Improving concrete durability

Silage silos –

→ 1 Concrete damage at a precast concrete element of a silage silo after a service life of two years

→ 2 Installation of concrete specimens in a silage silo

Assessments of the corrosion resistance of building materials are currently focusing on such fields of application that are associated with biogenic sulphuric acid corrosion (BSA). In particular, damages occurring at wastewater treatment plants attract more and more public attention, especially in times of increasing maintenance and repair costs for infrastructure networks. They are also stimulating discussions on showing ways for an improvement of the chemical resistance of construction materials.

Today, biogas is understood as a renewable and sustainable energy source being produced at many...
