3. Concept
• To make the high strength plastic sand bricks
• Reuse the waste plastic
• To clean the environment
• To reduce the economical problems
• To reduce the amount of waste plastic for land
filling

4. Introduction
• The waste plastics are to be effectively utilised.
• The plastic waste is naturally available in adequate quantity .
• This is one of the best ways to avoid the accumulation of plastic waste
which is an on-degradable pollutant.
• The Environmental Protection Agency reports plastic made up 12% of
the 254 million tons of waste generated in 2007. That’s more than 30
million tons of plastic in one year. Some reports state plastic materials
can take hundreds of years to break down in a landfill.
• So If we put this waste plastic in bricks, it can give various advantages

5. Objective of study
• To compare strength of Bricks casted with mixture of liquid form
of waste plastic and natural soil to Burnt bricks and fly ash
bricks.
• To vary the percentage of plastic in bricks to determine the
strength performance.
• Cost comparison in between bricks casted with mixture of liquid
form of waste plastic and natural soil to Burnt bricks and fly ash
bricks.
• To determine the optimum percentage of plastic and sand in
bricks.
• To compare water absorption value of Bricks casted with mixture
of liquid form of waste plastic and natural soil to Burnt bricks
and fly ash bricks.

6. Need of present study
• Plastic pollution involves the accumulation of plastic
products in the environment that adversely affects
wildlife, wildlife habitat, or humans.
• The prominence of plastic pollution is correlated with
plastics being inexpensive and durable, which lends to
high levels of plastics used by humans.
• it is slow to degrade.
• more than 5 million tonnes of plastic are consumed each
year, of which an estimated mere 24% makes it into
recycling systems. That leaves a remaining 3.8 million
tonnes of waste, destined for landfills.

8. Methodology
• The main objective of this research work is to develop an
efficient way to effectively utilize the waste plastic which
is a great threat for the sustainment of ecological balance,
With the laterite quarry waste to manufacture an
alternative building material by which both the questions
of a scientific disposal of waste plastic as well as scarcity of
traditional building materials can be answered.

9. Materials
Waste plastic
• By definition the plastics can be made to different shapes when
they are heated.in closest environment it exists in the different
forms such as cups, furniture’s, basins, plastic bags, food and
drinking containers, and they are become waste material
• Accumulation of such wastes can result into hazardous effects to
both human and plant life.
• If they are not recycled then they will become big pollutant to the
environment as they not decompose easily and also not allow the
water to percolate in to the soil and they are also poisonous

10. River Sand
• Sand is naturally occurring granular material which is composed of
mineral particles and finely divided material
• The composition of sand varies depending on the local rock conditions
and sources, but the most constituent of sand in inland continental
settings and non-tropical coastal region is silica dioxide (Sio2) in the
form of quartz.
• Sand are now used in all the construction process.

11. Manufacturing
• In first step we should collect the waste plastic bags and bottles.
• Next the collected waste bags are cleaned with water and dried to remove
the water present in it after this the plastics are burned out by using
stones and firewood. The stones are arranged to hold the drum and the
firewood is placed in the gap between the stones and it is ignited.
• The drum is placed over the above setup and it is heated to remove the
moisture present in it.
• Then the plastic bags are added to the drum one by one and the river
sand is added to the plastic when it turns into hot liquid.
• The sand is added is mixed thoroughly using rod and trowel before it
hardens. The mixture has a very short setting hence mixing process must
not consume more time on the other hand the process should be
complete.
• These mixtures is then poured in to the brick mould and they are
compacted using steel rod and surface is finished using trowel. Before
placing the mixture into the mould, the sides of the mould are oiled to
easy removal of bricks

15. Advantages And Limitations
ADVANTAGES:-
• It should be economical
• It should be durable
• It should be light weight
• It should be fire resistance
• It should be easily available in nature
• It should less water absorption compare to burnt brick or fly ash bricks
• It should be easily made
• It should be good strength
• Removal waste plastic

16. DISADVANTAGES:-
• Take proper safety precautions for melting plastic
• Mould requirement is more
• To produce smoke while making bricks
• Generate high heat while making bricks
Disadvantages

17. • The Plastic sand bricks possess more advantages which include
Cost efficiency, Removal of waste products thus abolishing the land
requirement problem for dumping plastic, Reduction in the
emission of greenhouse gases by the conversion of flue gases into
synthetic oil etc.,
• This method is suitable for the countries which has the difficult to
dispose /recycle the plastic waste.
• The natural resources consumed for the manufacturing of Plastic
sand bricks are very much less when compared to its counterparts.
• The manufacturing cost could be reduced further by replacing the
river sand with fly ash/quarry dust or other waste products.
• Owing to the numerous advantages further research would improve
the quality and durability of plastic sand bricks and flyash brick.
