New Administrative Capital · June 2023The challenge
A supertall structure is, before anything else, a concrete logistics problem: high-strength mixes that must stay pumpable to height, pour windows planned against Cairo’s heat, and no tolerance on strength compliance across the structural programme of Egypt’s new Capital Business District centrepiece.
The CASTECH system
CASTECH supplied concrete admixtures and a range of specialty construction chemicals for the project: PCE-based superplasticizer systems tuned in plant trials for slump retention and pumpability in a hot, arid climate, with dosing support alongside the ready-mix producer during the pours.
The outcome
High-strength, highly pumpable concrete delivered consistently for the tallest tower in Africa — the kind of reference that says more than a datasheet.
