Laboratory testing of concrete mixtures containing recycled aggregate.

Caption

General view of the different tests performed on concrete made with recycled aggregates: slump test to evaluate workability, compressive strength test, ultrasonic pulse velocity (UPV) measurement, air permeability test, and microstructural analysis using scanning electron microscopy (SEM). These tests confirmed that mixtures containing up to 20% recycled aggregate meet the requirements for structural applications.
