The performance of the vertical sealing elements is determined by the level of protection to which they are subjected. Construction processes are changing and cementitious coatings are increasingly taking place among current construction options. On the other hand, the weather has its increasingly aggressive and more evident incidence. The performance standard sets the guidelines for seal manufacturers to meet expected quality standards. Given the above comes the importance of evaluating the best particle size composition to obtain the ideal mortar manufacture. Water transport mechanisms are the actors in this permeability process with the effective participation of diffusion and capillarity. The present study proposes observations about the water absorption of cementitious coatings manufactured with three sand granulometry (fine aggregate). The mixture containing the fine sand obtained the lowest absorption while the mixture with the highest grain size presented the highest absorption and the highest flow rates.

Waste reuse is considered an excellent alternative for sustainable development. For the World Commission on Environment and Development in Our Common Future, sustainability is "one that meets the needs of the present without compromising the ability of future generations to meet their needs." One way to provide a sustainable solution for glass would be the reuse of glass waste in the production of concrete. Glass residues when suitably crushed and sieved, to assume appropriate granulometry, may exhibit characteristics similar to natural aggregates. The use of glass waste when used in concrete manufacturing reduces production costs. The main objective of the research was to replace, as much as possible, in percentage, the quantity of sand and gravel aggregates by glass waste with the same granulometry, as a way to reduce costs, reduce the use of raw materials and reduce the quantity of wastes that were inadequately disposed of in landfills. Samples of glass waste were collected in the construction industry itself, in works and glassware companies that work with cutting and delivery of the product. Comparisons were made between concretes produced with natural and concrete aggregates produced with the substitution of 20%, 30%, 40% and 50% of the fine aggregate, all of which glass was used as a substitute. The comparative analyzes were the mechanical properties of compression strength and diametral compression traction at 7, 14, 21, 28 and 90 days.

A variação do nível das águas na região amazônica influencia as atividades comunitárias, sendo necessárias adaptações para o modo de vida amazônida. Assim podemos ressaltar a interferência nas atividades escolares dos ribeirinhos. Tendo a formação escolar como única porta para o progresso, o ribeirinho procura adaptar-se com o meio. Com a variação dos níveis das águas, a estrutura da escola é afetada drasticamente provocando interrupções no calendário letivo. Para mitigar essas ações a pesquisa busca padrões que sejam adaptáveis para este meio e que ainda possa ter caráter sustentável provocando reforços na formação dos ribeirinhos. A presente pesquisa busca apresentar uma forma de impedir a interrupção das aulas letivas no período escolar, ainda que em condições ambientais desfavoráveis. Aliada ao modelo é proposto alguns padrões de conforto elementar para a atividade acadêmica. Os materiais utilizados nas soluções propostas constituem uma adaptação sem grandes rupturas no modo ribeirinho de viver. Assim o uso da madeira de maneira sustentável e outro material, bastante frequente nas cidades industrializadas, são aliados formando um compósito capaz de ter a resistência estrutural da madeira e a propriedade térmica das placas feitas com resíduos de Poliestireno Expandido (Isopor). Como resultado, foi demonstrada a viabilidade de um projeto sustentável de escola ribeirinha, capaz de atender as necessidades escolas ribeirinhas, como conforto no processo ensino-aprendizagem e ao mesmo tempo foi possível a adaptação à variabilidade hidrológica em áreas de difícil acesso como a região amazônica.
