Materials of poor quality along with concrete mixed improperly can turn to be costly when undertaking construction of any kind. Dangerous consequences can result too if the strength of concrete used is compromised. As such it is advisable to ensure utilizing high-quality concrete made by reputable companies like Bathurst Builders for instance to ensure getting the best outcome. There are many common problems that affect the concrete used during a particular construction initiative.
The concrete-surface will normally form some type of loose power, indicating it is disintegrating. One cause of this could be water bleeding into concrete during finishing that can elicit high water-ratio in concrete and weaken the concrete-surface.
Flaking and Peeling
The freeze-thaw process that takes place with finished concrete oftentimes leads to flaking and peeling. Certain factors which can contribute to this issue include failure to use air-entrained concrete that is required to prevent the adverse process.
Fine Cracks on Concrete-Surface
The surface-layer of concrete can in certain cases begin forming a network of fine cracks. The problem is oftentimes occasioned if a rapid procedure was used for drying or the concrete was not cured adequately.
Expansion and concrete of concrete without providing room for alleviating the stress created is the most common reason which causes cracks on concrete. It could be due to improper jointing, shrinkage as well as settlement, while freeze-thaw action or external restraint like flooring are possible other contributors to this kind of problem.
Cracking owing to shrinkage is yet another common issue that affects concrete. It can happen if rapid evaporation occurs on the surface before concrete sets. Engaging professional Bathurst Builders can for example prevent this kind of outcome when undertaking construction activities.
The strength of concrete can be reduced if improper procedures for casting, handling and curing are employed. High air content, excessive amount of water or error in manufacturing concrete might also cause this problem.
De-lamination explains a situation in which separation takes place between the top and bottom slabs that could be occasioned by a think air or water layer. This issue can arise if air entrained concrete applied for hard finishes can seal the surface while bleed-water is still present and thus overwork the surface. Making use of a polyethylene vapor barrier can also lead to this problem.
Use of calcium chloride for expediting set times, changing material sources or mix proportions and uneven curing are among the most common causes of discolored concrete.
Distortion of the flat surfaces into curved shapes is what takes place when curling of concrete occurs. Oftentimes, this arises owing to temperature-differentials in content of moisture in-between the top and bottom slabs.
Spotty or Uneven Setting of Concrete
Failing to perform thorough concrete-mixes is the most common reason that makes concrete spotty or uneven. Use of certain super-plasticizers with normal setting and retarding mixtures are the other possible causes.
