Solid waste management is among the key environmental issues in India. The current research applies to the usage of or even recycled plastics as an alternative for rough aggregates in concrete. The primary goal of the analysis is to investigate the modification in the physical attributes of concrete by the inclusion of plastics to concrete. In addition to the physical qualities, winter qualities of the ensuing concrete may also be analyzed. The utilization of plastic aggregates was discovered to lead to the development of sturdy concrete. Additionally, with the plastics, the tensile and compressive strength of the concrete reduces. The foremost change brought approximately by using plastics is the fact that concrete's thermal conductivity is decreased due to the utilization of plastics. It is able to thus be declared recycled plastics are usually utilized for thermal insulation of structures. Series of experiments had been performed in this current study for a comparison of the usage of Used Plastic as a replacement of sand in various different proportions. The main conclusions drawn was that the compressive strength increases with the inclusion of Used Plastic upto a certain proportions and then reduces the strength.

This document summarizes research on using waste plastic to partially replace aggregates in concrete. Experiments found that plastic concrete has lower compressive and tensile strength than traditional concrete. However, plastic concrete has better thermal insulation properties due to plastic's lower thermal conductivity. Tests also showed that concrete workability, as measured by slump and compaction factor, decreases with higher plastic replacement ratios but mixtures remain workable. The conclusion is that plastics can be used to produce lighter weight concrete for some applications while providing environmental benefits of waste reduction.

Properties of Concrete using Plastic Scrap a Review
The plain cement concrete has very low tensile strength, restricted pliability, and little protection from breaking. Inward miniaturized scale breaks are innately present in the concrete and its poor rigidity is because of the proliferation of such small cracks, in the long run prompting fragile disappointment of the concrete. The most generally acknowledged solution for this flexural shortcoming of cement is the regular fortification with high quality steel. Regardless of the way that these procedures offer flexibility to people, they however dont grow the trademark unbending nature of solid itself. In like manner the help putting and profitable compaction of RCC is amazingly troublesome if the solid is of low workability especially by virtue of overpowering solid M 30 . In plain concrete and near feeble materials, assistant parts scaled down scale breaks become even before stacking, particularly on account of drying shrinkage or distinctive purposes behind volume change. The width of these breaks on occasion outperforms a few microns, yet their two estimations may be of higher enormity.

IRJET- Comparision of Mud Brick, Sand Mud Brick and Plastic Sand Mud Brick
This document compares mud bricks, sand mud bricks, and plastic sand bricks. It summarizes research that produced plastic sand bricks by melting plastic waste and mixing it with sand at percentages of 5%, 10%, and 15%. The plastic sand bricks were then tested for compressive strength and water absorption. Testing found that compressive strength increased with higher percentages of plastic, and could potentially be further increased with the addition of super plasticizers. Producing plastic sand bricks in this way helps address the problem of plastic waste disposal while utilizing plastic as a construction material.
Study of Flexural Strength and Flexural Modulus of Reinforced Concrete Beams ...
This study was carried out to investigate the effects of raffia palm fibre on some mechanical behaviour (flexural strength, flexural modulus, water absorption rate and density) of concrete. A concrete mix ratio of 1:2:4 was used for the concrete beams production, while a water to cement ratio (w/c) of 0.5 was adopted. In the study, three different fibre lengths (10, 20 and 30 mm) and three different fibre content (volume) by mass of fine aggregate (1, 2 and 3%) were considered. According to the results of the preliminary test carried out on the fine aggregate, it had a silt content of 1.6%, a moisture content of 8.3%, and a specific gravity of 2.95. Flexural properties of the beams were tested in accordance with ASTM recommended procedures after 28 curing days. Results obtained showed that fibre volume had significant (p ≤0.05) effect on the flexural strength and flexural modulus of the beams. The flexural strength and flexural modulus decreased linearly as the fibre volume increased from 0% to 3%. According to the results, the fibre reinforced beams were more ductile, when compared to the unreinforced concrete beams. In addition, the densities of the beams decreased with increase in the fibre volume; while their water absorption rate increased with increase in the fibre volume. The low densities and brittleness of the reinforced beams (at low volume) made them good building materials, especially when heavy weight beams are a problem, provided the beams are not exposed to high moisture levels.

Mechanical Characterization of Biodegradable Linen Fiber Composites
Abstract: The conventional materials like iron, mild steel, cast iron etc are having good mechanical properties. Hence they are widely used in structural engineering applications. These conventional materials have some defects like formation of rust, low weight to strength ratio, high production cost. To overcome these defects, engineers started fabricating composite materials. Composites exhibit peculiar properties like different strengths in different directions, rust resistant, high strength to weight ratio, but they pollute the environment. Now the natural fibre composites are widely used in automobile industry. The natural fibres and resins are used to fabricate an eco friendly composite material. Lack of resources and increasing environmental pollution has evoked great interest in the research of materials that are
friendly to our health and environment. Bio polymer composites fabricated from natural fibres is currently
the most promising area in polymer sciences. This is designed to assess the possibility of fibre as reinforcing material in composites. Epoxy resin was made a stiffened panel to conduct tensile test. In this paper it is aimed to explain all possible ways to use natural composites in automobile components. The main advantages of using natural fibers are their degradability and light weight. They are environment friendly and also increase the fuel economy

concrete mix and the optimum modifier content was found. Cubes and Cylinders were casted and tested for 28 days strength.
These tests revealed that by adding Waste plastics and rubber as a partial replacement in Fine Aggregate and Coarse
aggregate by volume, the strength of concrete decreased. The cube strength decreased as the percentage replacement increased
due to their poor binding properties. By using Plastic waste and Waste Tyre Rubber as modifier, we can reduce the quantity of
coarse aggregate and fine aggregate by their volume, hence decreasing the overall cost of construction

Mechanical Characterization of Biodegradable Linen Fiber Composites
Abstract: The conventional materials like iron, mild steel, cast iron etc are having good mechanical properties. Hence they are widely used in structural engineering applications. These conventional materials have some defects like formation of rust, low weight to strength ratio, high production cost. To overcome these defects, engineers started fabricating composite materials. Composites exhibit peculiar properties like different strengths in different directions, rust resistant, high strength to weight ratio, but they pollute the environment. Now the natural fibre composites are widely used in automobile industry. The natural fibres and resins are used to fabricate an eco friendly composite material. Lack of resources and increasing environmental pollution has evoked great interest in the research of materials that are
friendly to our health and environment. Bio polymer composites fabricated from natural fibres is currently
the most promising area in polymer sciences. This is designed to assess the possibility of fibre as reinforcing material in composites. Epoxy resin was made a stiffened panel to conduct tensile test. In this paper it is aimed to explain all possible ways to use natural composites in automobile components. The main advantages of using natural fibers are their degradability and light weight. They are environment friendly and also increase the fuel economy

This document summarizes previous research on using hospital plastic waste as a partial replacement for coarse aggregate in concrete. Several studies found that replacing coarse aggregate with plastic aggregate decreases the compressive strength and density of concrete, but also provides a way to reuse plastic waste. This study aims to further examine the impact resistance of concrete containing hospital plastic aggregate. It reviews literature on using different types of plastic waste in concrete and concludes that while plastic aggregate can be used, more research is needed on properties like durability, ductility, and thermal properties when using hospital plastic specifically.
Experimental Analysis on Strength Properties of Glass Fiber Concrete
"The current world is witnessing the construction of challenging and innovative civil engineering structures. It has been established that when fibers are added in certain percentage to the concrete improves the strength properties as well as crack resistance and ductility. Fibers impart energy absorption, toughness and impact resistance properties to fiber reinforced concrete material and these characteristics in turn improve the strength properties. In the present experimental investigation the alkali resistant glass fiber of diameter 14 micron, length 24mm, having an aspect ratio of 855 was employed in percentage varying from 0, 10 , 20 , 30 , 50 , 60 and 80 to study the effect on compressive, split tensile and flexural strength on M40 grade concrete. At early age strength, the concrete with more than 20 of glass fiber gain strength around 61 until 82 faster than normal concrete. This implies that glass fibers assist in increasing the Compressive strength of concrete. The higher the glass fiber, in the mix the compressive strength also increases. Deepak T. J. | Senyange E.

This document compares the strength of pervious concrete blocks made with natural aggregates and plastic-coated aggregates. Tests were conducted on the aggregates and on concrete cubes made with each type of aggregate. The tests found that properties of the plastic-coated aggregates were similar to the natural aggregates. Compressive strength of cubes made with plastic-coated aggregates was slightly lower than those made with natural aggregates. In conclusion, plastic-coated aggregates can be used to make pervious concrete with only a small reduction in strength compared to natural aggregates.
Use of Plastic Waste in Concrete Mix
This document summarizes a research study that investigated using plastic waste in concrete mixes. Specifically, the researchers mixed high density polyethylene waste with Portland cement at different percentages by volume as a replacement for sand. They found that including up to 13% plastic waste produced concrete with acceptable properties. Compressive strength and density decreased as plastic waste content increased above 13%. However, mixes with 5-13% plastic waste exhibited good workability and mechanical properties after curing, indicating plastic waste can partially replace sand in concrete. The study suggests plastic waste concrete is a promising way to reuse plastic waste and improve sustainability.

The rapid Urbanization and Industrialization all over the world has resulted in the large deposition of Plastic waste
and Waste Tyre Rubber. This waste can be utilized under the proper condition to reduce the Cement content in Concrete.M30
concrete is used for most of the constructional works. The strength of these concrete results has compared with concrete
obtained of Plastic waste and Waste Tyre Rubber varying from 0% to 20 %.Experimental investigations comprised of testing
physical requirements of Coarse Aggregates, Fine Aggregates, Cement and the modifier Waste Plastic and Waste Tyre rubber.
M30 concrete design mix considered as per IS 10262-1982. The said percentage of modifier was blended with the cement
concrete mix and the optimum modifier content was found. Cubes and Cylinders were casted and tested for 28 days strength.
These tests revealed that by adding Waste plastics and rubber as a partial replacement in Fine Aggregate and Coarse
aggregate by volume, the strength of concrete decreased. The cube strength decreased as the percentage replacement increased
due to their poor binding properties. By using Plastic waste and Waste Tyre Rubber as modifier, we can reduce the quantity of
coarse aggregate and fine aggregate by their volume, hence decreasing the overall cost of construction
The modified cement concrete can be used in the construction of small drainage works and rigid pavement.
Effective utilization of waste plastics can be done for a good cause of protecting the global environment and effective solid
waste management.

This document summarizes research on utilizing waste plastic as a partial replacement for fine and coarse aggregates in concrete blocks. Tests were performed on concrete cubes and cylinders with plastic replacements of 0-20%. Results showed that as plastic replacement increased, slump, compressive strength, and split tensile strength decreased. However, concrete with 5-5% and 10-10% plastic replacement achieved strengths suitable for applications like pathways and external walls. Higher plastic replacements produced lighter concrete suitable for non-structural uses. Thus, plastic waste can partially replace aggregates in concrete, reducing costs and environmental impacts while enabling various construction applications.

Concrete using Coconut Fiber –An Alternative
Use of Fiber is one of the vital and emerging trends in Construction Technology. Fiber can be considered as an alternative in the use of an air entraining agent providing sufficient freeze thaw protection and moreover as a reinforcing material. Fiber reinforced materials are composite materials that typically consist of strong fibers embedded in resin matrix. It is a composite obtained by adding a single type or a blend of fibers to the conventional concrete mix. The fibers provide strength and stiffness to the composite and generally carry most of the applied loads. The matrix acts to bond and protect the fibers and to provide for transfer of stress from fiber to fiber through shear stresses. Fibers can be in form of steel fibers, glass fibers, natural fibers, synthetic fibers, etc. The mechanism by which fibres produce resistance to freezing and thawing is that fibres introduction reduces water absorption of the concrete increasing penetration resistance to de-icing salts. Reduced water absorption is a function of the fibres to reduce plastic shrinkage cracking, reducing the ability of water to permeate into the bleed in a concrete. So this research paper describes experimental studies on the use of coconut fibre as enhancement of concrete.

This document summarizes research on using recycled plastics to produce glass fiber composites. Plastics are widely used but not biodegradable, leading to pollution. They can be recycled mechanically by grinding into chips, heating to form yarn, and weaving into fabric. Glass fiber composites are strong but expensive. The study produced composites using epoxy resin with layers of recycled plastic fabric and glass fiber. Testing found the composites had densities from 0.94-1.17 g/cm3, tensile strengths around 50 MPa similar to thermoplastics, hardness increased with more fiber, and impact absorption increased up to 40% fiber content. The composites showed mechanical properties comparable to virgin glass
Effect of plastic waste on tile by using thermosetting method
The plastic tiles are more durable than the traditional tiles with respect to various perspectives as written in results. Looking towards the flexural capacity of the tiles, those can be used under heavy loads. The areas of heavy loads can be garages, workshops, parking, etc. The less wear and tear will be seen in these plastic tiles. Only thing, the cost of the tiles is slightly more than the traditional tiles but this can be overseen with the other properties.
As above project studied that the plastic is harmful for environment and very much amount plastic waste discard in surrounding in daily routing.

The percent study investigates the effective use of waste plastic as a modifier for cement concrete roads. Civilization produces waste products disposals issue of the waste products is a challenge. Solid waste management is the thrust area. The various waste materials, plastic waste and principle solid waste are of great concern these leads to disposal crisis and environmental pollution. On the other side, road traffic is increasing. The load bearing capacity of the roads are to be increased. Our present work is helping to take care of both these aspects. Plastic waste consists of carry bags cups and disposals. Plastic waste which is cleaned is cut into a size such that it passes through 2.3mm sieve using shredding machine. The aggregates mix is heated and the plastic is coated over aggregates and this coated stones can be used for road constructing. By this process a road of 1km length 3.375m width of single lane can consumes 10,00000 carry bags and road strength is increased and found no pot holes. Commonly soil, aggregates, sand, cement can be used in road construction. Natural materials being exhaustible in nature, its quantity is declining gradually. If our material can be utilized in highway construction, the pollution and disposal problems may be partly reduced. The use of the innovative technology will not only strengthen the road construction but also increase the road life as well as will help to improve the environment. In my research work I have done a thorough study on the methodology of using plastic waste coat over aggregates and presented various tests performed on aggregates.

The document examines using waste HDPE plastic as a partial replacement for coarse aggregate in concrete. Tests were conducted on concrete mixtures with 0%, 2%, 4%, 6%, and 8% plastic replacement by weight. Results showed workability decreased with more plastic while compressive and flexural strengths initially decreased marginally but then reduced further with more plastic. Water absorption of the concrete increased along with plastic content. Despite some effects on properties, all results were within acceptable limits, suggesting waste plastic could partially replace aggregates in concrete formulation.

- 1. Carl MontgomeryJr. Faculty Mentor: Dr. Sergio Mendez Chemical Engineering Department California State University, Long Beach Fabrication and Testing of Green Composite Materials for Concrete Reinforcement It is becoming popular to reinforce concrete structures with carbon fiber material that is versatile and extremely strong. However, there are concerns that this carbon fiber material can lead to adverse environmental toxicity as the materials decompose with age. We aim to create a sustainable green alternative for the application of concrete reinforcement. In this research project, we used both the hand lay-up and vacuum resin infusion chemical processes to fabricate composites made from woven hemp or flax fabrics, along with purely synthetic resin as well as a “bio-resin”. Hemp and carbon fiber fabrics were chosen
- 2. because of their lightweight and exceptional mechanical properties. Briefly, for the chemical procedure we employed to prepare the composite panels, first swaths of fabric were measured, cut and set on a hard surface that was the mold. In the hand lay-up process, the resin and hardener were poured over the fabric and a plastic trowel was used to evenly distribute and remove excess resin and unwanted air pockets. After the resin was infused in the fabric, another fresh piece of cut fabric was laid on top of the wet one, and the aforementioned steps were repeated until the desired blade thickness was achieved. The wet panels were then sealed in plastic sheeting and a vacuum was applied at room temperature. The vacuum served to remove unwanted pockets of gas within the plies of fabric, and to compress the panel. After curing overnight under vacuum, the panels were then ready to be trimmed to the specified dimensions. For the vacuum-infusion process, all the fabric swaths were simultaneously infused with the resin, and then left under vacuum overnight for room-temperature curing. The hardened panels were consequently adhered to concrete beams, and we measured the force-versus-displacement curves. Our preliminary results indicate that the green composite panels do impart additional mechanical strength to concrete beams. The introduction of green composites to the concrete will be beneficial to the environment because for one, you will not have to worry about it being environmentally toxic and it is cost much less than carbon-fiber materials. Although carbon-fiber has the advantage of being stronger than green composites, the disadvantage is potential toxic exposure to humans. In the future, we will further refine the chemical process to fabricate the concrete reinforced structures with green composites, and hope to apply green composite to concrete structures.
