Evaluating present condition of reinforced concrete (RC) structures is necessary for planning future maintenance and estimating residual service life of structures. A ten point (0-9) condition rating system is proposed for obtaining present condition of RC structures based on the measured values of concrete cover, carbonation depth and chloride concentration at rebar depth through in-situ tests...

Development and implementation of RABIT (Robotics Assisted Bridge Inspection Tool) in condition assessment concrete bridge decks is described. The system uses multiple nondestructive evaluation (NDE) technologies in characterization of three most common deterioration types: rebar corrosion, delamination, and concrete degradation. The system implements four NDE technologies: electrical resistivi...

The construction and inspection of reinforcement rebar currently rely entirely on manual work, which leads to problems such as high labor requirements costs. Rebar image detection using deep learning algorithms can be employed in quality intelligent construction; it check the number, spacing, diameter a site, guide robots complete tying. However, application relies large number datasets train m...

Introduction: Ferrocement is a low-cost material that can be utilized as replacement for expensive fiber-reinforced polymer (FRP), which generally used retrofitting structural and non-structural reinforced concrete members. The objective of this paper to investigate the effectiveness wire mesh in flexural members such beams. It also investigated capacity beams, are with partial or complete regu...

background: a major issue in many gene expressionstudies utilizing small amount of biological materials is thelimited quantity of rnapurified from clinical samples, which isoften used for rt-pcr or standard northern blot analysis.objectives: the smart cdna synthesis method and subsequentsmart-cdna-pcr technique was used to analyse 3genes in macroschizonts of theileria annulata in small lymphnod...

The effect of strain levels on the corrosion resistance an enamel-coated steel rebar is experimentally investigated in this study. Enamel coating was applied surface a by using wet process. A gauge attached coated to record and plastic container mounted for electrochemical tests. stress-corrosion test set-up designed conduct tensile tests simultaneously. considered include 0 µε, 300 600 900 µε ...
