Additionally, spalling concrete might pose a serious safety hazard to the general public as well as to the physical property. Especially, if the spalling parts are located overhead, for example, edges of balconies, parapet walls, entrances, archways and bridges. To prevent accidents and to ...
Concrete is marvelous stuff but in time it will deteriorate. When it does, you either have to patch it or replace it. Assuming that it is structurally sound, the least expensive alternative is to patch it. However, patching it requires some attention to detail or your patch will not last....
The results of a recently finished research project have shown a great influence of the amount of polypropylene (PP) fibers on the spalling behavior of concrete under fire loading. Starting from the identification of the permeability as the parameter with the greatest influence on spalling, results...
Posts stand under the deck beams and transfer the load of the structure to concrete footings sunk in the ground. Local building codes may dictate minimum post sizes and spacing to ensure safety. The height of the deck will also influence post size requirements, as larger posts can handle great...
