3. AIM
• The main aim of this project is to determine and analysis the
strength and durability properties of using manufactured sand
(M-sand) in GFRG panel.
• GFRG panel building system is rapid construction, cost
effective. It helps to save environmentally sensitive products
such as water, sand, and steel. These panels are too strong and
durable.
• M-sand helps to create large amounts of sand to a specific
quality. It doesn’t contain impurities such as silt and clay so
that it is stronger than river bed sand. It is produced from hard
granite stone by crushing. Manufactured sand is cheaper than
river bed sand (fine aggregate).
4. 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.
• M-sand is one such material which can be used to replace
sand as fine aggregate.
• Fine aggregate (natural sand) is replaced by m-sand with
20%,30%,40% and 50%.
• For hybrid construction process and Eco-friendly construction
GFRG is the best choice for builders. It is manufactured by
using gypsum as a core material, which is generated as by
product in the process of manufacturing fertilizers. By using
this materials, find out the strength on a concrete by adding
partial replacement of fine aggregate with M-sand.
• The investigations are made to obtain compressive strength,
split tensile strength and flexural strength of concrete.
5. INTRODUCTION
• Concrete is one of the fundamental materials in civil
engineering works especially in structural industries. This
purpose of this project is to experimentally investigate the
effect of partial replacement of fine aggregate as a
manufactured sand (M-sand) concrete in GFRG (Gypsum
Fiber Reinforced Glass) panel.
• In our project M-sand is partially used instead of fine
aggregate. Now-a-days natural river sand has become scarce
and costly. Hence we are forced to think of alternative
materials.
• Conventional concrete building takes more duration for
construction process that is why we had to find out the
alternative material that is called as GFRG ( Gypum Fiber
Reinforced Glass) panel.
6. SCOPE
• To achieve a high strength of concrete compared with
conventional concrete.
• To reduce the carbon-dioxide emission by the cement
industries but also reduce the smuggling of river sand.
• To achieve a new type of concrete this is flexible in nature.
• To reduce the duration and cost of construction process.
• It helps to save environmentally sensitive products such as
water, sand, brick and steel.
7. LITERATURE REVIEW
Effect of manufactured sand on compressive strength and
workability of concrete - ‘Nimitha Vijayaragavan’
• The main cause of concern is the non-renewable nature of
natural sand and the corresponding increasing demand of
construction industry.
• Therefore looking for an alternative to river sand has become a
necessity. The cheapest and easiest alternative to natural sand is
manufacturing sand by crushing rocks/stones in desired size and
grade by suitable method .Sand produced by such means is
known as manufactured/crusher/artificial sand.
• The results show that concrete with manufactured and natural
sand in varying proportions.
• The results show that concrete with manufactured sand shows
higher compressive strength where as workability decreased with
increasing proportion of manufactured sand.
8. Experimental research for compressive and flexural strength
of concrete can be improved by partial replacement of cement
by manufactured sand for natural fine aggregates
‘Shanmugapriya’
• It concluded from experimental researchers that compressive
and flexural strength of concrete can be improved by partial
replacement of cement by silica fume and manufactured sand
for natural fine aggregates, they suggested that optimum
replacement of natural sand by manufactured sand is 50%.
9. Experimental study of manufctured sand depend upon the
source of its raw materials
‘Shyamprakash’
• It says that manufactured sand satisfies the requirements fine
aggregates such as strength, gradation, shape angularity.
• It is also possible to produce manufactured sand falling into
the desired grade. They say that the mechanical properties of
manufactured sand depend upon the source of its raw material,
i.e. parent rock.
• Hence the selection of the quarry is very important to quality
fine aggregate

24. CAVITY FILLING IN GFRG PANEL
• Most common use of GFRG panels is as a
load bearing walls. Cavities of walls can be
unfilled or can be filled with concrete or
reinforced concrete depending on the load
coming on the panels.
• generally panels without filling might be
sufficient to carry loads up on two storeys.
• for additional floors, the wall panels have to
be strengthened with concrete infilling or with
reinforced concrete infilling depending on the
intensity of load acting on the panels.
• when load bearing multi storey building is
subjected to fairly high lateral load like
wind/earthquake in addition to gravity load like
dead load and live load, the panels will be
subjected to relatively high in plane bending in
addition to vertical load, such panels invariably
filled with reinforced concrete.
31. CONCLUSION
• The basic properties of materials are tested and results were
tabulated.
• The M-sand concrete is achieved by Cement, manufactured
sand, Coarse aggregate, Fine aggregate, super plasticizer and
water.
• The fresh concrete tests like slump flow tests were conducted
and the test result satisfies the standard values.
• The experimental investigation for mechanical properties like
compressive strength, split tensile strength and flexural strength
are carried out.
32. • The test result shows decreased values of mechanical properties.
• The bond strength of M-Sand is greater than normal concrete in
GFRG panel.
• In addition of 20% of M-sand we occur high strength of concrete.
• Whereas in 30%, 40% and 50% of M-sand there is low strength
comparing the conventional concrete strength.
• GFRG (Gypsum Fiber Reinforced Concrete) panel got required
strength at 20% of M-sand mix.
