Sustainable Construction Using Autoclaved Aerated Concrete (Aircrete)Blocks by Ash Ahmed in Research & Development in Material Science Low Density Aircrete (Density≤450kg/m 3 , compressive strength≤3N/mm 2 ) has been used extensively for the construction of dwellings in many parts of Europe. In the UK, however, lack of availability has restricted the use of Low Density Aircrete. Developments in Eurocode 6 require adjustment to the UK design procedures, allowing greater utilization of Low Density High Performance Aircrete. The material has considerable advantages, which include its economical, mechanical and physical properties. It is usually manufactured using pulverized fuel ash, which is an industrial by-product. The potential for using Low Density Aircrete for the UK and indeed global construction industry is therefore highly promising with substantial economic and environmental benefits. Furthermore, calculations show the thermal insulating (shielding for hot climates) ...

Thermal Analysis of Oil Pipeline Coatings-Crimson Publishers

Thermal Analysis of Oil Pipeline Coatings by Mumtaz Mirza M in Research & Development in Material Science The research paper focuses on oil pipe lines used in desert region of Oman that is exposed to very high ambient temperature affects the coating properties resulted in brittleness in coatings. The impact of high ambient temperature is analyzed through heat transfer rate and thermal stress. Two coatings are considered, commercially available fusion bonded epoxy (FBE) coating and experimentally developed electroless nickel phosphorous (EN-P) composite alloy coating. Simulation is done under three ambient conditions, morning at 308K, mid-day at 328K and evening when temperature was around 313K along with crude oil temperature of 343K. Thermal analysis demonstrates that at high ambient temperature EN-P composite alloy coating has low heat transfer rate as compared to FBE coating and its thermal efficiency was around 96% against uncoated pipe and around 69.4% less as compare...
