Durability in aggressive environments.
The profile describes an in-house study at the Mussafah R&D Center in collaboration with McGill University, Montréal. The work investigated chemical exposure of concrete specimens containing Portland cement and varying proportions of GGBS, fly ash and micro silica.
Exposure solutions included sodium chloride, sodium sulphate, calcium hydroxide and seawater. The assessment considered chemical profiling, ultrasonic pulse velocity, surface resistivity and physical observations.
What the study explored
The profile reports more severe deterioration in the tested 100% Portland-cement specimens than in the tested blended-cementitious specimens. The findings support further investigation of material combinations for exposure-specific durability.
These observations relate to the study’s samples and exposure conditions. They are not a universal durability guarantee or a substitute for a project-specific mix design.
