USO DE CONCHAS DE MARISCOS COMO AGREGADOS NA CONSTRUÇÃO CIVIL: Relato de experiência com pescadores no Litoral Norte de Pernambuco

Abstract

This research refers to the experience report that was based on a research project carried out by the EcoSoluções group of IFPE/Campus Recife registered with the CNPq, substantiated by scientific initiation (PIBIC) and extension (PIBEX) of courses, technician in Buildings and higher. Of Civil Engineering. The objective of this work was “to report the experience with fishermen from the North coast of Pernambuco in the viable use of oyster and shellfish shells as aggregates for civil construction”. Therefore, based on the need to minimize the negative environmental impacts caused by mariculture activities on the northern coast of Pernambuco, research was carried out, and the extension tried to return the knowledge concerning the use of oyster and shellfish shell residues to the fishing community. In cementitious composites: mortars; concrete without structural purposes; blocks for sealing and paving masonry. It was verified in the production of these new materials, an average cost reduction, in relation to conventional materials, of more than 50%. The practice exercised in the extension, which considered informing fishermen in the studied region of the research results, was conducted along the path guided by informal education (GOHN, 2013), supported by the model of eloquence adequate to the understanding of the interlocutor, as well as highlighting the importance of if conditions were built so that professional fishermencould pass them on to each other, in the most adequate and easy way possible. Mortars are basically for flooring (cemented flooring) and for lifting masonry; concrete for subfloor, internal flooring, sidewalks, etc.; manually pressed blocks can be used in sealing masonry and internal and external paving without structural purposes. Nevertheless, this research conglomerate generated several publications of scientific articles in congress and journal, as well as the edition of a book. Finally, it is possible to identify in this work, aspects in the exercise that underlies the formation law of Federal Institutes (Law 11,892/2008), such as: promoting the production, development and transfer of social technologies, notably those aimed at preservation the environment; carry out applied research, stimulating the development of technical and technological solutions, extending their benefits to the community.
