The document is a report on a project to develop plastic bricks by mixing plastic waste with sand. It includes an abstract stating that tests found the plastic bricks have a compressive strength over 5 MPa, higher than clay bricks, and absorb only 1% water. An introduction explains that using plastic waste in brick making addresses waste management while enabling sustainable construction. A literature review summarizes previous studies on plastic brick properties. The objectives are to create a sustainable low-cost building material and evaluate its properties to ensure structural suitability.

3. ABSTRACT
Traditional clay bricks have been widely used in construction for centuries, but
their production process is associated with high energy consumption, carbon emissions,
and environmental degradation. In recent years, there has been increasing interest in
developing sustainable building materials that can reduce the environmental impact of
the construction industry. In this project, we have developed a new type of building
material by mixing plastic waste with sand to create plastic bricks. We conducted several
tests to evaluate the properties of the plastic bricks, including compressive strength, water
absorption, and resistance to temperature. Our results showed that the plastic bricks have
a compressive strength of 5 MPa, which is significantly higher than the average

Additionally, The plastic bricks have a water absorption rate of 1%, indicating that they
are highly resistant to water damage and moisture-related issues. The plastic bricks also
showed good resistance to temperature, with no significant changes in their properties
observed after being exposed to a temperature of 100 degrees Celsius for 10 hours. These
results suggest that plastic bricks have the potential to be a sustainable alternative to
traditional clay bricks, with lower environmental impact and higher durability.

5. INTRODUCTION
The utilization of plastic waste in manufacturing bricks is an innovative approach aimed at addressing
both plastic waste management and sustainable building materials. By incorporating shredded plastic waste
into the brick-making process, it helps reduce the environmental impact of plastic disposal and provides a
viable solution for eco-friendly construction. During the manufacturing process, plastic waste is mixed with
traditional building materials like clay or cement. The plastic acts as a binding agent, enhancing the bricks'
strength and durability while reducing the need for conventional resources. This method also reduces the
carbon footprint as fewer raw materials are required, and it can lead to cost savings in the construction
industry. However, it's essential to conduct thorough research and testing to ensure the quality and safety of
the resulting bricks. Properly executed, the utilization of plastic waste in brick-making can contribute
positively to the circular economy and foster sustainable practices in the construction sector.

1.“Fabrication and testing of Plastic sand bricks” by S S Chauhan, Bhusan
Kumar, Prem Shankar Singh, Abuzaid Khan, Hrithik Goyal, Shivank Goyal
(2019). They mixed the river sand and the PET plastic (molten form) in the ratio
of 1:2, 1:3, 1:4 for mould size of (230*100*75) mm for which they found
maximum compressive strength on the ratio of 1:2 mixture for the same size of
the bricks. The water absorption of these bricks was observed less than 5% that is
less than conventional clay bricks i.e. 15-20%.

2. “Utilization of plastic waste in manufacturing of plastic sand bricks.” By
Arvind Singhal, Dr. Om Prakash Netula (2018). They used the mixture of
plastic and stone dust in the molten form in the ratio of 3:7 in standard brick mould
for which stone dust was sieved through 4.75 mm using sieve analysis and
conducted test on water absorption to be found as 0%. Compressive strength of
plastic sand bricks is 5.6 N/mm2 at the compressive load of 96 KN.
3. “Plastic in Brick Application.” By Siti Nabilah Amir & Nur Zulaikha Yusof
(2018). The studies showed the possibility of using plastic as binder with the aid
of catalyst through depolymerisation of PET to replace cement. It was observed
that a significant decrease in compressive strength is observed for more than 50%
replacement of binder with PET waste. With increased amount of PET, the
softening point of the bricks produced was also increased. They used the different
size of moulds like (150*150*150) mm, (200*100*100) mm.

8. OBJECTIVES
• To explore the use of plastic waste as a raw material for building construction to reduce plastic waste and
promote sustainability.
• To create a low-cost building material using readily available materials that are easily accessible to
people in low-income communities.
• To evaluate the structural properties of the plastic brick to ensure it meets building code requirements and
is suitable for use in construction.
• To assess the environmental impact of producing plastic bricks and compare it to traditional building
materials.
