... ABSTRACT The construction of a port expansion project in Arabian Gulf for a major operator included the surface-based structures such as capping beams and reinforced concrete piles. In 2009, a criticality assessment study was conducted that established the requirement of an impressed current...

... ABSTRACT Reinforced concrete cooling towers exposed to harsh operating environments can develop severe corrosion of embedded steel reinforcing, concrete delamination and spalling. Condition assessment of cooling towers is challenging due to their size, geometry and operational constraints...

.... If these different metals are in contact with each other inside reinforced concrete, galvanic corrosion between the outside stainless steel and the inside carbon steel is a concern. This work aims at comparing a performance of the UNS (1) S32304 lean-duplex stainless steel rebars in electrical contact with carbon...

... protection (CP) systems are well documented and recognized in the mitigation of corrosion related damage of steel reinforced concrete (RC) structures located in marine environments. However, in order to obtain suitable performance from these CP systems, it generally requires the structure to be exposed...

... Abstract Despite the low water to cementitious ratio used when preparing dry-cast reinforced concrete pipes, the concrete porosity of dry-cast reinforced concrete pipes has been found to range between 9 to 11 percent. These porosity values are higher than the porosity that is usually found...

... the calculated MAOP from 802 psi (5530 kPa) to 767 psi (5288 kPa) for three road crossings. The reduction in the pipeline pressure due to these three small sections at road crossings prompted the search for a solution to reinforce the sections to prevent a pressure reduction along the entire length of line...

... Abstract Exposure testing of concrete block or slab specimens by cyclic chloride ponding has been widely utilized for ranking or qualifying different reinforcement types and concrete mix designs and for projecting service performance. However, experimental issues such as inadequate bar end...

... Abstract Once corrosion of the reinforcing steel embedded in concrete has initiated, the corrosion propagation period is typically assumed to last five to ten years for carbon steel reinforcement. However, the duration of the corrosion propagation period could be significantly longer...

... Abstract Composite repair systems for pipe have been used successfully for leak sealing and reinforcement of pipework in the process industries. Their use has also expanded into pipeline integrity to address corrosion and mechanical damage, much like welded steel sleeves. Composite repairs...

... Abstract Mechanically stabilized earth (MSE) walls contain galvanized steel reinforcements that stabilize the fill by means of friction. After some time, the backfill may escape the wall or compact due to water ingress, forming voids that can compromise structural integrity. These voids may...

..., and two different concrete compositions with a w/cm of 0.41 (OPC and OPC+ 20% Fly Ash). These specimens have been within the corrosion propagation period for over three years. The third type of specimens are instrumented segments of reinforced concrete pipes, initially with no chlorides, but chlorides...

... Abstract The cooling water for the LNG processing facility returns to the sea through pipes to a seawater outfall weir box reinforced concrete structure where it passes over a weir to a channel and back to the sea. The water enters the outfall/discharge structure at high velocity...

... Abstract The Port Authority of Alleghany County (Pittsburgh), PA operates a garage facility where public transit busses are maintained and repaired. The roof of this garage is an open air reinforced concrete parking deck for employee and authority vehicles. This reinforced concrete slab has...

... ABSTRACT Fifteen years history of an operating cathodic protection system on a chloride contaminated atmospherically exposed conventionally reinforced concrete structure in Jeddah, Saudi Arabia conclusively proves that cathodic protection can significantly reduce the corrosion rate...

... ABSTRACT A first principles based equation from the literature was modified such that the cumulative distribution function (CDF) of Cl- concentration ([Cl-]) in concrete at the reinforcement depth after a given exposure time was calculated by numerical integration. The approach accommodates...
