“STUDY ON PARTIAL REPLACEMENT OF CEMENT WITH IRON ORE MINE TAILING AND GROUND GRANULATED BLAST FURNACE SLAG”

Abstract

In this research the study of compressive strength and flexural strength of concrete as partial replacement
of cement by Iron ore tailing and Ground Granulated blast furnace slag is carried out. The study is done by replacing
cement (by weight) individually by Iron ore tailing 0%, 5%, 10%, 15% for , individually Ground granulated blast
furnace slag 0%, 5%, 10%, 15% and together by both Iron ore & Ground granulated blast furnace slag for 0%, 5%,
10%, 15% for M-25 grade. For Compressive strength test 120 cubes were casted of size 150mm x 150mm x 150mm for
7,14, 21 and 28 days. For flexural strength test 30 beams were casted of size 150mm x 150mm x 700mm for 28 days.
The test for compressive strength and flexural strength has been done and results are shown in graph. Graphs are plotted
between flexural strength and compressive strength and percentages of IOT & GGBFS.
This research has shown that the IOT and GGBFS have the potential to produce high strength concrete at reasonable
cost. As the graphs showing increasing slope indicating strength is achieved by replacing cement by IOT & GGBFS at
different percentages.
