What causes concrete damage in a storage tank?

Recurrent damage: wet areas, cracks and heavy concrete spalling in the lower parts of the beams. Heavy concrete spalling was also found in many storage tank columns, especially near the foundations accompanied by large damp spots due to rising damp from the ground, which accelerates concrete degradation.

What causes heavy concrete spalling in storage tank columns?

Heavy concrete spalling was also found in many storage tank columns, especially near the foundations accompanied by large damp spots due to rising damp from the ground, which accelerates concrete degradation. Fig. 14 shows an image and scheme of the cracks (A) damp areas, and heavy concrete spalling (B) in a column of ST16. Fig. 14.

Do storage tanks with the most serious spalling have a thin layer of concrete?

During the survey it was verified that the storage tanks with the most serious spalling had only a thin layer of concrete cover (less than 2 cm). In addition, the poor quality of the concrete is connected to the presence of microcracks and high porosity of the material.

How does weather affect reinforced concrete (RC) structures?

1. Introduction Exposure to aggressive environmental agents, aging and extreme weather events can seriously harm Reinforced Concrete (R.C.) structures and affect their performance .

How to improve the service life of concrete structures in Valencia?

The following interventions can be recommended to improve the service life of the structures in the Valencia region. Direct application of a corrosion inhibitor onto the reinforcement bars. Cleaning and moistening the support surface and concrete restoration by premixed mortars prepared on site to increase the thickness of the concrete cover.
