Sustainability of civil infrastructure construction can in part be attained by better testing to identify important material characteristics that affect durability. The quality of the concrete in reinforced concrete structures is a primary factor that enhances corrosion durability of reinforced concrete structures. The concrete may be assessed for quality control using methods such as bulk ion diffusivity tests, accelerated electrical migration tests, and electrical resistivity. There is interest in non-destructive in-situ testing for assessment of structures in service. In this study, preliminary tests were conducted to characterize the durability of concrete using a water permeation test, acoustic testing, as well as electrochemical impedance spectroscopy. Test results showed that the electrical properties of the hardened concrete can be assessed by electrochemical impedance spectroscopy where a high frequency impedance loop (relating to the bulk material and internal moisture content) can be discerned. The concretes with lower water-to-cement ratio and larger coarse aggregates showed larger resonant frequency values that can be attributed to greater developed stiffness. A water permeation test was also demonstrated to differentiate internal moisture conditions, and its results (described by a decay factor derived from mass and energy balance) was well correlated to its concrete electrical parameters.

Pre-Manufactured Architectural Fire Protection

Product Number: 41210-533-SG
Author: Bill Dempster
Publication Date: 2010

A recent technology has been introduced where improved mechanical durability and aesthetically pleasing finish is achieved using pre-manufactured intumescent fire protection. This paper will detail how the pre-manufactured intumescent technology will provide an attractive alternative to spray application to achieve up to 2-hour rating with simple installation techniques that result in ultra smooth, no orange peel finish. This alternative process can be used on new construction, maintenance and building retrofits with little disruption on the job site.

Newly constructed Stainless Steel Pipes experienced multiple leaks during commissioning. The different sizes pipe were constructed of 316L and 304L stainless steel at one of the Saudi Basic Industries Corporation (SABIC) affiliates. A failure investigation was performed to identify the root cause of the leaks. Samples were cut out of the pipes for analytical study. Scanning Electron Microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS) was used to study the corrosion damage morphology and the chemical compositions of the corrosion products. Cross sectional samples, out of the pipes, were prepared for Metallographic examinations. XRF (X-Ray Fluorescence Spectrometry) and carbon/sulfur analyzer was used to identify the chemical composition of the pipes material. The failure investigation suggests that, improper welding, mothballing and lay-up of the piping network after hydrotesting promoted Microbiologically Influenced Corrosion (MIC).

The refining industry has made significant strides in technology and materials science, resulting in increased efficiency and reliability of various refinery units. Despite these advancements, unexpected failures persist, leading to costly downtime and potential safety hazards. A recent instance of premature failure in a newly commissioned Naphtha Hydrotreating unit (NHT) highlights the challenges that still exist in maintaining the integrity of critical infrastructure.

Because process shutdowns are expensive, it is desirable to speed up the turn-around time when applying protective coating systems on concrete. Rapid installation of surfacing materials on concrete can be problematical due to inadequate surface preparation, residual moisture, low surface tensile strength, and poor compatibility between the concrete substrate repair materials and the protective coating system.

A bridge coatings specification can be a complex and sometimes confusing document to navigate through. Yet it is regarded as the rulebook for quality control and quality assurance personnel responsible for inspecting the quality of work. An inspection plan is a tool that can make the process of understanding the inspection checkpoints invoked by a bridge coating specification more streamlined and can be a key communication tool for contractor and inspection personnel.

The practice of lining concrete substrates has increased exponentially over the past thirty (30) years, most notably in the wastewater treatment industry. Environmental regulations, coupled with changes to treatment processes, have resulted in far more severe environments in which concrete can and will corrode.

Duplex systems, also known as painting over hot dip galvanized steel, are extremely effective corrosion protection systems. However, careful surface preparation techniques need to be used to alleviate potential coating failures. The age and characteristics of the galvanized coating should be used to determine what type of surface preparation is needed. Surface preparation should develop an anchor profile for the paint without removing the zinc coating.
