A presente obra, intitulada Controlo de qualidade do betão: estudo do fenómeno da segregação na construção urbana, analisa o fenómeno da segregação observado no âmbito do projeto de construção de 1 300 habitações coletivas na localidade de OLEMBE, nos Camarões. O projeto de Olembe insere-se no vasto programa de construção de 10 000 habitações sociais lançado pelo Governo dos Camarões. Este trabalho foi iniciado na sequência de inúmeros danos nas infraestruturas, tais como o desabamento de edifÃcios e outras obras, registados nos últimos anos no paÃs. Foram então observadas in situ deformações superficiais, consistindo principalmente em ninhos de cascalho mal revestidos e armaduras corroÃdas. A heterogeneidade do betão aqui em causa seria inerente à multiplicidade de manipulações. Tal poderia originar defeitos de porosidade que afetam a resistência à compressão. A durabilidade das construções poderia, assim, ficar totalmente comprometida. Este estudo pretende, portanto, ser uma ferramenta de sensibilização e de aprofundamento dos conhecimentos dos diferentes intervenientes sobre este fenómeno, demasiado frequentemente observado e negligenciado na construção urbana.
