Paper Title:
Resistance of Hydrated Cement Paste to Acid Attack and Kinetics Analysis of Corrosion
  Abstract

The resistance of hydrated cement paste (HCP) to acid attack was investigated. Three groups of blended cementitious materials were designed, binary binder A (cement and slag), ternary binder B (cement, slag and silica fume), and quaternary binder C (polymer modified ternary binder). According to a series of designed experiments, acid resistance of HCP was tested by acid consumption, mass loss and corrosion depth of specimens. In the study, ternary binder B shows superior resistance to acid attack. The advantage of polymer modification is unobvious. Furthermore, the variability of acid corrosion depth d with time t was analyzed specially for the foundation of degradation model. Kinetics equation of acid corrosion was established in form of d=K•tn to predict HCP corrosion depth at specific age, which provides available references for durability analysis and engineering design of concrete structures.
