Substituição parcial da areia pelo vidro moído na argamassa.

Abstract

The use of solid waste as an alternative to conventional materials in civil construction has been increasingly important in recent years, due to its economic and environmental benefits. Glass is a widely used material, but its improper disposal has negative impacts on the environment. Its use as a substitute is a solution to avoid improper disposal and contribute to the construction of more sustainable buildings, as it allows the reuse of materials and decreases the extraction of natural resources. This work studies the physicomechanical properties mortar with partial replacement of sand by glass in different proportions (12%, 24%, 36% and 48%) to assess possible changes in mortar properties in the fresh and hardened state. The methodology included laboratory tests and the comparison between different proportions of residues in the mortar in relation to the reference mortar. Index tests were carried out of consistency, flexural tensile strength and compressive strength, with 3 specimens for each trait, subjected to rupture at 7 and 28 days. The results showed themselves satisfactory in all proportions, presenting fluidity in all the mortars when compared with the reference. The 36% content showed the best mechanical performance, having an increase of 25% compared to reference mortar.
