 INTRODUCTION
• Concrete is a composite material composed mainly of Coarse aggregate, Fine aggregate, Cement and Water. It is an
indispensable material of today’s construction world has gone through stages of development. The sustainable
development in construction involves the use of waste materials and by-products.
• GGBS is obtained by quenching molten iron slag (a by-product of iron and steel making) from blast furnace in
water or steam, to produce a glassy, granular product that is then dried and ground into fine powder.

• Granite powder waste is a waste material that results from the processing of granite rocks.
• Granite powder is a promising material for use in concrete, similar to pozzolanic materials. The highly dispersible
mineral component fills the space between grains and forms a rigid structure, improving the density and
rheological properties of cement paste

 OBJECTIVES
• To Study the various Physical and Chemical properties of Ground granulated blast furnace slag (GGBS) and Granite
powder used for partial cement replacement.
• To Study the workability properties of concrete when cement is partially replaced with GGBS and Granite powder in
concrete.

• To Study the various mechanical properties, such as Compressive, Split tensile and Flexural strength properties of
concrete.

• To determine the most optimized mix of GGBS and Granite powder.

 SCOPE
• As concrete is made with Industrial waste and by-products, it does take more time to come in India
because Industries are having problem in disposing the waste. It is having reduced Environmental impact
with reduction in carbon dioxide emission.
• For economical and ecological benefits, the utilization of GGBS in concrete enhances its workability, and
it reduces heat evolution and durability. It is more resistance to corrosion of reinforcement.
• Granite powder can be used in cement as a partial replacement for cement itself, since it is acting as a
pozzolanic material that enhances the strength and durability of concrete by filling voids and reacting with
the free lime in the cement paste, leading to improved compressive strength, reduced porosity, and better
water resistance.

 RESEARCH PROPOSAL
• The Concrete will be designed for M 30 as per Indian Standard code 10262-2019.
• Physical properties test for Coarse aggregate, Fine aggregate and OPC 53 grade cement will be performed.
• To make the concrete more workable for effective consolidation and placing without any need of extra
workmanship, it is proposed to use Poly carboxylate ether - high range water reducer Superplasticizer.
• Literature studies has revealed that this high range water reducer is compatible with green concrete ingredients.
• The optimal dosage of the Super plasticizer will lower down the w/c ratio and accordingly increase the various
strengths which will be evaluated.
• Fresh concrete properties test such as Slump, Flow table and Compaction Factor test will be performed in
laboratory.
• Hardened Concrete properties test such as Compression , Split tensile and Flexural strength test will be performed
for 7 days, 14 days and 28 days.
