The load-bearing performance of a RC simply supported beam bridge was comprehensively detected and evaluated. appearance detection results show that there is large area damaged exposed reinforcement in the main girder diaphragm plate bridge. detecting material condition state parameters durability insufficient, risk steel corrosion large, strength concrete poor. load test bearing capacity does ...

Corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (RC) structures deterioration in chloride-contaminated environments. As a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. The corrosion propagation phase is a ...

This paper assesses the impact of climate change on novel repair Ferrycarrig Bridge, a reinforced concrete (RC) marine bridge Ireland’s south-east coast. Five unique solutions were applied to seven crosshead beams Bridge during works in 2007. The two under examination herein involved replacement around sides with either 100% Ordinary Portland Cement (OPC) or which 60% cement was made up Ground ...

a new design for replacing a missing anterior tooth is described. in this article, a lingually fixed partial denture, its advantages, disadvantages, indication and contraindications have been explained. the ability of this design to replace a single missing central or lateral incisor is discussed.

A range of 1,3-di(metallocenyl)allylium salts [Mc(CH)(3)Mc'](+)[X](-) [Mc, Mc' = ferrocenyl (Fc), 2,3,4,5,1',2',3',4'-octamethylferrocen-1-yl (Fc' '), ruthenocenyl (Rc); X = BF(4), PF(6)] was synthesized by reaction of (2-lithiovinyl)metallocenes with formylmetallocenes, followed by treatment of the resulting alcohols with HX. Two salts with X = BAr'(4) [Ar' = 3,5-(CF(3))(2)C(6)H(3)] were synth...
