Development Of Deficient Grout And Corrosion In Post-Tensioned Tendons Due To Water And Solute Transport

Product Number: 51322-17986-SG
Author: Rutambara Sonawane, Samanbar Permeh, Kingsley Lau
Publication Date: 2022
$20.00

Bridge construction utilizing post-tensioned (PT) tendon systems have become increasingly popular. 1-2 PT construction allows engineers greater options for the design of highway bridges and provides efficient structures with advantages in construction, economy, and serviceability. In bonded post stresses to the reinfotensioned systems, the introduction of rced concrete element is made through tensioned highstrength steel strand that are anchored and encapsulated in a cementitious grout within a tendon.3-4 The hardened grout allows development of the stress along the length of the tendon and also provides corrosion protection by the presence of the alkaline pore water to passivate the steel strand and by creating a barrier from external contaminants.

Microbiologically Influenced Corrosion (MIC) activities are mostly monitored by using canonical culture-based methods. However, these methods detect only culturable bacteria or require months of incubation to get results. To overcome this, molecular detection methods were developed for many of the MIC-causing microbes but were not available for Iron Reducing Bacteria (IRB) and Thiosulfate Reducing Bacteria (TRB). IRB and TRB are among the dominant group of microbes involved in corrosion and souring oil and gas infrastructures. In the present study, molecular probes were developed for IRB and TRB by targeting functional genes implicated in iron and thiosulfate reduction, respectively. Candidate gene sequences were retrieved from genome repository databases of pure isolates or metagenomic sequences. The sequences were aligned using bioinformatic software and primer-based probes were developed from conserved regions. Specificity and efficiency of the primers were validated by amplifying the sequences of target and non-target microbes using Quantitative Polymerase Chain Reaction (qPCR) methods. The probes successfully detected candidate microbes in biocorrosion samples collected from various gas processing facilities. The identified primer-based probes will help oil and gas industries to monitor MIC activities and develop timely management strategies to prevent undesirable microbial activities while improving system integrity and safety concerns.

Effective highway bridge design in terms of strength, service, and economy can be made using prestressed concrete including post-tensioned (PT) construction.1-2 Bonded PT bridge designs incorporate high strength steel strand within tendon ducts and encapsulated with cementitious grout.3-4 The grout provides a protective barrier layer for the steel by preventing direct exposure to the external environment as well as facilitating the natural development of a thin passive oxide layer on the steel surface in presence of the high grout pore water pH.

Seawater injection is commonly utilized for offshore wells to maintain or increase oil production; however, treatment for seawater before injection is always necessary to reduce or remove bacteria, dissolved oxygen, sulfate, and other impurities. Seawater typically has >2000 mg/L sulfate. Without proper sulfate removal, such high levels of sulfate can cause not only barium sulfate, strontium sulfate, and calcium sulfate scales, but also reservoir souring and H2S corrosion in the presence of sulfate reducing bacteria (SRB). Therefore, sulfate removal from seawater is critical before seawater injection into reservoir.

HISTORICAL DOCUMENT. This standard describes a test method to screen scale inhibitors for their ability to prevent precipitation of BaSO4 or SrSO4, or both, from oilfield brines.  This standard test method is intended to provide the user with a relative and quantitative measure of the ability of scale inhibitors to prevent (1) the formation and (2) the precipitation of solid BaSO4 or SrSO4, or both, which are necessary and critical stages in scale deposition
