Moisture is a key component of concrete. It is critical to the curing and strengthening process of the product. It is however the use or misuse of this critical component that may cause expensive and unavoidable problems over the life of the floor
US Marines are known and respected the world over for their leadership ability. How do they do it? What do they know that enables them to be such successful leaders on active duty and then in the civilian sector? This paper, based on the book of the same name, reveals the nine essential behaviors that make up the foundation of leadership.
Modern design, manufacturing and field-testing specifications include surface profile and adhesion testing on the assumption that they are linked to long term corrosion prevention. There are a number of careful studies, dating back decades, that find no link between measurements of adhesion and (undercutting) corrosion performance, but other studies do, and the concept remains intuitively appealing and widely assumed.
Steel rebar in concrete is in a passive state due to the high pH of concrete. The hydroxyl (OH-) ions in highly alkaline concrete pore solution act as inhibitors and promote passive film stability, while chloride ions lead to passive film breakdown. Leckie and Uhlig1 first explained the counter effect of inhibitor action with chloride concentration. They proposed a competition between the inhibitor and chloride anions for adsorption on the passive surface.
Weakening of concrete structures by steel reinforcement corrosion is a concern. The paper represents results from an investigation involving testing of small scale prestressed concrete beams to correlate steel corrosion to global strain changes.
Duplex stainless steels (DSS) are an attractive alternative to conventional austenitic 300 series. They are becoming more and more present in industrial applications requiring high mechanical properties combined with good corrosion resistance. UNS S32202 is a lean duplex grade designed to guarantee corrosion resistance superior to that of 304L in most environments and even equivalent to 316L in NaCl environment at room temperature. Its yield strength is twice as high as 304L and 316L allowing thickness and weight reduction in structural components. With low nickel content (2.5%) and no molybdenum addition, the impact of raw material price fluctuation is reduced. It makes UNS S32202 suitable for a high number of applications including public transportation, building & construction, watersystems, liquid storage and pulp&paper industry.
The effectiveness of organic commercial migrating inhibitors on steel reinforcements corrosion. Four series of concrete specimens were cast. Two organic migrating inhibitors were applied. Free corrosion potential and corrosion rate of steel rebar were periodically monitored for five years. Results show that migrating inhibitors are not effective in reducing corrosion rate.
The National Shipbuilding Research Program (NSRP) is an industry-led, Navy-sponsored collaboration of U.S. shipyards working together to reduce the cost of building, operating and repairing Navy ships by improving productivity and quality through advanced technology and processes. In 2014 the NSRP Surface Preparation & Coatings Panel obtained approval from the Executive Control Board for funding of a project that would evaluate the latest in digital coating inspection instruments and their potential for cost savings in the inspection of Navy vessels.
