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.
