3. Introduction
• Concrete is a composite material that contains water, aggregate and cement. The use
of concrete in the world is of order of 10 billion tones every year. Human consume no
material except water in such tremendous quantities. Concrete has some important
properties like compressive strength, workability, density, creep and permeability etc.
Concrete is strong in compression and week in tension. Major Portion in the concrete is
aggregate, it may be fine or coarse.
• Due to lacking in tensile strength, reinforcement bars are provided in concrete.
Concrete is very economic, low maintenance cost, weather resistant, fire resistant and
easily available that’s why used in pavements, water tanks, buildings and roads.
4. Cont.….
• Different form of the plastic are used now a days. Between 1950 and 2011, the
annual world production of plastics increased from 1.7 to 280 million tons.
• Plastic waste is dumped into the river or sea for disposal. It adversely disturb the
aquatic animals. Many countries reduces the use of plastic due to adverse
environmental pollution and most of the countries are in process of doing so.
• Use of plastic aggregate in concrete as a replacement of natural aggregate is growing
interest in construction industry, as it decrease the demand of natural aggregate.
5. Literature Review
Many researchers have carried out studies on plastic concrete in order to investigate the
behavior of plastic aggregate.
• Amiya Akram et al, (2015) worked on utilization of E-Plastic in concrete by partial
replacement as coarse aggregate. Total 24 samples were casted with 12 in phase-
1 and remaining 12 samples in phase 2. In phase-1, the first three casted cylinder
specimens were with control mix and the remaining were casted with 5% to
15%with 5% increment of E-Waste and 10% fly ash. The addition of 5% plastic
waste results in decreasing strength of concrete. The average reduction of
compressive strength for 15% addition of plastic waste is 35% without addition
fly ash. The split tensile strength gives better results when added E-waste is 10%.
However, further increment of E-waste results in decreasing split tensile strength.
The use of plastic aggregate in concrete increase the ductility of concrete and
reduce the self-weight of concrete mix.
6. Literature Review
• B.Harini & K.V.Ramana, (2015) worked on Use of Recycled Plastic Waste as
Partial Replacement for Fine Aggregate in Concrete. The strength properties of
M30 grade concrete were studied with different plastic percentage proportions.
The various plastic proportions are 5%,6%,8%,10%,15%,20% by volume. There
was decrease in compressive strength when the ratio of plastic to aggregate was
increased. The mix for which compressive strength was least and to that mix
partially replaced cement with silica fume of 5%,10%,15% by weight were added.
The strength properties were again studied, it was noticed that when cement was
partially replaced by 10%, 15% of silica fume was higher than reference mix
7. Literature Review
• Dr. Kiran Tajne and Pranita Bhandari, (2016) worked on the suitability of recycled
plastic as a coarse aggregate in concrete. Tests performed were density, specific
gravity and aggregates crushing value. The percentage substitution that gives higher
compressive and flexural strength was found in 10 and 15% NCA replaced concrete.
• Ahirwar et al. (2016) stated that the workability of concrete increases when the
percentage of E-Waste increases. The compressive strength of concrete decreased
with increase in percentage of E-Waste. It has been observed, when cement is
replaced by fly ash in concrete with E-Waste as a coarse aggregate, its compressive
strength is increased. Cement with 30% of fly ash replacement shows a better result.
8. Literature Review
Martina Záleská et al, (2018) replaced 50% of the natural aggregates with plastic waste
aggregates. The mechanical, thermal and chemical properties were compared with
control mix. The thermal conductivity of plastic concrete is seven time lower than the
normal concrete. Result shows that the mechanical properties decreases with increase
of percentage replacement of plastic aggregate and found satisfactory for non-bearing
structures. Plastic concrete is suitable for thermal insulation as well as plastic disposal.
K. Alagusan kareswari et al, (2016) worked on E-waste concrete. An experimental setup
was placed the specimens on the loading frame for two pointed loading conditions.
Determined the compressive strength, cube weight comparison, split tensile strength,
flexural strength. Self-weight of concrete reduces when there is rise in E-Waste
percentage. Hence it can be consumed as a light weight concrete. The yield of concrete
reduces when E-Waste was used as a replacement material for sand. It is coherent that
E-waste can be biased by using them as constructional material. The compressive
strength and split tensile strength of concrete pertaining to E-Waste aggregate is
progressively lesser in comparison with control mix concrete sample.
9. Problem Statement
• Rapid growth of technology, up gradation in latest innovation of electrical industry in
21st century has led one of fastest growing waste stream in world commonly known as
E waste .
• We generate about 40 million tons of E-waste every year and 30% of its part is made
of plastic around 1.2 million tons of plastic and on the other side due to wide use of
concrete as constructional element, accessibility of raw material is being questioned.
• The possible option is to use E-waste in form of coarse and fine aggregates in
concrete have environmental friendly use of the E-Waste.
10. Objectives
The major objectives and aim of this research work are:
• To investigate the effect on the strength of concrete by partial replacement of plastic
waste as filler (coarse and fine aggregate) material.
• Behavior and strengthening of plastic concrete.
• Effect of specimen geometry on strength of plastic concrete.
12. Methodology

13. Possible Outcomes
The research will be useful in the following aspects.
• This research will provide a platform to use plastic aggregates without compromising in
concrete strength.
• This research work will provide sufficient data for feasibility of plastic concrete for
structural member.
• From this study we will be able to utilize the E-waste as filler material to save the
natural source and its will give solution to environmental problem as well.
