“…Two other previously reported observations support the linearity of corrosion after initiation. Firstly, linear behaviour was also observed in short term exposure tests of model concrete sewers in controlled laboratory and pilot scale experiments [3,37,38]. Secondly, there are data from field experiments conducted on actual concrete sewers near Melbourne, Australia [39] that show linear behaviour for exposures up to 18 years, under moderately aggressive conditions (H 2 S concentrations ranging from 5 to 40 ppm, Fig.…”

“…50% reduction in the service life of concrete truck sewers were reported in their findings indicating various deterioration due to the biogenic corrosion of concrete. In recent years, various researchers have explored developing prediction models for the concrete pipe wall reduction rate and service life span [26][27][28] by considering factors that influence MICC. New findings however still require implementation in concrete pipe standards so that innovative improvements can be introduced in full scale RCP production.…”

Reinforced concrete pipe (RCP) standard guidelines and industry practice have rather been disconnected from the end-users' expectations. No genuine effort has so far been made to create synergy between the expertise gained and advances made around the world. With the advent of strong competition from flexible pipe products and changing end-user expectations, a critical look at the current state-of-the-art is needed. In the present paper, RCP standards from a study area representing a quarter of the world's population (Canada, United States, United Kingdom, China, Australia and New Zealand) were critically analyzed. Comparisons were made in terms of product and material requirements, structural load testing, hydrostatic performance, and durability requirements. It is shown that the RCP sector lags modern developments in concrete technology, standard code advances and materials innovations. The analysis also revealed various knowledge gaps in terms of the mechanical, hydrostatic and durability performance of RCP. Recommendations emanating from this critical analysis aim at tailoring performance-based guidelines that can better capture current market needs and user expectations.

“…Morphological characteristics of colonies such as size, colour, surface, and colony boundary (Holt et al, 1994) were determined. Also, physiological characteristics such as sulphate concentration, pH/Eh, cellular growth, source of energy, aerobic/anaerobic, and temperature were measured (Bielefeldt et al, 2009). Confirmed SOB colonies were transferred to -20°C for DNA extraction and subsequent applications.…”

Abstract. Sulphur-oxidizing bacteria (SOB) are one of the most important metabolic types of bacteria living in very different soil environments. Mine environments with high concentrations of metals and extreme conditions have led to habitat-specific genera and operational taxonomic units (OTUs) of bacteria. In this study, we compared the diversity of SOB and non-SOB at the Sarcheshmeh Copper Mine Complex (Iran) with the surrounding agricultural soil. Thirty-six mine and agricultural sites were sampled aseptically and assessed by culture-dependent (full-length 16S rRNA cloning) and independent (Denaturing Gradient Gel Electrophoresis (DGGE)) approaches. Results indicated that soil samples from the copper mine region contained diverse OTUs affiliated with of SOB genera including Acidithiobacillus sp. and Sulfobacillus sp. and non-SOB including Pseudomonas sp., Bacillus sp., Sphingobium sp., Sphingomonas sp., Acinetobacter sp., Halospirulina sp., and Propionibacterium sp. In addition, the soil samples from the surrounding agricultural sites contained representatives of SOB genera as Thiobacillus sp., Starkeya sp. and non-SOB as Pseudomonas sp., Acinetobacter sp., Bacillus sp., Sphingobium sp., Streptomyces sp., and Propionibacterium sp. These bacterial communities were significantly affected by sulphur in the mine area, and by pH and calcium concentrations in the agricultural soils.
