Increasing the chemical resistance of concrete

Opportunities arising from the use of innovative binders

Concrete structures are subjected to a wide variety of exposures. In pertinent codes and standards, these exposures are allocated to typical use scenarios. In the case of concrete corrosion triggered by chemical attack (i.e. exposure classes XA 1 to XA 3), such as by exposure to natural soil, groundwater or seawater as well as industrial wastewater and agricultural fluids, comprehensive research has been conducted in the past few years because of the increasingly demanding requirements for structures, primarily in pipeline and sewer construction but also for the installation of silos, tanks...
