CHANGES IN STRUCTURE AND CHEMISTRY OF CEMENT MORTARS STRESSED BY A SODIUM CHLORIDE SOLUTION
Cement mortars, one-sidedly stressed by a sodium chloride solution of 20% for 140 days, show a marked area at a distance from the surface of nearly 30 mm. Its position is reflected in concentration profiles of the water soluble and nitric acid soluble parts of chloride, sulphate, sodium, potassium and aluminium, in the mineral content as well as in the pore size distribution. This could serve as the starting point for deteriorations caused by cycles of freezing and thawing connection with deicing salts, because destroying mechanisms could easily attack here. Further studies must be carried out and the observation of stressed cement mortars and concretes has to be intensified to get a better insight into the principles and the mechanisms of such processes.
