Advances in concrete materials for sewer systems affected by microbial induced concrete corrosion: A review

Microbial induced acid corrosion from a field perspective - Advances in process understanding and construction material development

“…Gained in depth knowledge of the physicochemical construction material characteristics and their impact regarding biofilm adhesion, development and structure form the basis for continuative development of suitable materials. In this context, geopolymer based construction materials exhibit great potential as an alternative, highly stable construction material for aggressive sewer systems [6].…”

“…Accordingly, an extensive field campaign is presented in which innovative geopolymer concretes (GPC) were tested in respect to their overall performance in MICC environments, compared to conventional ordinary Portland and CAC cement based concrete materials. Due to their geopolymer characteristics, they potentially combine positive properties of vitreous ceramics (acid, permeability and abrasion resistance) with advanced performance of concrete pipes (low temperature molding, no dig repair, any pipe diameter possible), while overcoming their individual specific limitations at the same time (Ceramic: brittle, small diameters, dig renewal, higher cost; OPC-based Concrete: low durability) [6]. In contrast to existing concepts for concrete durability based on neutralisation by an inevitable dissolution of concrete, geopolymers are acid resistant [7], and are expected to provide a much longer-lasting and thus highly stable barrier against MICC, while acting as an implicit pipe protection.…”

Improvement of functional performance of concrete in livestock buildings through the use of complex admixtures

“…An option to overcome this problem may consist in introduction into the concrete used for flooring in the livestock buildings such admixtures that would protect it against biological damage and animals against pathogenic microflora [15,16].…”

Analysis of Effect of Protective Coatings on the Rate of Corrosion in Reinforced Concrete Sewers Microscopic Study

“…Coating of sample BSample A was first placed in sewage sample "Y" for 30 days and after 30 days of chemical attack, it was washed and dried. A single layer of coating was applied in the same manner as for sample B(Mobin et al 2012;Grengg et al 2018). …”

“…The economy of the sewerage system adversely affected by the service life of RC sewers(O 'connell et al, 2010). Walsh, 1993) , have good chemical and abrasion resistance, exceptional bonding on concrete surface thus contending the corrosion of sewers(Grengg et al 2018). Current research focused on the durability and analysis of polyurethane coating against MIC using…”
