Can I separate steel bars embedded in concrete using ...

2006-7-18  To re-phrase a question I asked before: In my back yard, there are some steel bars embedded in concrete, from the foundations of an old out-house. I want to remove the steel, and leave the concrete intact. I know I can cut off the steel, but I'm interested to know if I could (even theoretically) remove the steel bars intact, while only damaging the a small fraction of the concrete that ...

Types and Causes of Concrete Deterioration

2014-4-14  Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan-sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2).

Bearing Capacities of Different-Diameter Concrete

The bearing capacities of concrete-filled steel tubes are normally derived through experiments with small-scale specimens, but it is uncertain whether such derivations are appropriate for the much larger components used in practical engineering. This study therefore investigates the effect of different diameters (219, 426, 630, and 820 mm) on the axial compression of short concrete columns in ...
