The effects of the damp diffusion through the gas concrete based external walls

ABSTRACT One of the building shell parts the external walls' components, their functions in a building and materials were studied. The gas concrete's, which has used to create external walls and the gas concrete based external walls' physical, mechanical and strength properties were researched separately. The effects of the water in building materials and the damp diffusion through the materials were studied and the possibility of condensation, which is the cause of the harmless result of different surrounding conditions, was found. Damp diffusion and condensation calculation methods were researched and the examples were determined. Besides the formulations The Thermal Insulation Regulations of Buildings' Calculation Program 2,0 was used to calculate the damp diffusion effects which is prepared by GÜB (Gazbeton Üreticileri Birliği-Gas Concrete Producers Association) based on TS 825 and the calculation results were determined by tables. Using by this program brick based and lightweight concrete based etc. external walls' diffusion calculation were studied too and comparing the results created the conclusion. Key Words: External walls, building materials, gas concrete, damp diffusion, condensation. Xll
