AN EXPERIMENTAL STUDY ON PARTIAL REPLACEMENT OF CEMENT WITH GGBFS AND FINE AGGREGATE WITH BFS IN CONCRETE CONTAINS USING GLASS FIBER

Abstract

The increasing popularity of concrete as a construction material is placing a huge burden on the natural
sand reserves of all countries. In view of the environmental problems faced today considering the fast reduction of
natural resources like sand and crushed granite aggregate, engineers have become aware to extend the practice of
partially replacing fine aggregate with waste materials. GGBFS is used to make durable concrete structures in
combination with ordinary Portland cement. In this present study Ground Granulated blast furnace slag were replaced
with Cement and the properties of concrete were studied. Blast furnace slag is a by-product from blast furnaces which is
used to produce iron. Blast furnace slag has been used extensively as a successful replacement material for Portland
cement in concrete materials to improve durability, produce high strength and high performance concrete, and brings
environmental and economic benefits together, such as resource conservation and energy savings. In this study attempt
made by the two Materials are replacing with Fine aggregate and Cement with Ground Granulated blast furnace slag
and Blast furnace slag with addition of the glass fiber. This study is focuses on the mechanical properties of concrete
incorporating mixture with partial replacement of cement by GGBFS and Fine Aggregate by BFS. Twenty mixes were
containing cement replacement by GGBFS as 0 to 40%, Fine Aggregate Replacement by BFS as 0 to 40% and mixture of
Glass fiber 0.4%, 0.5% by volume for M30 grade of concrete. The durability test is focus on same as above replacement
and fiber content for M30 grade of concrete. The mechanical properties investigated in current study include
compressive strength, splitting tensile strength, durability test.
