Corrosion study of mild steel, tor steel and CRS steel by weight loss method


ABSTRACT:

In present investigation an attempt has been made to investigate corrosion rate of mild steel, Tor steel and CRS steel in reinforced concrete. The five concrete block sites have been selected. The factor causing corrosion and conditions of the environment has been studied. Attempt has been made to consider conditions which will help to get greater protection against corrosion problem for industries as well as household articles.  

Introduction:

 Corrosion is the destructive attack on a metal or a metal alloy by chemical or electrochemical reaction with its environment . Metal and its alloys tend themselves to many engineering application because of their combination of lightness with strength, thermal and electrochemical conductivity, reflectivity and non toxic qualities . Iron is used in the form of stainless steel for making cutlery, hospital and food service equipment. Carbon steel is the most common, cheapest and most versatile metal used in industry. Due to wide range of applications of alloy in our day to day life. The corrosion study of metal in an analytical importance. Corrosion is disintegration of material into its constituent atom due to chemical reaction with its surroundings. The loss of electrons of metal reacting with water and oxygen. Weakening of iron due to oxidation of the iron atoms is a well known example of electrochemical corrosion.

 Although in this context, the term degradation is more common. Most structural alloys corrode merely from exposure to moisture in the air. But the process can be strongly affected by exposure to certain substances. Corrosion can be concentrated locally to form a pit or crack, or it can extend across a wide area to produce general deterioration. There are different factors influencing corrosion such as acids, oxidizing agents and temperature. Even though a number of factors are responsible for early distress in reinforced concrete structure it is observed that in the majority of cases it is because corrosion of steel. The problem is wide spread in India due to the peninsula being surrounded by sea, hot and humid climate and also aggressive environmental conditions created by industrial development of the country. Proposed work was under taken for the systematic study of corrosion.

Quantitative analysis of civetone and normuscone in secretion from Viverricula indica and in aromatic remedies by gas chromatography-mass spectrometry

Image
ABSTRACT : The quantitation of civetone and normuscone in small Indian civet (Viverricula indica Desmarest) secretion cultivated in Thailand was analyzed by gas chromatography- mass spectrometry (GC-MS). Three main chemical constituents of small Indian civet secretion were civetone, dihydrocivetone and normuscone. The contents of chemical constituents were different between male and female secretion. Civetone (23.6 ± 1.5 µg/mg of secretion) was a major chemical constituent in the female secretion while normuscone (52.1 ± 5.9 µg/mg of secretion) was a major in the male secretion. Both civetone and normuscone were found in civet fur but not in the feces. Aromatic remedies which claimed to use the small Indian civet secretion as an ingredient showed both civetone and normuscone. Linearity range of civetone was 0-50 µg/ml with a correlation coefficient of 0.9717, and of normuscone was 0-80 µg/ml with a correlation coefficient of 0.9965. The average recoveries were 97.3-98.0% in sec...

Antimicrobial activity of aqueous, ethanolic, methanolic, cyclohexanic extracts and essential oil of Nigella sativa seeds

Image
  ABSTRACT : Most of the bacterial pathogens are resistant to existing synthetic antibacterial agents demanding an increasing effort to seek effective phytochemicals as antibacterial agents against such pathogens. Nigella sativa L. (black cumin) seeds play an important role in folk medicine and some of its major constituents are reported to be pharmacologically active. In this present work, Nigellasativa seed extracts were obtained using maceration extraction by various solvents (water, ethanol, methanol, and cyclohexan). The antibacterial and antifungal effects of different extracts and essential oil of seeds were investigated by the agar diffusion method against two gram positive (Bacillus subtilis CIP52.62 ,Staphylococcus aureus CIP4.83) and three gram negative strains of bacteria (Escherichia coli CIP53.126 ,Pseudomonas aeroginosa CIP82.118, Salmonella abony CIP80.39) and one strain of fungi (Candida albicans CIP48.72). All the extracts and essential oil showed varying d...

Analysis of total phenols,total tannins and screening of phytocomponents in Indigofera aspalathoides (Shivanar Vembu) Vahl EX DC

Image
ABSTRACT: The plant Indigofera aspalathoides is popularly known as Sivanar vembu in Tamil belongs to the family fabaceae. The stem is traditionally used for various skin disorders and cancer. In the traditional medicinal system, the leaves, flowers and tender shoot are said to be cooling and demulcent, they are used in the form of decoction for leprosy and cancer affections. Qualitative and quantitative Phytocomponents test were screened in Indigofera aspalathoides. The total content of some important phytochemical constituents like phenols, tannins of Indigofera aspalathoides by studied using spectrophotometric methods. The results showed that the plant is rich in phenols (47.38±1.532) compare than Tannins (34.59±1.788).  Further details Home page URL : http://www.jocpr.com/ For more details PDF Link :  http://www.jocpr.com/articles/analysis-of-total-phenolstotal-tannins-and-screening-of-phytocomponents-in-indigofera-aspalathoides-shivanar-vembu-vahl.pdf
