UNIQUE TECHNOLOGY FOR STOPPING BIOGENIC CORROSION

A WHOLE RANGE OF APPLICATIONS: FROM PIPES TO SEWAGE SYSTEMS

For more than fifty years, calcium aluminate concrete and mortar has been used for a wide range of applications: protection of ductile metal, steel or concrete ducts in waste water systems, or new construction or renovation of sewage system infrastructure (drains, treatment plants, pumping stations, collectors, etc.).

Pipes made from ductile metals and from steel
A number of global ductile metal pipe manufacturers have chosen CALCOAT® RG mortar to line the inside of their wastewater ducts. The product is also used in steel pipe protection.
The European quality standard EN 598 lists aluminous cement mortar as the material most suited to lining the inside of ductile metal duct pipes in wastewater treatment systems. The application of this mortar by centrifugal or rotating distribution head systems results in a smooth and compact layer which is resistant to abrasion and biogenic corrosion.

Concrete pipes _ Calcium aluminate concrete and mortar produced by Kerneos have been successfully used since the 1950s for centrifuged concrete duct pipes designed for use in harsh environments, both as mass concrete and surface coating. The mortar formulated with calcium aluminates may also be used for the protection of duct pipes manufactured via the Rocla process.
Kerneos boasts a long list of proven experience in sewage systems subject to severe biogenic corrosion and abrasion around the world: North America, Malaysia, Singapore, Taiwan, South Africa, Egypt, Morocco, Sweden, etc.

Construction and renovation of sewage system infrastructure
Kerneos has developed a unique range of cements and mortars for protecting and renovating the infrastructure of sewage systems (collectors, wastewater treatment plants, pumping stations, etc.)
Beyond their intrinsic properties of abrasion and biogenic corrosion resistance, calcium aluminates offer a simple and uncomplicated application procedure with a whole range of possible applications. They may therefore be used in traditional applications such as dry or wet spraying, or else with rotating distributor heads. Calcium aluminate concrete may also be used in the manufacture of prefabricated structures such as inspection manholes. Calcium aluminate is generally considered as the best solution for renovation work, offering advantages over polymer systems which are much more difficult to work with.

A COMPLETE RANGE OF PRODUCTS

In 1908 Kerneos invented CIMENT FONDU®, the first industrial calcium aluminate, and today it offers a complete and unique line of specialized cements and mortars for coating duct pipes and sewage system infrastructure:

• CIMENT FONDU® is a hydraulic binder containing approximately 40% alumina with a dark grey colouring. It has more than fifty years of proven experience in sewage system protection worldwide.

• CALCOAT® RG is a hydraulic binder specially developed for duct pipe surface coating which contains approximately 50% alumina. It features simple application procedures and robust quality for a wide range of climates, as well as light colouring to facilitate video monitoring of the sewage system.

• SEWPERCOAT® is a line of ready-to-use mortars whose formulation includes aluminous cement and aluminous synthetic aggregates which provide it with exceptional resistance to corrosion and abrasion. The SEWPERCOAT® line of products offers different formulas which are specially developed for each application method, whether dry or wet spraying, industrial centrifugation procedures or traditional concrete pouring.
