Previous issue date: 2018-07-16 / The use of waste incorporated in building materials has been pointed out as an alternative for more adequate disposal of solid waste. Among the wastes generated in Brazil, are the glass. Less than half of the glass bottles produced in Brazil are recycled. In the present work the influence of the use of waste glass of brown bottles, crushed, as partial substitute of the natural sand, in the production of mortars was evaluated. The substitution contents evaluated were 10, 20 and 30%, by mass, in addition to the reference mortar (without waste glass). The properties of the mortars in the fresh state were evaluated (workability, specific mass and incorporated air content) and also in the hardened state (flexural tensile strength, compressive strength, water absorption, void index, specific mass and alkali-silica reactivity). The results of the tests indicated that the use of waste glass bottles, replacing the natural aggregate, did not alter the fluidity of the mortars, but decreased the density and increased the content of incorporated air. The incorporation of the waste provided an increase in the tensile strengths in flexion and compression, in relation to the reference mortar. With respect to the possible alkali-silica reactivity, it was verified that the mortars with the waste glass bottle did not exceed the expansion limit established in accordance with NBR 15577-4 (ABNT, 2009). Based on the results it was concluded that it is possible to use up to 30% of waste glass of brown bottles, replacing the natural sand. / A utiliza??o de res?duos incorporados ? materiais de constru??o vem sendo apontada como uma alternativa para destina??o mais adequada dos res?duos s?lidos. Dentre os res?duos gerados no Brasil, est?o os de vidro. Menos da metade das embalagens de vidro produzidas no Brasil s?o recicladas. No presente trabalho foi avaliado a influ?ncia da utiliza??o de res?duo de vidro de garrafas de cor marrom, triturado, como substituto parcial do agregado mi?do natural, na produ??o de argamassas. Os teores de substitui??o avaliados foram de 10, 20 e 30%, em massa, al?m da argamassa de refer?ncia (sem res?duo). Foram analisadas propriedades das argamassas no estado fresco (trabalhabilidade, massa espec?fica e teor de ar incorporado) e no estado endurecido (resist?ncia ? tra??o na flex?o, resist?ncia ? compress?o, absor??o de ?gua, ?ndice de vazios, massa espec?fica e reatividade ?lcali-s?lica). Os resultados dos ensaios indicaram que o uso de res?duo de vidro de garrafa, em substitui??o ao agregado natural, n?o alterou a fluidez das argamassas, mas diminuiu a densidade e aumentou o teor de ar incorporado. A incorpora??o do res?duo proporcionou aumento nas resist?ncias ? tra??o na flex?o e ? compress?o, comparado ? argamassa de refer?ncia. Com rela??o ? poss?vel reatividade ?lcali-s?lica, verificou-se que as argamassas com o res?duo de vidro de garrafa n?o excederam o limite de expans?o estabelecido conforme a NBR 15577-4 (ABNT, 2009). Com base nos resultados concluiu-se que ? poss?vel utilizar at? 30% de res?duo de garrafa de vidro de cor marrom, em substitui??o ao agregado natural.
