- Reinforced concretes are usually attacked by water and rusted. This is due to, a. Low density cements or high porosity that allow water to reach the steel b. The expansion of the rust as it has higher volume than steel push the cement cover and break it c. All the options d. None of the options e. The cover thickness is too small (the steel is too close to the end of the concrete block)Which of the following directly causes sulfate attack in concrete? CH Delayed ettringite formation CO2 C-S-HListen Concrete is required for the construction of an agricultural dairy barn floor slab in Central Alberta.
