Abstract
Building materials and their durability and aging are essential to the performance of buildings and their building physical aspects over time. Accelerated climate aging investigations are carried out in order to study the durability of various building materials in a substantial shorter time span than natural weather aging would have allowed. Climate parameters such as temperature that includes freezing/thawing cycles, relative air humidity, water spray amount, solar and/or ultraviolet (UV) radiation and exposure duration are controlled in different climate aging apparatuses. Various aging processes in building materials, aging both by natural and accelerated climate exposure, may be studied in an attenuated total reflectance (ATR) Fourier transform infrared (FTIR) radiation analysis following the decomposition and/or formation of chemical bonds in these building materials and products.Keywords
