• Studies on recycled aggregatesbased concrete

    In this study various physical and mechanical properties of recycled concrete aggregates were examined Recycled concrete aggregates are different from natural aggregates and concrete made from them has specific properties The percentages of recycled concrete aggregates were varied and it was observed that properties such as compressive strength showed a decrease of up to 10% as the percentage of recycled concrete aggregates

  • Recycled Aggregate an overview | ScienceDirect Topics

    The use of recycled aggregate, in general terms, causes a reduction in concrete strength ( Poon, Shui, Lam, Fok, & Kou, 2004) and elastic modulus, larger creep, and shrinkage deformations ( DomingoCabo et al, 2009 ), as well as higher permeability of the concrete ( GómezSoberón, 2002 )

  • Evaluation of the Characteristics of Recycled

    Recycled aggregates with specific mass higher than 22 g/cm³, have high levels of rocks, resulting in concrete with mechanical behavior similar to those produced with natural aggregates [22] It is verified that all samples of recycled aggregates, except ARMB2 and ARMD, presented values higher than 22 g/cm 3 , therefore, they are theoretically able to offer good values of mechanical resistance to
