Abstract: Recently, there has been increased use of calcium-nitrite and calcium-nitrate as the main components of chloride- and alkali-free anti-freezing agents to promote concrete hydration in cold weather concreting. As the amount of nitrite/nitrate-based accelerators increases, the hydration of tricalcium aluminate (C3A phase) and tricalcium silicate (C3S phase) in cement is accelerated, thereby improving the early strength of cement and effectively preventing initial frost damage. Nitrite/nitrate-based accelerators are used in larger amounts than usual in low temperature areas ◦ below −10 C. However, the correlation between the hydration process and strength development in concrete containing considerable nitrite/nitrate-based accelerators remains to be clearly identified.

  • How DCI Works
    ENGINEERING BULLETIN 5 DCI® How DCI works This engineering bulletin describes the role of corrosion inhibitors, and the way DCI® Corrosion Inhibitor controls the corrosion of steel reinforcement in concrete. The theory of corrosion is described in DCI Engineering Bulletin 1, What is Corrosion?. This bulletin is most informative if the reader has a basic understanding of corrosion or reads Engineering Bulletin 1 first. DCI Corrosion Inhibitor is a calcium nitrite-based solution. Calcium nitrite, Ca(NO2)2, is a well known inhibitor for systems requiring corrosion protection. Studies of structures in long-term service and extensive field and labora tory tests confirm its effectiveness in concrete. The Problem corrosion protection for all embedded steel and other metals. Unlike other inhibitors, calcium nitrite does not have Due to the high pH of concrete, steel in concrete is any negative effects on the physical properties of concrete. surrounded by a natural layer of iron oxide called the DCI corrosion inhibitor is classified as an ASTM C494 passivating layer, which protects the iron from rusting. Type C admixture. In the absence of aggressive ions such as chloride ions, corrosion of reinforcement does not take place. As Calcium nitrite protects steel in concrete by assisting chloride ions from saltwater or the natural defense that is already present. In an alkaline de-icing chemical reach the steel, however, they environment, steel forms an oxide from iron (Fe), oxygen undermine the oxide layer and the iron rusts. (O) and hydroxide ions (OH–). Initially, the oxide is formed with ferrous ions (Fe++). The ions are generated according In the protective ferric oxide layer that forms around to the equation: the reinforcing steel or prestressed strand, there are micro scopic ferrous oxide defects (Figure 1).

APPROVEDRedacted for privacy Department of Electrical Engineering. Redacted for privacy Dean of School of Engineering. TIE ELECTROLYTIC FIXATION of ATMOSPHERIC. ITITUCGEIT. Introduction, Much has been accomplished in the last few years toward the conservation of natural resourses, and in this work the engineer has taken a leading part. The prevention of unnecessary waste, the utilisation of hither-to useless "by-products, and the economic pro duction of the world's necessities are important fea tures of th1 s work. It is the latter phase with which this subject deals. A large percentage of the world's commercial fertilizer comes from the immense beds found in the Atacama Desert, in Chile. But as the demand for Chili Saltpeter is increasing rapidly from year to year, scien tists are already "beginning to look around for another source of supply when these fields fail. The following paper will be divided into three parts; First, A discission of the theory and economic principles Second, a resume of the current literature on the sub ject. Third, The construction and tests of a chamber pa tented after the Thomas and Barry Process. Part I. Theory and Economic.. Principles. If and electric discharge is passed through a gas or mixture of gases, different chemical reactions are produced ascording to the nature of the discharge. Thus, if a silent discharge is passed through atmospheric air, the oxygen ( C^ molecules).in~the air is changed into ozone, f O5 molecules).
