Flood Resistant Houses
Abstract: Unusual high stage of river is called flood. In flood, the water level rises to an extent in which water starts spilling over the bank and spreading to the flood plains. The frequency and intensity of floods has intensified in the country over the years primarily due to encroachment of flood plains because of obvious advantages of water supply and irrigation. Flood causes extensive damage to infrastructure, the economy and …

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. …

Using digital holographic interferometry to monitor symmetrical temperature fields in liquids and an interference technique for simultaneous heat and mass transfer
Abstract: In this work, we offer a technique for off-axis digital holographic interferometry to measure dynamic temperature change quantitatively in real-time and visualise volumetric temperature fields formed by a 2D axial-symmetric heated fluid from a pulsatile jet in a water tank. For the experimental examination, a portable Mach-Zehnder interferometer was constructed. The pulsatile jet was supplied with hotter water and submerged in a tank of water. Results that have been averaged, …

Development of a Mathematical Model for Assessment of Total Dissolved Salts
Abstract: The main purpose of this research is deriving a new equation which can be used to find the total dissolved salts (TDS) in the soil. This equation enables us to find the total dissolved salts (TDS) by finding density of the saline solution resulting from dissolving the soil in distilled water. This equation shows very good results. So, in this research a new method was proposed to find the total …

Stabilization of Alluvial Soil by using Boiler Feed Ash
Abstract: The feasibility of using industrial wastes, boiler feed ash (BFA) (rice husk-based) from an oil mill for soil stabilization was studied. The waste material is produced as an industrial by-product in the boiler of the oil mill; the waste contains silica compound up to 85%, hence it can be used as a stabilizing agent. The effects of adding BFA on Proctor's density, Atterberg’s limits, soil plasticity and the CBR value …

Economic Importance of Laterite Deposit in Oke-Oyi Area, Ilorin, Nigeria
Abstract: Two soil samples A and B were taken from Oke-Oyi, Kwara state, North Central, Nigeria. The water content of the samples are 5.8% and 6.5 for sample A and B respectively. This shows the variability in water table in the area. The specific gravities values are 2.7 and 2.78 for samples A and B, this is an indicator of inorganic soil. Grain size analysis show the laterite to be sandy …

Ground Protection from Rain Using PIC Microcontroller
Abstract: AbstractIn this paper, the author has designed a system which senses the rain water through sensor. The system uses rain water sensor, transformer, controlling card, buzzer, relays, two movable flaps and LED. The moment it starts raining, the buzzer turns ON automatically, the ground is covered, and lights will also switch ON. As soon as the rain stops, the switch is pressed for uncovering the ground. Technological enhancement enrich the …

A New Description of Multi-phase Flow Behavior at Boundary Layers of Low-permeability Porous Media
Abstract: At present, the recovery factor of low permeability oilfield in China is only about 20%, which is enormously lower than the recovery factor index of 60% by using water-chemical flooding in medium and high permeability layer. There are a lot of causes that resulted in low recovery factor, among them that the complex pore structure, tiny throat, large pore throat ratio and non-Darcy flow in low-permeability oil layer are the …
