In the State of Rio Grande do Sul, the productive processes of semiprecious stones beneficiation such as agate produces wastes that demand a solution for the destination of the liabilities accumulated in the process. The use of waste and industrial by-products in the Civil Construction presents an excellent alternative to reduce the environmental impact and contributes for the sustainable development. This paper evaluates the influence of the use of agate waste as coarse aggregate in the compressive strength and the cement content for concrete produced with different mixes and recycled aggregate proportioning. For concrete production the mixes 1:3,5; 1:5,0 and 1:6,5 have been used, each one with three different recycled aggregate content: 25%, 50% and 75%. From the results of compressive strength test, diagrams for each recycled aggregate and cement content for different levels of compressive strength have been obtained. The analysis of the results showed that the use of agate waste in concrete is viable, and a 50% of recycled aggregate content presented the best performance.
