Approximately 10 billion kilograms of plastic waste are produced exclusively in The United States every year.
It accounts for roughly 7% of total waste produced by mass.
Plastic is responsible for 30% of total waste produced by volume.
Plastics need much more energy to recycle than paper, glass or metals.
Incorporate plastic as recycled element in building material
Brainstorming
Material needs to be versatile
In composition & Application
Concrete
Offers Flexibility
Mix & Design
It is the most commonly
used material Worldwide

PET BOTTLES
CONCRETE
Demonstrate that an optimal plastic content can be achieved in a concrete mix.
INTENTIONS OF THE EXPERIMENT
Hold characteristics that make for viable structural concrete member.
It can capitalize effectively on the presence of plastic aggregate.
CONCRETE WITH PLASTIC AGGREGATE
CONCRETE
CHARACTERISTICS
Designed to achieve a balance between economy & strength, placeability, durability, density, and appearance.
Aggregates occupy appr. 75% of total volume of concrete mix.
Fine Aggregates (approx. 5 millimeters)
Course Aggregates (larger than 5 millimeters)
(ACI 3.3.2)
It's expected Plastic Concrete strength will be less due to the "joint factors".

TESTING
CYLINDER
CYLINDER
TESTING
The concrete cylinders were tested at different plastic aggregate mix percentage of 0,5,10,15
Tests were made at the 14th day and 28th day after mix was prepared.
Concrete was tested for compression and tension
DATA
COLLECTION
(ACI 211.1)
The plastic used in this experiment is a post-consumer recycled PET pellet, with an approximate radius of a tenth of an inch ( about 2.5 millimeters)
Thank you
ANY
Plastic Pellets
The tensile strength of concrete is relatively low, about 10 to 15% of the compressive, occasionally
20%
The Tension Strength is of interest in designing of highway and airfield slabs as shear strength and Resistance to cracking are very important to sustain such loading.
