Test and prediction of chloride diffusion in recycled aggregate concrete

XIAO Jian Zhuang;YING Jing Wei;TAM Vivian W.Y;GILBERT Ian R;Department of Structural Engineering, College of Cvil Engineering, Tongji University;School of Civil Engineering and Architecture, Guangxi University;University of Western Sydney, School of Computing, Engineering and Mathematics, Locked Bag 1797,Penrith, NSW 2751, Australia;School of Civil and Environmental Engineering, The University of New South Wales;  
Recycled aggregate concrete(RAC) specimens with different recycled coarse aggregate replacement ratios by mass(R) are fully immersed in a 10% chloride solution for 235 days. Both free chloride concentration(Cf) and total chloride concentration(Ct) are then measured employing a rapid chloride test(RCT) system. The Fick's second diffusion law is verified by the test data and used to predict chloride concentration distribution at different immersion periods. Additionally, pore structures of the new and old mortar in RAC are tested by mercury intrusion porosimetry(MIP). It is found that binding chloride concentration(Cb) linearly increases with Cf. In natural aggregate concrete(NAC), Cf is obviously smaller than that in the RAC in the same testing environment and this is different from the test results of Ct and Cb. Furthermore, the effects of R on the chloride concentration of RAC become severe for specimens subjected to long immersion periods, which can be explained in terms of the pore structures of the new mortar and old adhesive mortar in RAC.
