Mar 29, 2013  Improvement of tensile strength with the addition of RCA would usually be associated with an improved elasticity; however, because the “recycled aggregates are more prone to deformation than raw aggregates,” the weakness of the aggregate reduces the Young’s modulus for concrete when RCA is used (Exteberria et al. 2007). Generally, Young ...
