REAL-TIME MONITORING OF COVERCRETE RESPONSE TO ENVIRONMENTAL ACTION

摘要：

Currently,the most predominant process associated with deterioration of reinforcedconcrete structures is corrosion. Since it is the cover-zone concrete which protects the steelfrom the environment,the ability to study the protective qualities of the covercrete couldassist in assessing the current and future performance of the structure. To this end,a multi-electrode array was used to study the surface 50 mm of concrete specimens thereby allowing adetailed picture of the response of the covercrete to the changing environment,both in theshort-and long-term. In the current work,CEM Ⅰ,CEM Ⅱ/B-V and CEM Ⅲ/A cements wereused and comprised field studies on both mini-slabs and monoliths.
