Comparison between the Effects of Normal Rain and Acid Rain on Calcareous Stones under Laboratory Simulation

Acid rain is a problem that despite efforts to reduce atmospheric pollution, continues impact not only countries where there high production of pollutants, but also transboundary areas which the pollutants are transported. In addition its effects on human health, infrastructure and consequences this entails. This study effect acid calcareous materials highlights need for protection buildings constructed from these materials, many part cultural heritage. The caused by were studied using simulator whose features allow simulation natural conditions as realistically possible. same way, coating synthesized nanomaterials, has been shown serve against degradation rain, was analyzed. long-lasting stone material, type avoids replacement elements recurrent cleaning degraded parts. It accumulation parts ground, transport personnel, work raw thereby contributing reduction carbon footprint water savings, in turn reduces cause rain.
