Concrete Spalling / Concrete Cancer

 

 

Concrete spalling or as its often refer to as concrete cancer is caused when steel reinforcement within a concrete slab begins rusting. When steel rusts it expands approximately 5 times its original size causing concrete cracking and flaking.
Once this damage occurs generally more water can enter the affected area, speeding up the process.
Generally the exact cause concrete cancer often depends on the individual circumstances of each case.
These include the steel being too close to the surface allowing water to react with it, poor quality steel, incompatible metals used close to each other causing a reaction, and damage to concrete allowing water to enter the slab and come into contact with the steel.

One of the biggest cause of concrete spalling is where Magnasite has been used as a floor topping. Magnasite was used extensively in the 70,s as a floor topping but has no become one of the biggest causes of Concrete Cancer
