4. • Abstract
• From the very beginning of the nineteenth
century,it has been come to light that Fly Ash
may substitute cement in concrete industry.
• It may be mentioned here that Fly Ash
amounting to 15% to 25 % by mass has been
used as cementitious material in concrete.
• The compressive strength of concrete was
examined by replacing different proportions of
cement with Fly Ash.

5. Introduction about the Project
A various numbers of research have been
conducted to examine the effects of use of Fly
Ash as additive in cement, admixture in concrete
and as replacement of cement in concrete.
The compressive strength of concrete was
checked by replacing different proportions of
cement with suitable quantities of Fly Ash and
the results have been found most effective and
applicable
Incidentally most of the research works have

6. Objectives of the work
• Cement: Ordinary Portland cement (Ambuja
Cements of 53 grades) was used having
specific gravity: 3.10, 31.5% Consistency and
compressive strength 53 MPa
• Fly ash: From the combustion of pulverized
coal and transported by the flue gases of
boilers by pulverized coal, Fly Ash is produced.
It was obtained fromKolaghat thermal power
station, dried and subsequently used.
• Fine Aggregate: Natural sand with maximum

7. Status of the Project
Till Date :11/09/2022
• The concrete mix was designed for M25, M35
• and M50 grade and the mix design was done
as per IS 10262-1982 and IS 456-2000.
The properties of constituents of concrete was
taken into account for mix design of concrete.
Different concrete mixes with varying fly ash
content percentage were produced,
• replacing 0% (reference concrete), 15%, 25%,
35%,
• 45%, 55% and 65% cement in terms of weight.

8. Future Works and Overviews
Concrete is everywhere: in our bridges,
roads, buildings, work places and
neighborhoods. And underground,
concrete foundations support our
infrastructure.Here’s where the
importance of fly ash in concrete becomes
clear: More than 75% of all concrete is
made with fly ash. In some states, fly ash
is specified for all concrete structures. And
the concrete industry is only one of the
important entities using this abundant
waste material. after years endorsing its
positive contribution to the concrete
industry – as a hazardous waste. A
balanced discussion of the pros and cons
of recycling fly ash (aka coal ash or CCP)
in concrete from a global perspective is in
order. Let’s start with the source of the
massive amounts of fly ash: the world’s
electrical power industry (i).

9. Action Plan for Completion of Project
• By using fly ash the fastening of work at the
site
• The replacement of cement by fly ash can be
increases the strength of the concrete mix.
• Fly ash used as accelerator
• Mainly used as admixture
