WebApr 11, 2012 · Abstract. This study tries to reveal the carbonation behavior when recycled coarse aggregates (RCAs) are used to mix new concrete. Six series of tests including 22 groups of recycled aggregate concrete (RAC) specimens were carried out, in which the effects of the water/binder (w/b) ratios, the binder content, the types of mineral … WebThe modeled recycled aggregate concrete (MRAC) which is an idealized model for the real recycled aggregate concrete (RAC) was used in this study. The MRCAs prepared with two types of old mortars were modified by an accelerated carbonation process. ...
