If you want a lifelong job, it might be painting on the Sydney Harbour Bridge - once you're done, you may have to start again from the other end. In order to prevent the corrosion of the steel, the paint continues to be sprayed, and the corrosion of the steel is the cause of the corrosion of the concrete. Others are called concrete corrosion or spalling.
How does concrete rot '?
Concrete is used in many commercial and residential buildings for many applications such as slabs, stairs, columns and columns, support beams, balconies and corridors, walls, passageways and pools. A large amount of concrete involves structures such as bridges, piers and high-rise towers. Concrete is usually reinforced with steel or mesh and, in larger developments, requires a large amount of steel to increase strength.
The enemies of reinforced concrete are water and air. If these elements can enter the closed steel in the concrete, it will corrode - the steel will expand when it breaks and the surrounding concrete will rupture. As the concrete cracks and breaks, the chances of water and air coming into contact with the steel bars are greater and the process is intensified. Due to the reduced structural integrity of concrete, there are significant safety issues.
How to identify concrete decay
It may not be visible in concrete, but as it continues, it becomes more visible. You may notice rust on the concrete, or the concrete peels off, cracks or breaks. In extreme cases, most of the concrete will fall, exposing rusted steel. Remedial treatment can involve a large number of expensive corrective actions.
Professional building inspections can identify problems or warn of possible future problems. It may be a pool in some places, a small crack in the concrete or a reinforcement too close to the concrete surface. Prevention is definitely better than curing with concrete rot - it may be just a matter of improving drainage, smearing the surface or sealing the crack with some kind of mortar or epoxy packing. If you have any doubts about concrete decay, you can get some expert advice.
I like to be at the seaside
Yes, most of us do this, but here concrete rot may be more common because the chloride in the moist salty air reacts more strongly with the steel. Concrete rot is a problem that has always existed close to the ocean, and property owners need to constantly look for signs of deterioration and ensure that protection measures are maintained.
The same is true for chlorides associated with swimming pool chlorine or sea water pools.
In addition, there is often moisture near the ground in the waterfront neighborhood, and water can be absorbed into the structure. Large buildings with basements or underground parking lots may experience the same problem of groundwater seepage.
In short, concrete decay is a common problem. It can cause severe structural damage, which can be difficult to repair and expensive. It is not always easy to detect, it can lead to serious safety hazards and can be avoided by obtaining expert advice and using the right materials and proper construction guidelines.
