Chemical Changes of Cement Caused by Aggressive Environment

摘要

The chemical changes of cement structures exposed to aggressive environments are explored in this paper. In the predetermined time intervals the influence of the aggressive liquid, namely 5% wt. non-flowing sulphate solution, on mineralogical composition was tested. The chemical changes caused by corrosive sulphate environment on the testing specimens were determined in dependence on the different type of cement. From the results obtained follows that different kind of cement has impact on the sulphate resistance.
