Concrete – What to Do About Dusting, Crumbling, fractures and Discolourat…

Concrete is one of the most shared materials used in modern construction; the reason for this is that there is no other material that can provide the same results as concrete. The use of concrete for construction provides some great advantages, such as ease of use and strength. When concrete is in it’s liquid form it is very easy to use, but when it dries it provides incredible strength that will last for years. Despite the fact that concrete is a great source of construction material for everything from concrete floors, to building foundations, bridges and tunnels, there could be some problems with the concrete over time. Some issues that may arise include the overall strength of the concrete itself, in addition as corrosion due to the concrete being exposed to excessive moisture; in addition, the surrounding soil composition could also cause some problems. Not only could low quality materials and improperly mixed concrete be costly later, but it can also be dangerous if the consequence diminishes the concrete’s strength. To avoid these problems it is advisable to always use high quality concrete and to stay vigilant for possible problems with the concrete.Some of the most shared concrete problems include,

  • Dusting: The surface of the concrete will form a loose powder, which indicates that the surface of the concrete is disintegrating. This can be caused by water bleeding into the concrete during finishing. This may cause the concrete to have a high water ratio, leading to a weakened surface. Additional causes of this concrete problem may include using heaters during a cold weather operation without adequate ventilation, which may cause excessive carbon dioxide, leading to carbonization, or allowing the surface of the concrete to freeze.

  • Flaking & Peeling: The halting and thawing course of action of finished concrete often causes flaking and peeling; some of the factors that may contribute to this problem include, not using air-entrained concrete, which is a must to protect the concrete from the affects of halting and thawing. In addition, if there was too much calcium chloride used as an accelerator, this may also cause a problem with peeling and flaking. Some other situations that may cause concrete to flake and peel include working the surface of the concrete too much, insufficient curing, water bleed, or using deicer.

  • Fine fractures in the Surface of the Concrete: In some situations the surface inner of concrete may begin to form a network of fine fractures. This problem is often caused when a rapid drying procedure was used, or there was inadequate curing of the concrete. Other contributing factors may include water on the surface during finishing, or the sprinkling of cement on the surface in order to dry the water bleed.

  • Cracking: The most shared reason that concrete fractures is due to the expansion and contraction of the concrete without s sufficient method of relieving stress. This could be the consequence of improper jointing, shrinkage, and settlement. Other contributors to this problem include halting and thawing, or external restraint, such as flooring.

  • Shrinkage: Another shared problem with concrete is cracking due to shrinkage. This may occur when there is a rapid evaporation of the surface before the concrete has set.

  • Reduced Strength of Concrete: This can happen when improper casting, handling and curing procedures are used; additional causes may include high air content, too much water, or an error in the manufacturing of the concrete.

  • Delamination: This is a situation where there is a separation between the top slab and bottom slab that may be caused by a thin inner of water or air. Some situations that may rule to this problem include when air entrained concrete is used for hard finishes, sealing the surface while there is nevertheless bleed water present, overworking the surface, or using a polyethylene vapor obstacle.

  • Discoloration: Some of the most shared causes of concrete discoloration include using calcium chloride to speed set times, changes in the mix dimensions or material supplies, rough curing.

  • Curling: When curling occurs, essentially what happens is that there is a distortion of the flat surface into a curved shape. This is frequently the consequence of a difference in the temperature of the moisture content between the top and bottom of the slab.

  • rough or Spotty Setting of Concrete: The most shared cause of this problem is not mixing the concrete thoroughly, and the use of some superplasticizers with normal setting or retarding admixtures.

Many of these shared concrete problems can be avoided when the proper procedures and materials are used during construction. Concrete admixtures can help to ensure a perfect concrete finish, if they are used correctly. This is why you should always buy your products from an experienced construction chemicals supplier. Concrete sealant is an important aspect of preserving a concrete finish. These sealants are designed to hinder liquids from being absorbed by concrete. In addition, this will also help protect the concrete from water erosion or halting, in addition as from substances such as salts and acids. Making mistakes when laying concrete can be very costly; to avoid the additional expense of having to repair the concrete at a later time, you should always ensure that you use the best concrete products obtainable, and that you follow the proper procedure for laying concrete.
