“…A similar experiment to that described in the previous section was performed with the use of SO 2 35 S. Radioactive 35 S is aˇ-emitter with a half-life of 87 day and the maximum energy ofˇ-particles is 167 keV. So far as we are aware, knowledge 35 SO 2 has not previously been used for simulation of sandstone weathering.…”

The aim of this work was to study the deterioration of various kinds of sandstone due to acid rain and SO 2 gas. The samples were taken from three quarries in Poland and one sample was from a tomb about 100 years old. To elucidate the mechanism of stone deterioration, simple experiments were performed. The sandstone samples were immersed for several weeks in SO 2 aqueous solution of pH ≈ 4. Similar experiments were performed using SO 2 aqueous solution of pH ≈ 1.5. The concentrations of Ca, Mg and Fe leached from the sandstone samples were measured with TXRF. An additional experiment was carried out with the use of radioactive 35 SO 2 . The samples were exposed to both 35 SO 2 aqueous solution and to 35 SO 2 gas. The autoradiograms obtained from the sample cross-sections indicated that sulfur penetrated to the interior parts of sandstone samples, especially from SO 2 gas.

“…Weathering conditions like atmospheric pollution, salty groundwater absorption are the main reasons for the deterioration of historical buildings [1]. Many works were on the deterioration of marble and limestone [2][3][4][5][6][7][8]. The improvement, strengthening, and protection of ancient buildings are attractive and having great intense in a lot of societies.…”

The uniaxial compressive strength is an important parameter in selecting and design of rock and brittles structure. Protection of ancient monuments or historic structure has a great intense in material science point of view. Limestone is commonly rock material which has a great sense in historical buildings and temples. The strength of this material may be influenced by natural weathering like moisture, rains and varying temperature. Samples of ancient limestone rock are coated with Paraloid B44, Paraloid B72, ethyl silicate and Wacker OH100. The results concluded that both Wacker OH100 and Paraloid B44 coating material have more efficient and give considerable protection when the sample is immersed in salinity water for a week. The compressive strength of limestone decreases due to water action. Water absorption, porosity, and rock density are enhanced with the coating process.
