Strand spacers are provided in the anchor bond zone to separate the
strand and provide for the minimum required grout cover around each
strand for corrosion protection and bond strength development. The
strand spacers are normally located 30-60 cm above the bottom of the
anchor and at the top of the bond zone. The intermediate strand spacers
are typically placed at a distance of 150-300 cm. center to center along
the bond zone between the top and bottom spacer
