Concrete is a widely used construction material due to its durability, strength, and low cost. However, it is not immune to deterioration, and one of the most common problems that can occur is concrete cancer. Concrete cancer is a term used to describe the deterioration of concrete caused by the corrosion of steel reinforcement within the structure. This type of damage can be a serious problem, potentially causing structural instability and compromising the safety of the building.
The Australian Concrete Repair Association (ACRA) is an organization dedicated to promoting the best practices in concrete repair and remediation. According to ACRA, concrete cancer is measured by the severity of the damage and the extent of the corrosion. The severity of the damage is evaluated based on the size and depth of the cracks and the extent of the spalling or delamination. The extent of the corrosion is determined by measuring the loss of cross-sectional area of the steel reinforcement.
It is important to consider all aspects in the cost of a remediation project for concrete cancer. ACRA recommends that the cost of a remediation project should be evaluated based on the severity and extent of the damage, the accessibility of the affected area, and the difficulty of the repair. The cost of the remediation should also include any necessary testing and monitoring, as well as any potential disruption to the occupants of the building.
When it comes to remediation of concrete cancer, ACRA provides specific technical advice and details on their website. They emphasize the importance of proper surface preparation and treatment of the affected area before applying any repair materials. This includes cleaning the surface thoroughly and removing all loose and deteriorated concrete. The steel reinforcement should also be treated to prevent further corrosion before any repair materials are applied.
ACRA also recommends the use of high-quality repair materials that are specifically designed for the type of damage being repaired. The repair materials should be applied according to the manufacturer's instructions and any necessary curing times should be observed. ACRA also recommends that the repair work should be carried out by qualified and experienced professionals who are familiar with the best practices in concrete repair and remediation.
In conclusion, concrete cancer is a serious problem that can compromise the safety of a building. Measuring the severity and extent of the damage is important in determining the cost of a remediation project. It is also important to consider all aspects of the project, including testing and monitoring, accessibility, and potential disruption to the occupants of the building. Following the technical advice and details provided by ACRA on their website is crucial in ensuring that the repair work is carried out properly and effectively.
