ENGINEERING PROPERTIES OF STRUCTURAL
LIGHTWEIGHT CONCRETE



INTRODUCTION

Structural lightweight aggregate concrete is an important and versatile material in modern
construction. It has many and varied applications including multistory building frames and
floors, bridges, offshore oil platforms, and prestressed or precast elements of all types. Many
architects, engineers, and contractors recognize the inherent economies and advantages
offered by this material, as evidenced by the many impressive lightwei ....etc

Silicon on insulator technology (SOI) refers to the use of a layered silicon-insulator-silicon substrate in place of conventional silicon substrates in semiconductor manufacturing, especially microelectronics, to reduce parasitic device capacitance and thereby improving performance SOI-based devices differ from conventional silicon-built devices in that the silicon junction is above an electrical insulator, typically silicon dioxide or (less commonly) sapphire. The choice of insulator depends largely on intended application, with sapphire being ....etc

MECHANICAL PROPERTIES OF CONCRETE INCORPORATING USED
FOUNDRY SAND
ABSTRACT
Metal foundries use large amounts of the metal casting process. Foundries successfully
recycle and reuse the sand many times in a foundry and the remaining sand that is termed
as foundry sand is removed from foundry. This study presents the information about the
civil engineering applications of foundry sand, which is technically sound and is
environmentally safe. Use of foundry sand in various ....etc

Measurement and simulation of the electric field of high voltage
suspension insulators

Vassiliki T. Kontargyri, Ioannis F. Gonos*,y and Ioannis A. Stathopulos



INTRODUCTION
The insulator strings, which are used for the suspension of overhead transmission lines, constitute one of the most important parts of
the transmission lines as they used to give support to electrical conductors and shield them from ground or other conductors as well
as they provide the necessary mechanical suppo ....etc

ABSTRACT
This paper provides an introduction to silicon-on-insulator (SOI) technology and the operating principles of high-voltage SOI devices, reviews the performance of the available SOI switching devices in comparison with standard silicon devices, discusses the reasoning behind the use of SOI technology in power applications and covers the most advanced novel power SOI devices proposed to date. The impact of SOI technology on power integrated circuits (PICs) and the problems associated with the integration of high-voltag ....etc

Abstract
This paper focuses on the experimental investigation carried out on high strength concrete reinforced with hybrid fibres (combination
of hooked steel and a non-metallic fibre) up to a volume fraction of 0.5%. The mechanical properties, namely, compressive strength, split
tensile strength, flexural strength and flexural toughness were studied for concrete prepared using different hybrid fibre combinations –
steel–polypropylene, steel–polyester and steel–glass. The flexural properties were studied using four point ben ....etc
