Today, the use of coarse recycled concrete aggregates is higher than before, but the fine fractions 0–4 mm and 0–8 mm still lack applications with an added value. The properties of fine recycled aggregates are worse than those of coarse recycled aggregates and they are less investigated compared to the coarse recycled aggregates.

The model considered the plasticity of concrete and the concretetoconcrete contact properties, and was found to agree with experimental data from shear transfer tests. The verified model was then used for a parametric study that investigated lateral reinforcement, concrete strength, and recycled coarse aggregate (RCA) replacement ratio.

Recently, recycled aggregate concrete (RAC) technology has become an effective way to utilize construction waste resources [11, 12]. By the socalled RAC technology [13–15], the construction waste can be recycled, crushed, washed, and graded and then mixed to form recycled aggregates with a certain proportion and grading. After that, the recycled aggregates are used to replace partially or completely .
