Avaliação do desempenho de argamassas incorporadas com pó de vidro.

Abstract

Civil construction is one of the indicators of economic and social growth in a country. Its advancement will imply a greater consumption of mortar, which is a material of extreme importance in this sector because it has many applications such as laying, sealing, waterproofing, regularization and surface finishing. In this way, several studies are being developed, aiming at the incorporation of recycled materials in mixtures of mortars. And among the waste generated in the industry and in the area of construction is glass, which is a material that has gained space in architecture and civil construction and has been used on a large scale, as well as being resistant, it transmits beauty, harmony and lightness to the present constructions. However, although glass is a fully recyclable material, when discarded in the environment can take decades to decompose. In this sense, this study has as main objective to evaluate the performance of mortars incorporated with glass powder. 5 x 10 cm will be molded to study the physical and mechanical properties of the reference mortar and with sand substitution at 20 and 30% glass dust at ages 7, 14 and 28 days. It was observed that the mortars embedded with glass powder absorbed more water than the reference mortars, but the compressive strength at both incorporation contents was greater than double when compared to the reference trait. It was verified that, it caused an increase of the absorption in the mortars.
