Compilation of Alternative Building Components and Common Distresses Found Through Building Condition Assessment

The need of analysing the deterioration of the building structure and building component is very important now days. The degradation of building materials is defined as the gradual, spontaneous, slow process in which the material losses its own characteristic properties due to various Physical, Chemical and Environmental action. There are lots of factors which affects the degradation of the building materials. Degradation factors or agents can be defined as any of the group of factors that can affect the performance of a building material, component or system. These factors are classified according to their nature like mechanical, chemical, physical, biological, and environmental. The physical degradation is occurs due to physical forces. The chemical degradation is due to the reaction with the environmental components. In bio corrosion degradation the material is damaged due to the action of animals, plants, microorganisms. The degradation mechanism is very important term in degradation of building materials. The degradation mechanism of the building materials is defined as the sequence of chemical, mechanical or physical changes that lead to detrimental changes in one or more properties of the building material when exposed to one or more degradation factors.
