Abstract:

© 2017, Editorial Department of Journal of Hunan University. All right reserved. The dynamic mechanical performances of recycled aggregate concrete (RAC) incorporating with 1% to 2% nano-SiO2 or nano-CaCO3 were tested by Split Hopkinson Pressure Bar (SHPB). The effects of different kind is of nanoparticles and different dosages on the mechanical performances of RAC were investigated. The results revealed that RACs with nano-SiO2 and nano-CaCO3 all zhowed higher dynamic compressive strength than the control RAC, and the nano-SiO2 was more effectire than nano-CaCO3 in enhancing the dynamic compressive strength of RAC. But RACs with high dosage of nano-SiO2 or nano-CaCO3 usually showed lower dynamic compressive strength than that of low dosage one, and the RAC incorporating with 1% nano-SiO2 achieved the highest dynamic compressive strength. Nano-CaCO3 exhibited more advantage in improving the deformation performance and energy absorption capacity of RAC. Both nano-SiO2 modified RAC and nano-CaCO3 modified RAC showed lower dynamic increase factor than control RAC.
