TY - JOUR N2 - Recycling construction and demolition waste not only reduces project costs; and saves natural resources, but also solves the environmental threat caused by construction waste disposal. In this paper, C25 waste road concrete is used as an experimental material, the uniaxial compression strength and tensile splitting strength of C25 RAC whose coarse aggregate replacement rate is 0%, 25%, 50%, 75%, and 100% are tested under the condition that the water-to-cement ratio is 0.47, 0.55 and 0.61. The results show: (1) the uniaxial compression strength and tensile splitting strength decrease with the increase of RAC; (2) for concrete with the same water-to-cement ratio, when the coarse aggregate replacement rate changes from 0% to 50%, the uniaxial compression strength and tensile splitting strength of RAC changes slightly. When the coarse aggregate replacement rate changes from 50% to 100%, the uniaxial compression strength and tensile splitting strength of RAC decreases rapidly L1 - http://www.czasopisma.pan.pl/Content/103291/PDF/14%20An%20Investigation%20of%20Mechanical%20Properties%20of%20Recycled%20Coarse%20Aggregate%20Concrete.pdf L2 - http://www.czasopisma.pan.pl/Content/103291 PY - 2016 IS - No 4 / II EP - 34 KW - recycled coarse aggregate concrete KW - water-to-cement ratio KW - coarse aggregate replacement rate KW - uniaxial compression strength KW - tensile splitting strength A1 - Deng, X.H.
