The Most Common Causes of Concrete Degradation And Avoid Itadmin
Concrete degradation is the course where the concrete loses its toughness which makes it more susceptible to damage. Causes of concrete degradation varies from fire, sea water effect, aggregate expansion, corrosion of reinforcement bars, chemical damage (such as carbonation, leaching, and decalcification), bacterial corrosion, physical damage, thermal damage and radiation damages.
Though concrete is generally considered as one of the most hard-wearing raw materials for building construction, the risk of material degradation still exists.
Engineers can employ different measures in order to moderate the adverse effects of concrete degradation on structures and properties. Degradation of concrete caused as a result of chemical damage certain components may be added to the concrete to cushion the harm. To prevent corrosion of concrete reinforcement, engineers could also consider adding fibers in the concrete to reduce the corrosion and rusting.
Furthermore, adding fibers can reduce and prevent concrete fractures. These fibers can improve the effect of the wire mesh that keeps the cracks from deteriorating.
Concrete hardener such as Costar Repair Mortar 10 is another cementitious additive that may also protect the concrete from water, salt, and chemical acid interference that commonly results to efflorescence. Chemical acids dissolve and soften the cement, which is an ingredient of concrete. Efflorescence, also can harmfully affects the concrete materials because of the salt that infiltrate its surface.
During rainy season, concrete is at risk of damage physically because it is a porous substance. Water penetrates the concrete during the rainy season. When this happens, it expands and adds pressure to the material that can fracture the concrete. This additional pressure exceeds the concrete strength and results to this phenomenon.
Air entraining admixtures can be added to the initial mixture to prevent this occurrence from happening. These agents create minute air pockets in the concrete. When the water inside the concrete ices up and solidifies, the frozen water will expand to the air bubbles rather than affecting the material itself. This eliminates the risk of damaging and cracking the concrete because of the expansion of frozen water. Concrete hardeners can also be used in order to counteract future freeze-thaw injuries and water penetration.
Elimination of the risk of physical breakdown is totally impossible for concrete since it is always subject to pressure and extreme weight. However, constructors can employ techniques to minimize the appearance of the effects of wear and tear. They can use sand blasting and diamond grinding in order to even out scratches and clumps in the concrete material. Sealers for concrete maintenance can also be used to put protective coating over the surface abrasions in the concrete.
Having a thought regarding the reasons of concrete degradation and how to abstain from misery harm from these is valuable to amplify the utilization of the material. It is likewise recommended that purchasers counsel the specialists in regards to the utilization of concrete with a specific end goal to acquire a more far reaching thought of how to protect the material. Like what a well known saying states, it is more beneficial to avoid harms as opposed to search for approaches to take care of issues after they have happened.
