Changes in physical chemical properties as a function of ageing are assessed using traditional standard quality control tests, electrochemical impedance spectroscopy (EIS) and optical and electron microscopy, and durability is estimated on the basis of gravimetric data.
Numerical simulation of transport processes and the resulting chemical reactions in building materials is a versatile tool to estimate durability and corrosion processes of structures.
The effect of those phenomena in the receiver durability must be estimated from long-term aging tests, which are best carried out in a solar concentration facility.
In infrastructure containing concrete, such as bridges and tunnels, crack widths and patterns on surfaces are two of the most important signs used to estimate durability.
The oxygen diffusivity is of particular quantitative parameter for estimating durability performance quantitatively and for taking into account the effect of oxygen on calculation of service life of concrete.
A new system suggested in this study, Fuzzy-RES, is used to estimate durability of the volcanic rocks stonewalls moderated landscape built in 1970 in Karadeniz Technical University (KTU), Trabzon NE Turkey.
The evaluation of resistance to chloride ion penetration recommended by NT Build 492 (The Rapid Chloride Migration Test) (Nordtest Method NT Build 492 1999) is "Electrical Indication of Concretes Ability to Resist Chloride Ion Penetration" which can estimates the durability of concrete structures using the level of resistance to chloride ion penetration.
The proposed formulation is simple, yet realistic which can be used for estimating quantitative durability performance and reasonable durability design of concrete structures.
Methods to estimate fatigue durability are considered and the influence on durability of various factors is analysed.
To estimate the durability and reliability of a structural component its design loading spectrum must be defined.
