Concrete Repairs & Restoration Description: CONCRETE REPAIR & RESTORATIONrefers to the process of fixing a hardened concrete surface that over time has lost the ability to hold the binding concrete materials together due to damage or environmental exposure. It's used to fix cracks, physical impacts, chipped out surfaces or surface scaling, and can prolong the life of a structure well beyond its original design life. Small improvements to the concrete's quality and rigidity pays off in the long term, reducing the need to demolish and rebuild structures that could otherwise be saved.But why does a material as durable as concrete deteriorate? A number of reasons. The primary cause of concrete damage is the corrosion of reinforcing steel and other embedded metals. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling. Corrosion can also occur due to carbonation, the structure's passivating layer being destroyed, dissimilar metals mixing, freeze-thaw deterioration, deicer scaling, aggregate expansion, attacks by acids/alkalines/salts/sulphates, abrasion, erosion, overload, damage by ,production operations or vehicular traffic, and more. Abrasion damage can also happen in hydraulic structures where the abrasive effects of waterborne silt, sand, gravel, rocks, ice, and other debris impinge on the concrete surface. Additionally, when exposed to fire or unusually high temperatu...
