Abstract

There is a growing interest towards quantifying the direct and indirect emission of carbon (embodied energy) in the production and utilization of new types of concrete. Advanced technological development of concrete and demand for high strength and high performance construction materials have lead to the evolution of Ultra High Performance Concrete (UHPC). This material is primarily characterized with high strength and durability and when reinforced with steel fibers or steel tubes exhibits high ductility. Existing UHPC preparation methods involve costly materials and classy technology. This
may increase the embodied energy of UHPC, which is not in favor of green environment for a sustainable technology and Embodied energy is the energy required to produce any goods or services, which is incorporated or embodied in the product itself. Embodied energy assessment aims in finding the sum of total energy necessary for an entire product life-cycle. To make UHPC an eco-friendly material, the embodied energy involved in its production should be reduced by the application of simple technology. Many research works are being done in replacing certain amount of cement with silica fume (SF), fly ash (FA), ground granulated blast furnace slag (GGBS) etc. in order to achieve an environmental friendly UHPC of high strength of more than 150 MPa and an elevated level of durability. This study is focused on the assessment of embodied energy involved in the production of UHPC with alternate cementitious material. With the knowledge of embodied energy for UHPC, implications can be deliberated by varying the constituents and replacing cement with certain amount of eco-friendly materials, so as to reduce the environmental impact of construction with UHPC.
