The largest “core locs ®” in the world were built in the Azores, more precisely in Porto in the city of Praia da Vitória on Terceira Island and CIMPOR actively participated in the work, supplying, through its associate CIMENTAÇOR, the cement for its manufacture. They are actually the largest pieces of their kind ever produced, each with a volume of 13.3 m3 and a mass of approximately 33 tonnes.
The port of Praia da Vitória is the largest port on Terceira Island and represents a fundamental infrastructure for the entry and exit of raw materials and goods, namely those that have directly to do with the operation of the US military located in Lajes.
The damages caused by the storms of 2001 and 2005 required emergency repairs in which BAIRD, contracted by the US Government, SETH as general contractor and SOMAGUE-EDIÇOR as manufacturers of the “core-locs”, intervened as a designer.
In the first phase, which took place in 2003, 322 elements were manufactured, while in the second, which was carried out between January and June 2006, the number was 285. The entire protection of the jetty was completed with the manufacture in 2008 of another 353 units.
During the second phase of the work there was a very serious reformulation of the project, which raised the tensile strength of concrete to flexion from 3.5 MPa to 5.0 MPa and also forced the introduction of synthetic fibers.
In the first phase of the work, the CEM II / BM (VL) 32.5 N produced at the Sines mill was used and made available by CIMENTAÇOR in Terceira while in the second the CEM II / AL 42.5 R from the Alhandra plant was used to respond more effectively to increased mechanical demands.
This project also had the collaboration of APEB who, in the person of Engº Luís Saraiva, studied the composition of the concrete and closely monitored the execution of these pieces.
