The Influence of Chloride and Nitrite Solution Exposure on Mechanical Properties of Industrially Produced Plaster Mixtures

Abstract:

Lime and cement-lime industrially produced dry plaster mixtures are widely used building materials. These surface treatments can come into the contact with salt solutions which cause their degradation. On this account, the influence of calcium nitrate and calcium chloride water solution exposure on mechanical properties of several commercially produced mortars is researched in the paper. The prismatic specimens having dimensions of 40/40/160 mm are cured 28 days in humid environment. Then, the studied specimens are stored 112 days in both salt solutions and reference environment of distilled water. At specific time intervals, the compressive and bending strengths are measured and the obtained data are discussed.
