Abstract:
In view of the durability of reclaimed aggregate mixed with seawater, effects of corrosion inhibitors on mechanical
properties and corrosion behavior of recycled mortar mixed with seawater were analyzed and the mechanism was revealed
through microscopic experiments such as X-ray diffraction analysis ( XRD) and mercury intrusion ( MIP) . The results show
that recycled mortar mixed with seawater has a fast corrosion speed in the early stage, and then the corrosion speed slows
down after 7 d and gradually tends to passivation. In addition, aminomethyl propanol has an adverse effect on mechanical
properties of the mort
