Abstract

Materials interact with pollutant in a very complex manner, the possibility of erosion, adsorption, desorption, transportation, deposition, and phase change will appear because of the interaction between the pollutant and the material surface. The effect of many other environmental effects also appear, like the effect of rain water in breaking away tiny rock particles (grit productivity). All the actions mentioned or any one of them may causes high damage or weaken the structure. This research highlights the importance of specific physical properties and material weakness, the effect of specific environmental factors (humidity, rain, and temperature) on materials, such as building materials and the potential occurrence places of cracks in the material, by knowing the quality of the material.
