Critical Index Determination Method on Visual Assessment of Concrete Damage for Buildings

Visual Assessment is an initial assessment of the concrete condition of a building (non-destructive test). There are multiple types of concrete damage, so it is necessary to identify the type of damage that could be assessed visually. To find out the critical level of each type of concrete damage, a Critical Index method is needed. Based on the analysis sets, the range of Critical Index is 0 to 4. The value of 0 indicates a very good Critical Index of concrete, whereas the value of 4 shows a very bad Critical Index of concrete. The value of 0 can be interpreted as the concrete is not damaged and 4 means that the concrete is not acceptable. Determination of Critical Index method can be used to determine the Critical Index of any type of damage to the concrete in a building and to determine the level of damage according to each type of damage.
