ABSTRACT
One of the consequences of the industrial expansion process is the generation of large amounts of waste. Among all the waste generated stand out the glass packaging, which is one of the materials with the longest decomposition present in landfills and other deposits. Among the different types of glass packaging that are used are the long neck bottles, which are today a major problem due to their disposal after use. In this context, in order to minimize this environmental problem, we highlight the construction sector, which is an excellent way to incorporate waste. The objective of this work is to study the viability of using long neck milled bottles to partially replace sand in the production of mortar. For this purpose, fresh consistency and flexural tensile strength, compressive strength and hardened capillary water absorption tests were performed. The percentages of replacement of fine aggregate by ground glass residue were 10, 15, 25 and 50 % at 7, 28, 63 and 91 days. As a result, in the mechanical strength tests, resistances were obtained statistically equal to or higher than the reference trait, and the highest strengths were obtained with the 50 % residue of ground glass. In the capillary water absorption test, all traces of mortar presented high coefficient of capillarity, being considered unsuitable for use in coating mortars.
