Experimental Investigation on Elastic Properties of Concrete Incorporating GGBFS
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Concrete is the most widely used man made construction material in the construction field all over the world. Concrete is made up of fine aggregates, coarse aggregate, cement and water for hydration of cement. Fine aggregates and coarse aggregates acts as filler material and cement acts as binding agent in concrete. In concrete cement plays a very important role in gaining strength but the major problem by the production of cement is liberation of large amount of CO2 (green-house gasses) which is very dangerous to the environment. According to many researchers, the best way to overcome this problem is to use optimum amount of cement and its maximum replacement by pozzolana or cementitious materials such as fly ash, GGBFS (Ground granulated blast furnace slag), metakaolin etc. In the present work GGBFS is used as replacement material. The optimum replacement of GGBFS with cement is characterized by high compressive strength, low heat of hydration, resistance to chemical attack, better workability, good durability and cost-effectiveness. Also, an attempt has been made in predicting the elastic properties of GGBFS concrete as per various design standards and new relationships has been proposed.
