This document describes an experimental investigation into the strength and durability of concrete that uses fly ash and quarry dust as partial replacements for cement and sand. The investigation found that replacing cement with 20% fly ash and 50% of sand with quarry dust produced concrete with high strength comparable to conventional concrete. However, strength decreased as the replacement levels of fly ash and quarry dust increased from 30% to 50%. The study concluded that a blend of fly ash and quarry dust can be used to create concrete with sufficient strength while providing environmental and economic benefits over traditional concrete.

1. EXPERIMENTAL INVESTIGATION
OF STRENGTH AND
CHARACTERISTIC BY USING
FLY ASH AND QUARRY DUST
IN CONCRETE

2. AIM
• The main aim of our project is to determine and
compare the strength and durability properties of
using fly ash and quarry dust concrete with
conventional concrete.

3. ABSTRACT
• Due to rapid growth in construction activity,the
available sources of natural sand are getting
exhausted & also,good quality sand may have to be
transported from long distance,which adds to the cost
of construction
• Quarry dust is one such material which can be used
to replace sand as fine aggregate
• Cement replaced by fly ash with 20%,30%,40% and
50%
• Natural sand is replaced by quarry dust within partial
replacing

4. • By using these materials we have find out strength on
a concrete by adding partial replacement on cement
with fly ash and partial replacing of sand with quarry
dust
• The experimental studies are made to obtain the
properties of concrete like test are compressive
strength, spilt tensile strength and flexural strength

5. INTRODUCTION
• Concrete is the most commonly used construction
material; its usage by the communities across the
globe is second only to water
• The world wide demand for OPC would increase
further in the future. It is well-known that cement
production depletes significant amount of natural
resources and releases large volumes of carbon-
dioxide
• Most of the fly ash an quarry dust are considered as
waste and dumped in landfills

6. • In order to address the issues mentioned above, it is
essential that other forms of binders must be
developed to make concrete
• A comparatively good strength is expected when sand
is replaced partially with concrete admixtures
• The cement does not pollute the environment and so
it is eco-friendly

7. SCOPE
• To achieve a high strength concrete, compared with
conventional concrete
• To reduce the carbon-dioxide emission by the cement
industries but also utilize the waste material such as
fly ash and quarry dust
• To achieve a new type of concrete which is flexible
in nature

8. LITERATURE REVIEW
Effect of fly ash and quarry dust on properties
of concrete
‘K.LAKSHMIDEVI, A.V.NARASHIMA RAO’
• In this work an attempt is made to study the effect of concrete when
cement is replaced by fly ash at 5%,10%,20% and 30% by weight of
cement
• Sand replacement by quarry dust at 50% by weight of the sand for
M20 mix
• The partial replacement of cement by fly ash and sand by quarry
dust in concrete not only enhances the strength of concrete, but also
reduces the cost of production of concrete and at the same time, it
also eliminates the environmental pollution and hazards caused due
to the disposal of these waste by-products on land

9. Improved concrete properties using quarry dust as
replacement for natural sand
‘Anzar Hamid Mir’
• The reduction in the sources of natural sand and the requirement for
reduction in the cost of concrete production as resulted in the
increased need to find new alternatives materials to replace river
sand so that excess river erosion is prevented and high strength
concrete is obtained at lower cost
• One of the ways to improving sustainability is to reduce the human
consumption of natural resources

10. Experimental study on partial replacement of
cement with fly ash and complete replacement of
sand with M sand
‘T.Subramani, K.S.Ramesh’
• Therefore, it is necessary to replace natural sand in concrete by an
alternate material partially, without compromising the quality of
concrete
• Quarry sand is one such material which can be used to replace sand
us fine aggregate
• Compressive strength reduces when cement replaced fly ash.as fly
ash percentage increases compressive strength and split strength
decreases
