We place ducts in slab, pour concrete, stress strands to 140 kN each after 28 days—compresses concrete, allows 10m span vs 5m RCC.
Mono-strand coated with grease, HDPE sheath—strand slides freely, easy to replace, used in transfer beams.
Cast-in dead end barrel, live end with 3-piece wedge, lock after stressing—holds 186 kN permanently, no slip.
500 kN mono-jack with 600mm stroke, digital gauge, stresses 4 strands simultaneously—elongation within 5% of calculated.
Cement grout with expander, 0.35 w/c, pumped from one end—protects strand from corrosion, bonds to concrete.
