Research on recycled concrete and its utilization in building structures in China

Jianzhuang XIAO, Tao DING

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 3,   Pages 215-226 doi: 10.1007/s11709-013-0212-z

Abstract: current shaking table test research in China on structures built with recycled aggregate concrete (RACThe test results prove that it is feasible to use RAC as a structural material in seismic areas, withThis paper also presents several successful applications of RAC in civil and structural engineering projectsin China, which will serve to promote RAC as a global ecological structural material.

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 3,   Pages 746-759 doi: 10.1007/s11709-020-0635-2

Abstract: Recycled aggregate concrete (RAC) may own greater potential in CO uptake due to the faster carbonationA quantitative model was employed to predict the CO uptake of RAC in this study.The carbonation of RAC and the specific surface area of recycled coarse aggregates (RCAs) were testedThe CO uptake amount of 1 m C30 RAC within 50 years is 10.6, 13.8, 17.2, and 22.4 kg when the RCA replacementThe CO uptake by RCAs is remarkable and reaches 35.8%–64.3% of the total CO uptake by RAC when the

Three-scale stochastic homogenization of elastic recycled aggregate concrete based on nano-indentation digital images

Chen WANG, Yuching WU, Jianzhuang XIAO

Frontiers of Structural and Civil Engineering 2018, Volume 12, Issue 4,   Pages 461-473 doi: 10.1007/s11709-017-0441-7

Abstract: paper, three-scale stochastic elastic finite element analyses are made for recycled aggregate concrete (RACThe elastic property of RAC contains uncertainties across scales.Based on homogenization theory, effective stochastic elastic moduli of RAC at three different scalesThe microscopic randomness is taken into account, and correlations of RAC among five phases are investigated

Engineering 2023, Volume 29, Issue 10,   Pages 188-197 doi: 10.1016/j.eng.2023.03.017

Abstract:

In the past 20 years, recycled aggregate concrete (RAC), as a type of low-carbon concrete, has becomeHowever, the design methodology for RAC structural components remains a challenge.Consequently, demands for a unified design of natural aggregate concrete (NAC) and RAC components haveThe coefficient of variation of RAC strength is found to be generally higher than that of NAC strengthfor RAC components are proposed considering safety and reliability.
