Four concrete cooling towers at a coal-fired electrical generation plant exhibited reinforcing steel corrosion that was causing concrete deterioration. This case study follows the repairs to those ...

Most slabs-on-ground are unreinforced or nominally reinforced for crack-width control. When positioned in the upper or top portion of the slab thickness, steel reinforcement limits the widths of ...

Consider the following case. Contract documents call for #6 reinforcing bars embedded in a concrete wall and with right angle bends that will be the top bars in a floor slab to be added later. But ...

Research is getting under way to develop prescriptive code language and performance-based design guidelines for a “rocking frame” structural system that relies on vertically post-tensioned shear walls ...

In hopes of producing concrete structures that can repair their cracks, researchers from Drexel University’s College of Engineering are putting a new twist on an old trick for improving the durability ...

In this video, I demonstrate how to create a large concrete slab from start to finish. CHAPTERS: 00:00 - Clearing the Area 01:30 - Surveying the Site 02:28 - Building the Frame 06:13 - Trench Filling ...

Reinforcing steel and ribbed reinforcement bars (rebars) are essential to civil engineering, forming a category of key structural materials which, in the case of concrete-reinforcing steel, are ...

Many bridges in Switzerland were built before the 1980s – and are therefore approaching the end of their service life. Empa researchers are now ...

The electrons produced during this process are conducted through the metal whilst the ions formed are transported via the pore water which acts as the electrolyte. Concrete as an Environment The ...
