Concrete - What to do dusting, crumbling, cracking and discoloration

Concrete is one of the most common materials used in modern construction, the reason for this is that there is no other material can be concrete, the same results. The use of concrete for the building has great advantages such as simplicity and strength. With concrete has been years in liquid form, it is very easy to use, but when it dries it gives incredible power in the past. Despite the fact that a concretegreat source of building material for everything from concrete floors, foundations, bridges and tunnels, it might be time, some problems with the concrete to the end. Some problems that may occur include the overall strength of the concrete itself, and corrosion of concrete exposed to excessive moisture, as well as the composition of the soil may also cause some problems around it. Not only are the poor quality of materials and improper concrete are expensive then, but it can also be dangerous if the result will be to reduce the resistance of the concrete. To avoid these problems, we recommend high-quality concrete and concrete only remain vigilant for possible problems with this. Some common problems are concrete,

Dusting: the concrete surface forms a loose powder, which shows that the surface of> Concrete disintegrates. This may be the treatment of the water drain in concrete a. In this way, the concrete relationship with a high water content, leading to a weakening of the surface. Other causes of this specific problem can help with heating during the cold working without adequate ventilation, carbon dioxide may be excessive, leading to charring or so of concrete to freeze the surface.



Chipping & Peeling: The process of freezing and thawing of the finished concrete often results in flaking and peeling, some of the factors that contribute to this problem can not count on porous concrete, and is a must to protect the concrete from the effects of freezing and thawing. Also, if you use too much calcium chloride more like an accelerator, can also cause a problem with peeling and flaking. Some other situations that may lead to> Bow of concrete and the skin to include the treatment of the concrete surface too, inadequate care bleed water or antifreeze.



Cracks in the concrete surface: In some cases, the surface layer of concrete cracks can start to form a network of good. This problem is often caused when rapid drying has been used, or inadequate treatment of the concrete. Other factors may also water on the surface during the finish or the spread of cement to the surface water to bleed dry.



Cracking: the most common reason that the stress cracks in concrete expansion and contraction of the concrete without sufficient emergency vehicles s. This could be the result of an incorrect accession, withdrawal and settlement. Other contributors to this problem of freezing and thawing or external restraint, such as > Flooring.



Pick-up: Another common problem with concrete cracking due to shrinkage. This can occur if there is a rapid evaporation from the surface before the concrete has set.



reduced strength of the concrete: This can happen if the wrong casting, processing and treatment methods are used, other causes may also be the high air content, too much water, or an error in the production of> Concrete.



Delamination: This is a situation where there is a separation between the top plate and bottom plate of air or water can enter through a thin layer. Some situations that can cause this problem when the air is aerated concrete used for hard surfaces, sealing the surface, while it was still bleeding water is present, the revision of the surface, or with a vapor barrier of polyethylene.



Decolorization: Some of the most common causesDiscoloration of the concrete using calcium chloride twice the speed of the set, changes in mix proportions or material sources, unequal treatment.



Curling: Curling occurs when, in essence, what happens is that there is a distortion of the flat surface into a curved shape. This is often the result of a temperature difference of moisture between the top and bottom of the plate.



Spotty or uneven set of concreteThe most common cause of this problem is not the mixing of concrete at the bottom, and the use of some solvent with normal or retarders.

Many of these problems are common concrete construction can be avoided if the correct procedures and used as materials. It can help concrete additives, concrete lining to ensure a perfect, if they are installed correctly. So you should always buy your products from an expertConstruction chemicals supplier. Concrete sealing is an important aspect of maintaining a specific purpose a. These sealants are designed to inhibit fluids from concrete to absorb. In addition, these also to protect the concrete from water erosion, or freezing and substances such as salts and acids. for the laying of concrete to make the costly mistake, to avoid the additional costs of having to repair the concrete after aTime, you should always ensure that you are the best or concrete, and to follow the correct procedure for laying concrete.
