwovens, which must be filled with cement paste during concrete placement. However, little is known about the separation of cement paste from fresh concrete, its properties in the nonwoven, or beneficial nonwoven characteristics. The following paper analyzes the bond of nonwovens in three parts: first, the deformation behavior of the nonwovens during concrete placement is determined using microsections. During concrete placement, the nonwovens are compressed and progressively recover during cement paste filling. As the fresh concrete is placed, filtration processes start. Excess water and a limited amount of fine solids separate into the nonwoven. A filter cake forms on top of the nonwoven and is responsible for a water‐rich cement paste within the nonwoven. Only with the onset of vibration compaction is the filter cake loosened, more solids penetrate the nonwoven, and the water‐solid ratio in the nonwoven is lowered. The bond subsequently develops proportionally to the tensile splitting strength of the concrete. Nonwovens influence the bond strength as they control the separable amount of excess water, which degrades the cement paste strength in the bonding layer. [ABSTRACT FROM AUTHOR]
