摘要：
The main aim of this contribution is description of the static and the dynamic modulus of elasticity of concrete containing recycled aggregate. Recycled construction and demolition waste, especially recycled concrete, is able to use as an aggregate for concrete, but using of recycled aggregate has a negative impact of concrete characteristic. This paper presents results of non-destructive measurement of recycled aggregate concrete properties. Series of concrete samples with 100% replacement ratios of coarse natural aggregate by coarse recycled aggregate from different sources were prepared for this study. The static and the dynamic modulus of elasticity were investigated on specimens 100 x 100 x 400 mm. All tested mixtures were also tested on compressive strength.
