Description
Mohamed Ahmed and colleagues test steel slag concrete as a strengthening layer for reinforced concrete flat slabs. Their 2026 study replaces all natural aggregate with blast furnace slag in the overlay material.
Five slabs were loaded statically and compared against fibre polymer, steel-fibre concrete, and high-performance concrete strengthening methods. The slag overlay raised ultimate load by about thirty percent and first-crack load by about sixteen percent. Deflection at failure fell by over half versus the unstrengthened slab. A validated computer model then explored twenty-two configurations varying overlay thickness, slab proportions, and reinforcement corrosion. The authors recommend an overlay of twenty to thirty percent of slab thickness as optimal.
