STRENGTH PROPERTIES OF CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT AND SAND WITH GRANITE SLUDGE & GGBS

Abstract

Now a day’s high strength and high performance concrete are being widely used all over the world. Most
applications of high strength concrete have been in high rise buildings, long span bridges and in some special applications in
structures. Traditionally, the basic ingredients of concrete include Cement, Fine aggregate and Coarse aggregate. In
general, Ordinary Portland cement is utilized in the creation of civil structures. This OPC can be replaced by Granite Sludge
and costs lower than OPC. Similarly, another important ingredient of concrete is Fine aggregate i.e., river sand which is a
highly scarce resource. To meet the growing applications for the river sand, Ground Granulated Blast furnace Slag (GGBS)
which is readily available that can be utilized in the construction activity. The present investigation deals with the
development of concrete when the cement and river sand are replaced by Granite Sludge and GGBS in various proportions.
This study mainly focuses on the discussion of strength and workability characteristics of concrete, when the cement is
replaced by Granite Sludge partially in various proportions, together with the replacement of river sand by GGBS in various
proportions. Cubes are casted for each proportion and tests are conducted for obtaining the compressive strength of
concrete. The obtained results are discussed and finally conclusions are made accordingly.
