Mechanical parameters of different kinds of renders exposed to sodium sulfate solution
Original language description
This work is focused on the investigation of the effect of 5% water solution of sodium sulfate and the reference environment of distilled water on changes of mechanical resistivity of commercial dry render mixtures. Within the experimental testing, the prism specimens cured 28 days in humid and stable conditions were immersed in water or sodium sulfate solution. At specific time intervals, the particular specimens were collected, dried to constant mass and subjected to the strength tests. The maximal time of specimen exposure to moisture and salt action was 140 days. All studied renders improved their mechanical resistance with time of curing in water. The obtained data revealed the high capacity of porous space of tested renders for salt accumulation. For shorter times of exposure to salt action, all studied materials exhibited improvement in mechanical resistance. On the other hand, after the full filling of porous space, the evoked crystallization pressures led to the decrease in mechanical strength. However, one type of studied renders originally designed for restoration of salt laden historical masonry maintained its mechanical properties even after 140 days of sulfate solution exposure.
