内容記述 | The rock and soil materials are used in worldwide buildings and heritages. For this management, famous building stones and concretes are often used. The appearance of the rock surface just after the construction is beautiful, however, it is suffering from the damage by weathering after dozens of years. Salts weathering - a reaction phenomenon with the salt solution is often regarded as a factor of the deterioration in such materials. Concerning concrete building, salt weathering is also observed on the pedestrian deck of Department of Engineering at Saitama University made in 1969. The observed main salt mineral was trona (Na3H(CO3)2・2H2O). Dissolution experiments were carried out using mortar tablet made with high early strength Portland cement. Four type solutions of pure water, 5%-CO2 solution and seawater were used for the experiments. In seawater experiment, white powdered products were appeared which is Brucite (Mg(OH)2) detected using XRD. On the contrary, calcite (CaCO3) was detected from the pure water experiment. From these results, wet-dry circumstance is necessary condition for crumbling of materials, whereas wet condition is decisively controlled what kind of salt minerals produced. | |||||
