Estimation of Life Cycle Cost of RC Infrastructure Using Different Analysis Methods
Abstract: Accuracy of service life prediction largely influence life cycle cost of infrastructure. Recent research come up with the conclusion that ingression of chloride to cover concrete is dependent on the water penetration front which dramatically change the service life. Therefore, in this study chloride ion profiles and behavior of penetrating water for slag concrete with w/c ratio as 40%, 55% and 70%, respectively, cast in laboratory, were examined. Furthermore, life …

Method of Analysis for Chloride Distribution in Concrete from Torrent Data
Abstract: Design w/c ratio becomes less important than achieved cover performance in the case of existing structure. Therefore, inspection data of chloride profile from some real structures do not always obey the rule of Fick’s law, suggesting the influence of a new parameter. In this study, chloride ion profiles and behavior of penetrating water for normal, fly ash and slag concrete with w/c ratio as 40, 55, and 70%, respectively, cast …

Influence of Liquid Paraffin Wax as an Internal Curing Agent for Concrete Mixes
Abstract: Curing is the most crucial measure for the compressive strength of concrete. In this study an internal curing agent named as paraffin wax which comes under a brand name cure concrete has been used to check its efficacy. Cure concrete has a harder surface and is more impervious. Preventing moisture loss is essential for avoiding plastic shrinkage, which lowers permeability and contributes to the formation of strength. Furthermore, to increase …

Renovation, Modernisation and Uprating of Hydropower Station
Abstract: Although hydropower has been used since ancient times to grind floor and to perform other tasks, the world’s first hydro electrical power generation started in England in 1881. Hydropower facilities now generate nearly a quarter of the world's electricity. Hydropower is produced in more than 150 nations throughout the world. Hydropower has many advantages over other conventional sources of power and so it is the main attractive source for developers. …
