Glass recycling requires primary crushing of the material and subsequent granulation of the material through the sieving process, and the final product may not have the same qualities as the original material.An alternative for recycling glass by-products is in the production of concrete based on CP, where it has been successfully used as a substitute for fine aggregate and/or cementitious material; and although there is a large number of studies on this subject, most of them refer to the use of soda-lime glass, since it is the most common and widely available.In the present work, the effect of the use of industrial by-products based on VMG granulated ground glass is evaluated, in order to reduce the RAS, C02 and cause an improvement in the environment as well as a reduction in the costs of the same, which have been reported in general, more prone to present the harmful expansion product of the RAS, and for which it is necessary to use smaller particle sizes in order to avoid the harmful expansion product of the RAS.

The main objective of this research is to evaluate concrete made with recycled coarse aggregates (recycled concrete) and fine aggregates to determine their physical properties both in the fresh and solid state. The recycled aggregates were obtained from the demolition product of road slabs. The material obtained from the sampling was taken to the materials laboratory of the Universidad Autónoma de Tamaulipas, Tampico Campus, for material characterization tests. After the material characterization tests were performed on the recycled concrete aggregates, crushed gravel, and fine aggregates, the concrete mix design was carried out according to the ACI method, proposing a strength of F'c = 250 kg/cm2. Finally, the cylindrical specimens were tested in compression, obtaining a result of 100.16% of the design strength proposed for the standard sample, and 84.87% for the sample with recycled concrete. When evaluating the physical and mechanical properties of the recycled concrete, it was concluded that it does not comply with the standards, however, it can be used for secondary structures.
