ON THE COVER Hydrogen sulfide (H2S) gas buildups within wastewater networks are the main cause of accelerated biogenic corrosion in concrete structures. Unless countered, H2S will significantly shorten the life of infrastructure assets – but there’s a proven solution using specialty calcium aluminate cements and aggregate products developed by French multinational Imerys, operating locally as Kerneos Southern Africa.
