Post-Tensioning Silos with DYWIDAG Strand Tendons: The Al Arish Cement Plant in Egypt
Recently, a cement plant was extensively expanded in the northeast of the Sinai Peninsula near the coastal town of Al Arish.
2 raw meal silos, 2 clinker silos and 4 cement silos with a production capacity of 11,000t of cement per day were built in the first project phase between 2009 and 2010. The Egyptian DSI licensee MISR DYWIDAG participated in the construction of 6 of those silos.
During the second expansion phase in 2015, 2 raw meal silos, 2 clinker silos and 4 cement silos were built that will increase production capacity by 11,500t of cement per day.
MISR DYWIDAG carried out the posttensioning work on all silos. One raw meal silo, one clinker silo and the 4 cement silos were built together with the contractor Gama for Trading & Contracting S. A. E. The other raw meal silo and the second clinker silo were built in co-operation with the contractor SIAC.
The silos were built using the slipform method. Work was carried out in 2 shifts, with approximately 1m concreted per shift, which roughly equals construction progress of 2m per day.
For post-tensioning the silos, MISR DYWIDAG supplied and installed Type 7-0.60 " DYWIDAG Strand Tendons with a total weight of 435t and 2,840 Type SD Plate Anchorages.
Since MISR DYWIDAG simultaneously worked on 4 silos, a total of 40 technicians and 4 supervisors was on site. The fact that the silos had to be completed with two different contractors within a very limited timeframe posed a special challenge.
