Modeling Corrosion Resistance of Reinforced Concrete Structures

A bare pavement policy for roads and highways initiated in the United States in the 1950’s has lead to a significant use of road de-icing salts during winter maintenance periods which has accelerated deterioration of reinforced concrete bridge structures. The cause is due to the now well recognized chloride induced corrosion of the plain (black) reinforcing steel resulting in spalling of the concrete cover. A Monte Carlo probability analysis was performed for three types of reinforcing steel based on the condition of the reinforced concrete bridge deck and the chloride exposure distribution for the State of Virginia. The diffusion of this chloride loading into concrete decks and its effects on service life of epoxy-coated rebar batch galvanized steel rebar and 316LN stainless steel rebar was then calculated. The behavior of chloride diffusion was considered for initial surface crack densities of 0 3 6 and 12% of the deck area. A low-permeability concrete typical of present practice in Virginia was used. The total present cost (TPC) and life-cycle cost (LCC) figures show that galvanized steel rebar provides the most cost-effective protection for reinforced bridge decks with a 100 year life.

Effect of surface contamination on the corrosion performance of thermally sprayed aluminium coating in synthetic seawater

Product Number: 51323-19138-SG

Author: Adriana Castro-Vargas, Shiladitya Paul

Publication Date: 2023

$20.00

Coating standards specify the required surface conditions needed prior to coating. A maximum amount of soluble salts of 20 mg/m2 is widely adopted as acceptation criteria, according to standard NORSOK M-5011. However, meeting these requirements for thermal spray aluminium coatings (TSA) in offshore environments is challenging due to the ubiquitous nature of water-soluble salts.

Air Barrier Testing of Concrete Masonry Assemblies and the Effect of Surface Coatings on Air Permanence

Product Number: 41212-685-SG

Author: Nicholas Lang, Jason Thompson

Publication Date: 2012

$20.00

Model building codes and standards have begun adopting new energy efficiency requirements for building envelopes, including more quantifiable assessment of the air permeance characteristics of the materials and assemblies used in the building envelope. This research effort was initiated to understand and quantify the air leakage mechanisms of single wythe concrete masonry construction, which is commonly used in exterior building envelopes.

Study of Minimal Surface Preparation for Various Patch Repair Coating Products Applied under the Minimum Allowable Temperatures

Product Number: 51324-21005-SG

Patch repair coating products provide cost-effective solutions for restoring small to medium-sized damages in mainline coatings to extend the lifespan of pipelines. Some coating products are specially designed to tolerate reduced surface conditions while providing the adequate corrosion protection performance. Due to easy mobilization and relatively inexpensive, power tool cleaning is commonly used in the field to prepare surfaces for small area repairs. During field coating work, adverse weather conditions are often encountered. However, little data were publicly available to support if the minimal surface recommended by the product data sheet (PDS) is also suitable for the coating applied under the minimum allowable temperature. In addition, the effect of the similar surface level produced by different power tools on the corrosion resistance of the same coating is rarely reported. This paper aims to address these gaps. Four commercially available coating products were selected to examine their potentials as patch repairs, including one liquid-applied epoxy coating, one butyl-based sealant product, and two viscoelastic coating products. Test samples were prepared using a rust grade C steel pipe section. Different power tools such as wire brush, rotary sander, flap disc, and bristle blaster were used to create SSPC-SP3, SSPC-SP11, and SSPC-SP15 surfaces. All four products were applied and cured at the minimum allowable temperatures specified in their respective PDS or recommended by the manufacturers. A 14-day cathodic disbondment (CD) test was employed to rule out the improper surfaces or power tools, and the next higher surface level was then considered as potentially suitable. The long-term performance characteristics of these coating products on the established minimal surfaces under the minimum allowable application temperatures were evaluated using the selected critical tests from CSA Z245.30 standards.
