Caracterización físico-mecánica del hormigón estructural fabricado con áridos reciclados: comparativa experimental con sustitución de áridos finos y gruesos = Physical-mechanical characterization of the structural concrete made with recycled aggregates: e

This work studies the mechanical and physical properties of structural concretes made by recycled aggregates obtained from construction and demolition waste. Mixes with a specific water/cement ratio and a similar coarse and fine aggregate substitution have been selected. Results from slump, compressive strength, splitting tensile strength, static modulus of elasticity, shrinkage strain, bulk density and water absorption tests have been compared. The data show that the most affected properties because of natural aggregate substitution for recycled aggregates are workability, modulus of elasticity, shrinkage strain and water absorption.
