Modellierung von Bewehrungskorrosion — 400 zu Rissbildungen und Abplatzungen. Evaluation of the time dependent behavior of concrete. Petersburg, Russland,Heft dafdtb, S. Rather, emphasis must be placed on proper composition, compaction, and lateral sealing of the hydraulically bonded layer HBLin order to prevent washing-out of fines by dafstv water to an extent which could lead to significant damage by structural loosening.

Zum Risiko der Schwindrissbildung in Betonbauteilen aus Hochleistungsbeton. Sulfatangriff auf Beton — Mechanismen und Prognosemodell. A fracture mechanical investigation of the fatigue behaviour of concrete under tension. As a result, it is not probable — with the concrete cover and the concrete quality as applied in such cases — that spalling of the concrete could take place as a result of volume increase caused by the products of corrosion.

In this context, there is a great spread in the values encountered for concrete tensile strength, the characteristics of the bond between steel and concrete, and the corrosion depth at the reinforcement as a result of corrosion in the cracks. As only a small fraction of the lattice truss reinforcement can demonstrate corrosion and, if so, only on a locally limited basis, the reinforcement remains properly integrated in the concrete layer, and the serviceability of the system is guaranteed during the intended life cycle.

Owing to the large spreads encountered in crack widths, application of the above stated design value implies the following: Stoffgesetze zur Vorhersage des Kriechens von Beton. Creep and shrinkage characteristics of ultra high strength concrete UHPC.

Increasing the crack width by a factor of two, results in hect the carbonation rate in the crack by a factor of four. Experimental and numerical hfet on crack development in a concrete slab subjected to thermal shock. Comment on recent analysis of concrete creep linearity and applicability of principle of superposition.

Especially in conjunction with chloride-induced corrosion in a crack, considerable significance must ultimately be attributed also to the aspect of high anodic polarisation resistance. Carbonic acid will in turn react with the calcium hydroxide, Ca OH 2, of the concrete pore water solution to produce calcium carbonate, CaCO3, accompanied by release of water.
