Abstract
Of the total waste concrete only about 14% of all waste concrete is made into aggregate and recycled. To promote the use of recycled concrete aggregates (RCA), flexural tests of 28 reinforced high-strength and normal-strength concrete beams were performed. The main objectives of this research were the structural investigation of flexural performance and the evaluation of the potential application of RCA for concrete structures. In comparing the RCA specimens to the natural aggregate specimens, the overall crack patterns were similar to each other. The flexural behavior was also not affected significantly by the use of RCA.Keywords
