In Peru it is possible to find 131,500 tons of glass containers discarded after use, of which only 1% is recovered, 52% is placed in landfills and 47% is disposed of in landfills or directly into the environment. It is believed that half of this waste is generated in Lima, however, this may be higher. This problem can be reduced by giving glass a second use within the cement industry, in addition to contributing to the environment. In this study, ground glass is used for concrete mixtures as a partial replacement for Type I and Type HS cement, with percentages of 5%, 10%, 15% and 20%, worked with a water-binder ratio of 0.45. The compressive strength, after being cured in water and in a MgSO4 solution, was measured for periods of 7, 28 and 90 days for both concretes (Type I and Type HS). The greatest increases for the conditions, water and sulfate, studied were 1.69% for the 10% replacement at 90 days for Type I immersed in water and 1.86% for the 10% replacement at 90 days for T1 immersed in sulfates, which is a positive indicator for concrete. Improvement in the workability of the concrete was observed when the replacement percentage increased, this reached an increase of 112%. The maximum expansion obtained was 0.111%, which does not exceed the maximum allowed according to the standard of 0.8%. In addition, the theoretical percentage of emissions avoided if this replacement were implemented was calculated. Therefore, a concrete with glass replacement in cement of up to 10% not only promotes the use of this waste but also provides greater compression resistance under normal conditions and also when subjected to sulfate attack.
