Post-tensioning floor slab solutions are often employed to reduce floor slab thicknesses and reinforcement and achieve significant embodied carbon reduction. We promote the use of low carbon reinforcement and post-tensioning strand materials based on 97% recycled steel, secondary EAF production with up to 100% clean/renewable energy. For tall buildings, the adoption of thinner PT floor slabs can also result in reduced loads on the foundation system, leading to further material and embodied carbon reductions.

"Our PT slab solutions can reduce embodied carbon by up to 30% compared with the equivalent RC slab without over-specification of globally constrained cement replacement materials such as GGBS." Alessia Piras, Director
