Protection of interrupted concrete structure to prevent degradation: a case study

Protection of interrupted concrete structure to prevent degradation: a case study In interrupted concrete structures is fundamentally relevant to adopt protective measures, which purpose is minimizing degradation to ensure project life cycle, in addition to subserve a future construction resumption. In this context, this paper presents a case study of prestressed and reinforced concrete structures, located in Foz do Iguaçu, Paraná, Brazil, whose execution was interrupted in 2014. At that time, the constructions were in superstructure execution phase. With an area of 155,000 m2 and investment of $ 31 million, the constructions belong to Brazilian Federal Government and are destined to Federal University of Latin-American Integration (Unila) installations. It was observed that performed protection works were mainly related to exposed reinforcement protection, waterproof and protection of structures in contact with soil, and drainage services execution. The protection costs were approximately 1.4% of investment value, following the Sitter’s “Law of fives". Thus, the technical and economic importance of protective measures adoption in concrete structures that had their works interrupted is noted, so that the case study serves as a model for other buildings in same situation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Building Pathology and Rehabilitation Springer Journals

Abstract

In interrupted concrete structures is fundamentally relevant to adopt protective measures, which purpose is minimizing degradation to ensure project life cycle, in addition to subserve a future construction resumption. In this context, this paper presents a case study of prestressed and reinforced concrete structures, located in Foz do Iguaçu, Paraná, Brazil, whose execution was interrupted in 2014. At that time, the constructions were in superstructure execution phase. With an area of 155,000 m2 and investment of $ 31 million, the constructions belong to Brazilian Federal Government and are destined to Federal University of Latin-American Integration (Unila) installations. It was observed that performed protection works were mainly related to exposed reinforcement protection, waterproof and protection of structures in contact with soil, and drainage services execution. The protection costs were approximately 1.4% of investment value, following the Sitter’s “Law of fives". Thus, the technical and economic importance of protective measures adoption in concrete structures that had their works interrupted is noted, so that the case study serves as a model for other buildings in same situation.
