Performance of CCA treated Eucalyptus round ties

IRG/WP 3342

V J Carlos, F R Niederauer, J P P Wehr

After 5.5 years of field exposure in the south of Brazil round Eucalyptus ties treated with CCA type A Oxide (OSMOSE K-33-A) preservative with retentions from 12 to 14 kg/m³ (0.75 to 0.873 PCF) (active ingredient basis) are performing very well. No decay or insect attack was observed in the 100 ties in test in real conditions of use; 10% of ties show incipient checking (what is a natural trend of Eucalyptus ties) and 3% show weaking of the nails.
