Carbon Fibre As A Recent Material Use In Construction. Even today, we are constantly innovating, researching and developing technology in pursuit of a sustainable future. Throughout this evolution, researches and engineers have found themselves in constant search for new and better materials to optimally manage the performance cost tradeoff in the construction sector. Many new raw materials have been discovered and many ground-breaking composite have been developed, of which not all but some have proved to be a phenomenal success. Carbon fiber is one of these materials, which is usually used in combination with other materials to form a composite. The properties of carbon fiber, such as high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion makes them one of the most popular material in civil engineering possessing strength up to five times that of steel and being one-third its weight, Water management system/water plan • Water tank/rainwater tanks • Water saving shower heads • Dual-flush toilets. Waste Management • Encourage a reduction in paper usage by communicating electronically • After an initial period of technological development, aluminium alloys were used in many structural applications, including the civil engineering field. Aluminium is the second most widely specified metal in building after steel, and is used in all sectors from commercial building to domestic dwelling. This paper contains complete overview of use of aluminium in building construction. How it is beneficial in modern age building construction. This paper also contains the properties, advantages. Some question arises that whether aluminium is sustainable, fabricated for fast track, requires maintenance, are explained in detail in this paper. Through The Barriers To Sustainable Building Insights from Building Professionals on Government Initiatives to Promote Environmentally Sound Practices ABSTRACT 75% of the world’s energy is consumed in cities. 40% of the world’s energy is consumed in buildings. The most interesting potential for CO2-reduction in cities from an economical point of view lays in the modernization of the building’s infrastructure. Making existing and new buildings to Green Buildings is one of the most effective levers to meet the challenges of CO2 reduction in cities. The objective of the presentation is to give a short overview of the frame conditions, the existing labels and – most important – show success stories.

Bridges are the key elements in any road network Use of box girder is gaining popularity in bridge engineering fraternity because of its better stability, serviceability, economy, aesthetic appearance and structural efficiency. The structural behavior of box girder is complicated, which is difficult to analyze in its actual conditions by conventional methods. In present study a two lane simply supported Box Girder Bridge made up of prestressed concrete which is analysis for moving loads as per Indian Road Congress (IRC:6) recommendations, Prestressed Code (IS: 1343) and also as per IRC: 18 specifications. The analyzed of box girder using SAP 2000 14 Bridge Wizard and prestressed with parabolic tendons in which utilize full section. The various span/ depth ratio considered to get the proportioning depth at which stresses criteria and deflection criteria get satisfied. Keywords: Concrete Box Girder Bridge, Prestress Force, Eccentricity, Prestress Losses, Reinforcement, Flexure strength, shear strength, SAP Model. » Filed under Prestress Engineering.
