Concrete chipping, also known as concrete cancer. Like the dreaded C word in humans, concrete cancer corrodes walls from the inside. It is the rupture of the concrete surface due to the oxidation of steel reinforcement inside a concrete slab. Once steel starts to rust, it expands and deforms.

Expanding steel can often break or blow concrete, causing pieces to fall off the concrete slab. This is known as “chipping”. Naturally, this increases the exposure of steel and the problem worsens. While the problem may initially seem like an aesthetic or cosmetic concern, the reality is more sinister.

Steel bars resist tensile forces in concrete, and the cross-sectional area of each reinforcing bar works hard to withstand the load it has to withstand. As the steel rusts, the effective cross sectional area of the bar is reduced, until eventually there is not enough steel left intact to withstand the forces. At that point, the slab (or beam, column or ladder, etc.) is now severely weakened and runs the risk of suddenly failing or collapsing. However, if the concrete is not prepared properly and the steel is not protected from water, a problem known as concrete cancer occurs.

Concrete cancer, also called alkali-silica reaction (ASR), is a serious problem that can damage or destroy structures made of concrete. The concrete used in buildings is reinforced with steel and iron bars or meshes. When exposed to air and water (for example, through leaks of a higher level), a weak carbonic acid begins to form and the bars begin to corrode. Concrete is a porous material and can easily absorb surrounding elements, including this corrosive acid.

Once corrosion begins, the steel expands and causes the surrounding concrete to crack, which is known as chipping. Chipping can trigger a vicious cycle by further exposing steel to the elements and accelerating the level of corrosion. The impact on the building leads to a tragic compromise of structural integrity. Flat concrete roofs are an example of a building structure that is particularly vulnerable to leakage and water-driven concrete cancer if not adequately waterproofed.

If your concrete is already set, you may consider installing a sheet of waterproof membrane on the surface of the concrete. A structural engineer can accurately diagnose cancer, but he or she may be able to determine if your building has been affected by the problem by looking for some telltale signs. If you need help repairing, removing or installing new concrete, compare quotes for concrete mixers near you. Sometimes experts may recommend the use of additional reinforcing steel anodes before applying new concrete, or steel can be replaced in severe cases.

This expansion of the rusty steel rebar will cause the concrete to stain, crack, and eventually, over time, large pieces may fall out. If you suspect that your building has specific cancer in any form, it is important that you treat it as soon as possible, otherwise the problem will only get worse and more difficult or expensive to fix. Concrete is one of the most common building materials in use today, and you are likely to find it in almost any house or building. Concrete is often reinforced with steel rods, wires and bars to increase its strength for civil structures.

When it comes to concrete repairs, be sure to seek a professional opinion from a reputable company such as Freyssinet. This minimizes the risk of future water damage and prevents harsh chemicals that contaminate concrete from entering through the pores. This is because defective concrete is more likely to be filled with holes and cracks that allow moisture to seep into the metal. This blog explains what specific cancer is, its causes and signs of specific cancer with examples of when it has caused damage and how to prevent it.

Repairing heavily damaged concrete can cost thousands of dollars, so it may not be profitable compared to replacing it. .
