Transport Properties of Concrete
In this paper the main transport processes that take place in concrete are described. For each process a brief introduction to the physical mechanism is developed by giving examples of how they can contribute to the deterioration of concrete structures by, for example, enabling salt to reach the reinforcement. An example of the practical use of the theory is taken from the design of a waste con...
متن کاملFinite Element Modeling of Reinforced Concrete Beams Exposed to Fire
Abstract: The practical implementation of performance-based fire safety design of reinforced concrete (RC) structures hinges on the availability of accurate numerical simulation tools for the behavior of RC members exposed to fire. This paper presents a three-dimensional (3D) finite element (FE) model for the accurate prediction of both the thermal and the mechanical behavior of RC beams expose...
متن کاملExtracting Concrete Thermal Characteristics from Temperature Time History of RC Column Exposed to Standard Fire
A numerical method to identify thermal conductivity from time history of one-dimensional temperature variations in thermal unsteady-state is proposed. The numerical method considers the change of specific heat and thermal conductivity with respect to temperature. Fire test of reinforced concrete (RC) columns was conducted using a standard fire to obtain time history of temperature variations in...
متن کاملAnalysis of the Transport Properties of Tyre Fiber Modified Concrete
Problem statement: Nowadays, the use of waste tyre in concrete has become technically feasible and the tyre mixed concrete is light weight and called as rubberized concrete. Still the research is going on to explore basic engineering properties such as transport properties viz, acid absorption test, water absorption tests, impact resistance, modulus of elasticity, dynamic modulus and so on. In ...
متن کاملTowards a fragility assessment of a concrete column exposed to a real fire –
Fires can cause substantial damage to structures, both non-structural and structural, with economic losses of almost 1% GDP in developed countries. Whilst design codes allow engineers to design for the primary design driver, property protection is rarely, if ever, designed for. Quantification and design around property protection has been used for some time in the seismic community, particularl...
