Abstract: In this study, sediment from louver edge process (LES) was used as a fine aggregate in autoclave aerated concrete (AAC) with various replacement levels (0%, 25%, 50%, 75%, and 100%) and pulverized fuel ash (PFA) was used to replace for ordinary Portland cement (OPC) at the level of 80% by weight. AAC samples were subjected to steam curing at 180C for 8 hours. The physical, mechanical and microstructure properties of AAC were examined. Results showed that the unit weight and compressive strength decreased with increasing the amount of LES. Scanning electron microscopy (SEM) reveals the presence of platy tobermorite in the reference sample but at increasing amount of LES, lath-like tobermorite and fibrous CSH were formedThis electronic document is a “live” template. The various components of your paper [title, text, heads, etc.] are already defined on the style sheet, as illustrated by the portions given in this document.

Abstract: n most of the metropolitan cities in India, the road use patterns are very different from those in developed countries. Globalization had brought in significant changes in lifestyles and occupation. Migration from rural to urban in search of better livelihood, increasing population, urbanization and modern infrastructures have made man more and more dependent on motorized vehicles. This resulted in the increase in economic activities and there has tremendous growth of motor vehicles which is considered as one of the primary factors responsible for increasing road accidents in many metropolitan cities of developing countries, including Hyderabad, India. In our country nearly 4.7 lakhs of lives are met with road accidents in the year 2008; a significant share of it is from the major cities. In this paper an assessment of the current level of road safety in Cyberabad city is done by utilizing the data obtained from secondary sources. Using severity data for Cyberabad City, a mixed logit m
