Towards practical carbonation prediction and modelling for service life design of reinforced concrete structures
Amongst the scientific community, the interest on durability of concrete structures has been high for quite a long time of over 40 years. Of the various causes of degradation of concrete structures, corrosion is the most widespread durability problem and carbonation is one of the two causes of steel reinforcement corrosion. While much scientific understanding has been gained from the numerous c...
متن کاملCarbonation-induced Corrosion of Blended-cement Concrete Mix Designs for Highway Structures
Corrosion of concrete reinforcing steel in highway structures has traditionally been related to chloride ions. However, another cause of reinforcing steel corrosion is concrete carbonation which decreases the pH of the pore solution, Carbonation-induced corrosion tends to develop later and proceeds at slower rates than chloride-induced corrosion. Since very long service life goals are currently...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
A note on limitations of the use of accelerated concrete-carbonation tests for service-life predictions
Concrete carbonation is a process that can limit the lifetime of reinforced concrete structures. The resistance of concrete samples to carbonation is usually determined by accelerated tests under relatively high CO2-concentrations and a fixed relative humidity. No general agreement exists on whether and how the results of these experiments can be extrapolated to a natural setting. This note pre...
متن کاملHierarchical Life-Cycle Design of Concrete Structures
Concrete structures’ service life lasts decades. In order to deal with all the probable degradations and deteriorations in the whole life span, the concept of concrete structures’ Life-Cycle Design was introduced into China in the 1980s. However, until this day, Life-Cycle Design is still more of a concept to most structure designers and engineers, rather than a practical method. This paper pro...
