| 1 | Recent studies on mechanical properties of recycled aggregate concrete in China-A review显示文摘Numerous experimental and theoretical studies on recycled aggregate concrete have been carried out in China in the past 10 years.This paper provides a comprehensive review of the related findings of research on the mechanical properties of RAC in China.The influences of the RCA on the strength and deformation characteristics of concrete,the statistical characteristics for the strength of RAC,fracture energy,stress-strain relationships under uniaxial compression,uniaxial tension as well as pure shear,and the residual strength of RAC after exposure to high temperatures,the bond between RAC and different kinds of steel rebar were also reviewed.Furthermore,some recent studies on the numerical simulation of the failure mechanism for RAC at the meso-structure level were discussed. | XIAO JianZhuang LI WenGui POON ChiSun | 2012 | Science China(Technological Sciences)2012，55，6： | 31 |

| 19 | Model investigation of the low-carbon MgO-treated soil foundation based on CO_(2) overall carbonation显示文摘The overall carbonation of MgO-admixed soil provides not only an efficient and environmentally friendly technique for improving soft ground but also a permanently safe solution for CO_(2) sequestration.To evaluate the carbon sequestration potential and promote the carbonation application in soil improvement,a laboratory-scale model investigation is designed under pressurized carbonation considering the influences of MgO dosage and CO_(2) ventilation mode(way).The temperature,dynamic resilience modulus,and dynamic cone penetration(DCP)were tested to assess the carbonation treatment effect.The physical,strength,and microscopic tests were also undertaken to reveal the evolution mechanisms of CO_(2) migration in the MgO-carbonated foundation.The results indicate that the temperature peaks of MgO-treated foundation emerge at w20 h during hydration,but occur at a distance of 0e25 cm from the gas source within 6 h during carbonation.The dynamic resilience moduli of the model foundation increase by more than two times after carbonation and the DCP indices reduce dramatically.As the distance from the gas inlet increases,the bearing capacity,strength,and carbon sequestration decrease,whereas the moisture content increases.Compared to the end ventilation,the middle ventilation produces a higher carbonation degree and a wider carbonation area.The cementation and filling of nesquehonite and dypingite/hydromagnesite are verified to be critical factors for carbonation evolution and enhancing mechanical performances.Finally,the overall carbonation model is described schematically in three stages of CO_(2) migration.The outcomes would help to facilitate the practical application of CO_(2) sequestration in soil treatment. | Guanghua Cai Songyu Liu Yuqing Zhong Chisun Poon Jiangshan Li | 2023 | Journal of Rock Mechanics and Geotechnical Engineering2023，15，11： | 0 |
