Andritz Brasil completes largest concreting work for Klabin's Puma II project in Brazil
November 22, 2019
BRAZIL (News release) -- Andritz Brasil Ltda. successfully completed concreting work for the base of the Line 5 debarking drum, which is part of the wood preparation equipment (Andritz scope) being supplied in partnership with Afonso França.
This is the largest concreting volume in Klabin's Puma II project and required approximately 750 m3 of concrete, which corresponds approximately to the concrete volume needed for a 14-storey building.
While this work was performed in two stages in the first Puma project, this time concreting was completed in a single step. The process is highly complex because the concrete must be kept at a temperature between 18 and 22°C for this kind of concreting in order to prevent any cracking in the base. About 70 tons of ice mixed with the concrete were used to maintain this temperature.
