AbstractThis research will implement a concrete base of recycled glass. With this new attempt to give new meaning to the civil works, thinking about the environment and providing significant advances in the manufacture of concrete with different materials or traditional. With the manufacture of this type of concrete may be building different types of civil works, primarily those that favor the poorest communities as they could use recycled material in the manufacture of masonry units to allow the construction of social housing involving the community in recycling campaigns, and obtaining the quantities of glass required for the preparation of such mixtures. This type of concrete has been little research and this project would be providing and marking the beginning of a research process in the country relating to concrete made with recycled glass. The investigation Was a concrete, from Two Different mix designs, Incorporating the glass instead of coarse Aggregate, cement, fine Aggregate and water. To achieve this new concrete is carried out a series of tests of concrete cylinders in standard sizes and procedures meet the standards INVIAS, NTC and NRS 98. The standards used, we suggest the use of granulometric characteristics curves, which were taken as reference for controlling the materials used by us in the mixtures used. The characteristic curves are taken in Colombia, incialmenmte planted by fuller and thomson and subsequently amended by Bolomey. For the glass, not had any previous reference, for this reason the grading curve of the glass was collected using a conventional grading test. Once we know the characteristics of each material were prepared two mix designs complying with necessary regulations. With these designs were made after the specimens would be tested by testing the compressive strength in the laboratory, and thus know the resistance to the arrival of the proposed designs. The proposed mix designs were 2500 and 3000 psi respectively, and the results were approximate to that proposal.
