How to Avoid The Deterioration of Concrete
Concrete dates back to 3000 BC when the Egyptians used an early form of the construction of the pyramids. Due to technological advances and a diversified market, the concrete has come a long way since the first formula. However, there is still a relatively fragile material. Usually made of water, Portland cement and aggregates (sand or rock), is the finished product able to say well under pressure, but remains susceptible to wear. How to avoid the deterioration of concrete is useful, but if the concrete is already in ruins, you need to know what is causing the deterioration of the order of the process.
The water cement in concrete can contribute significantly to resist the survival or the ability to break down. Although it does not corrode, as some metals, is still susceptible to corrosion due to chemical and physical effects of porosity.
Concrete can be chemically weakened because it is porous. When items are allowed in the concrete, corrosion is the result. Corrosion can be distributed reinforcements used – re-bar in most cases – which will lead to rust, decay and violence reduction. The acids can also contribute to a deterioration, and that can actually dissolve the cement mix in concrete. Naturally, this will result in reduced structural reliability.
Efflorescence is another common problem caused by water-soluble salts. These salts are found in surface water has been poured into the concrete. As the water evaporates, the salt residue on the surface as a white powder remained.
Allows the use of fibers in the mixture to strengthen the concrete filler wire, oxidation and corrosion. The fibers also minimize cracking, while the mesh is held together only existing cracks. A concrete hardener and compressors can help to overcome the penetration of acid into the concrete. A concrete hardener will also be protected against the ingress of salt and water, leading to efflorescence or white with dust.
Because concrete is porous, which is sensitive to damage by freezing and thawing. Since water temperature is in the concrete and reduce and freeze its expansion, putting pressure on the bottom. This pressure can be greater than the strength of the concrete, causing cracks and flaking.
To avoid this, the air entraining additives used in the original concrete mix. Air entraining agents to create microscopic bubbles in the concrete. When the water freezes and expands, it will go on air bubbles do the concrete, preventing damage. A concrete hardener can be protected against the ingress of water and other freezing and thawing.
Although concrete will also be under pressure, heavy loads and constant pressure to wear down, causing a loss of strength, abrasion, tears and more. Prevent this type of error may be physically impossible, but minimizes the occurrence of continuous use is an option. Diamond wheel blasting or can even be made from abrasion and impacts on concrete maintenance concrete sealers to provide a layer of protection against scratches the surface. The cause of the reduction will help prevent further deterioration of the concrete solutions and keep looking new and fresh.
