Consider these tips to prevent concrete degradation and avoid spending thousands of dollars on repair. Listed below are some of the best practices for concrete maintenance.
Prevention of concrete degradation
Despite its durability, concrete is subject to deterioration due to various factors, such as exposure to harsh weather, reactions with common elements, or poor construction. In this article, we will discuss the factors contributing to concrete structure degradation. Among these factors, we will discuss rust, a byproduct of the electrochemical process. Rust inside the concrete can cause cracking and deterioration.
Water is the most destructive agent to concrete since it participates in many chemical reactions as a reagent. Without water, harmful reactions cannot proceed, and they are slow. Therefore, preventing water infiltration is essential for the durability of concrete structures. However, this method does not always work. The physical and chemical processes are closely linked. Water infiltration accelerates the formation of harmful swelling chemical reactions, which is why preventing cracks and moisture infiltration is critical.
The prevention level depends on the concrete type and its exposure to various elements. If you use concrete in a humid environment, you must be particularly careful about the concrete’s climatic conditions and temperature. The more moisture and water the concrete receives, the higher the temperature will be at the core. The recommended precautions are based on these factors. This way, you’ll be more likely to prevent concrete degradation and ensure that your assets remain in top condition.
One of the most important steps in preventing concrete degradation is limiting its exposure to water with sulfate content. The sulfate in water can cause significant changes in the cement paste, leading to a weaker binder. As a result, the resulting crack networks indicate a sulfate attack on concrete. To avoid these problems, you should try to limit the water content in your concrete and the ratio of water to cement.
In addition to the above steps, you should also avoid using concrete that contains too much water. This may result in shrinking cracks. The concrete loses moisture during the hydration process, leaving larger pores un-saturated. Furthermore, it will not reach its strength potential. In addition, excessive water will result in a loss of structural capacity and a higher chance of cracking. These factors are just some of the factors that cause concrete to degrade.
Physical and chemical forces affecting concrete degradation
The degrading process of concrete in the marine environment combines physical, chemical, and mechanical forces. Marine concrete is divided into three zones subject to different attack types. The Tidal Zone is the most aggressive area and is subject to alternate wetting and drying cycles that accelerate chemical action on concrete and reinforcement steel. These conditions can cause several problems, from cracks to detaching and tearing.
The temperature and humidity of the environment are two of the most critical factors affecting concrete’s durability. Concrete’s alkalinity decreases when high temperatures, causing it to shrink and deteriorate. This deterioration can be prevented by using nonreactive aggregates or using low-alkali cement. Also, proper detailing and isolation joints can help reduce the effect of temperature variations on concrete’s durability.
The carbonation of concrete occurs when atmospheric carbon dioxide diffuses into the concrete from the surrounding air. The carbon dioxide reacts with calcium hydroxide in the concrete pore water and lowers its pH to 13.5 to 8.5. As the pH decreases, the solubility of iron oxides increases, and the carbon steel on the surface begins to oxidize. The concrete is then exposed to the air and becomes cracked and spalled.
Combined with the chemical forces affecting concrete, dissolved carbon dioxide has a very aggressive effect on concrete. During this process, dissolved carbon dioxide reacts with calcium ions to lower its pH and causes pitting corrosion. These chemical reactions are further accelerated by water infiltration and the formation of cracks. The two processes are intimately related and interact to cause degradation. For instance, water infiltration accelerates the formation of harmful ions and gases that cause concrete deterioration.
Among the chemical forces that affect concrete, sulfate attack is the most significant. When sulfates react with cement, it attacks hydrated calcium aluminates, causing calcium sulphoaluminate to form. The resulting calcium sulphoaluminate has 227% of the original aluminates. The calcium sulphoaluminate increases the volume of concrete, causing it to expand and develop cracks.
Methods of extending the life of concrete surfaces
While concrete will eventually peel and crack, there are practical methods for extending its life and preventing issues. Many structures have concrete surfaces. Avoiding moisture and other elements is important, as these factors can cause the concrete to erode. Clean concrete regularly. Use a high-powered hose or pressure washer to remove dirt and debris. You can also use a concrete floor scrubber to remove residue. These steps can extend the life of the concrete and save you money.
Protect the surface from harsh chemicals, environmental hazards, and abrasive foot traffic. Water stains concrete and can cause cracks. It can also make concrete slippery. Make sure the concrete surface has a slope to drain water quickly. Antiquing is another option to protect concrete surfaces. This technique involves a layering of colored compounds to give it a weathered look. The methods recommended by the American Concrete Institute and the American National Standards Institute (ANSI) are based on scientific research.
In the past few years, successful repairs to historic concrete structures have been made. However, the success rate of concrete repair is still too low, with less than 50 percent of repairs performing satisfactorily. Fortunately, today’s methods for extending the life of concrete surfaces are more effective than ever. Ultimately, concrete preservation is an ongoing process. As concrete repair technologies improve, more concrete structures can be preserved for many years.
Cost of repairs
The cost of repairs for concrete maintenance is important to assess the structure’s condition. While it is less expensive than replacement, repair may be more complex for load-bearing concrete structures. The cost of repairs can also vary greatly depending on the location, size, and materials used. A probabilistic method can be more appropriate for concrete repairs than a single-element approach, as it considers engineering uncertainties, continuous repair costs, and other variables.
The cost of repairs for concrete maintenance varies according to the location, type, and severity of the damage. In general, the concrete repair will cost anywhere from $500 to $1,000, although the exact cost will vary depending on the extent of the damage. While this is a reasonable range, it’s important to consider the money needed to fix the problem. Concrete repair contractors can assess any damage to the structure and repair it accordingly, avoiding costly mistakes.
Although concrete is one of the most durable construction materials, it is susceptible to cracking and crumbling over time if not appropriately maintained. Although homeowners can repair minor cracks, larger repairs need professional assistance. Before major repairs, a reliable concrete contractor will complete three preliminary steps. These preliminary steps add to the cost of repairs but ensure that the concrete will last a long time. And this is important to your home’s foundation, as cracked concrete can affect the strength of the structure of a home.
A professional repair can range from $4 to $15 per square foot. In some cases, the cost will be lower, but the final cost depends on the severity of the damage. In general, a 24-foot-by-24-foot area can cost upwards of $1,150. Minor repairs are often performed by patching, which involves mixing a concrete compound to fill the cracks and form strong bonds with the concrete surface. This mixture contains cement, polymers, and additives that help concrete bond to the surface.
