Utilization of Waste Polythene as Low Cost and Eco-Friendly Material in PPC Concrete

The rapid growth of urbanization and industrialization in the world leads to lot of infrastructure development. And this creates several problems like shortage of construction materials, increased wastes production, etc. From many decades concrete is a versatile material for construction. Concrete is a mixture of cement, coarse aggregate, fine aggregate and water. Now days, construction industries is in need of finding cost-effective and cheap materials for increasing the strength of concrete structures. Hence an attempt has been made in this analysis or investigations to study the impact of addition of domestic waste or very cheap material like polythene waste. In this paper, there is a reuse of waste polythene as partial replacement of coarse aggregate in M25 concrete conforming to IS:10262-2009 guidelines was designed as the referral concrete with the mix proportion of (1:1.54:3 ) and water-cement ratio(W/C) of 0.45 by weight taking with 0.6% super plasticizer dose by weight of cement. It is observed that, the compressive strength increases up to the optimum percentage of waste polythene (0.80% of weight of cement) and after that it tends to decrease. I also observed that, the flexural strength increases with increase in percentage of waste polythene in concrete. However, the optimum dose of polythene is 0.80% (by weight of cement). | Volume – 2 | Issue – 3 | Mar-Apr 2018 6470 | www.ijtsrd.com | Volume Journal of Trend in Scientific and Development (IJTSRD) International Open Access Journal , , Manish Chaudhary Department of Civil Engineering Higginbottom University of Agriculture, Technology and Sciences Allahabad, Uttar Pradesh Keyword: Concrete, plastics, Compressive strength, Flexural Strength

INTRODUTION
As the world population grows, construction materials, increased wastes production, etc. One solution to this crisis is recycling wastes into useful products. The wastes plastic in household is large and increases with time. In every country the waste composition is different to each other, since it is affected by many characteristics like socioeconomic characteristics, consumption patterns and waste management programs, but in general the level of plastics in waste composition is too high. The largest component of the plastic waste is polyethylene, followed by polypropylene, polyethylene Terepthalate and polystyrene 3 . The large volume of materials required for construction is potentially a major area for the reuse of waste materials. Recycling in concrete has many advantages since it is widely used and has a long service life, which means that the waste is being removed from the waste stream for a long period. 3 Because the amount of mineral aggregates required in concrete is too large, the environmental benefits are not only related to the safe disposal of bulk waste, but also to the reduction of environmental impacts arising from the extraction of aggregates.
By using these plastic wastes in concrete will lead to sustain the concrete design and protect the environment.

The properties of plastic that make it so International Journal of Trend in Scientific Research and Development (IJTSRD) ISSN: 2456-6470 Page: 2054 precious also make its disposal challenging, such as its durability, light weight and low cost. In many cases, plastics are thrown away after one use, especially packaging and sheeting, but they are durable and persist in the environment. Soroushianet al.
(1995) stated that polypropylene can be used as synthetic fibers to increase the toughness of concrete.    Table 2.  fig. 1. It was shredded in very fine random fibre form. The specific gravity for polythene waste is 0.41 and aspect ratio lies between 250 and 500.
However, similar material properties were reported by Ankit et al.

Water -Potable water was used for mixing the concrete mix in entire investigation and for curing the concrete in the determination of the optimal percentage of stone dust as fine aggregate replacement.

EXPERIMENTAL DESIGN
The cubes were cast in steel moulds of inner dimensions of 150 x 150 x 150 mm, all the materials are weighed as per mix proportion of 1:1.54:3 with a W/C ratio of 0.45 which correspond to M25 grade of concrete. Cement is replaced by waste polythene. Each mix comprises of various percentages of cement replacement material in increasing order i.e. 0.20%, 0.40%, 0.60%, 0.80% and 1.00%, respectively in replacement. The specimens were cured for a period of 7, 28 and 56 days.

RESULT AND DISCUSSION
A. Compressive Strength of waste polythene concrete: -The compressive strength of concrete made using polythene waste after 7, 28 and 56 days are given in table 3. It is observed that the compressive strength at 28 days was not meeting the target mean strength of M-25 grade concrete. This may be due to the use of super plasticizer which to some extent acts as retarder. However, the strength at 56 days is satisfactory. The results of compressive strength test are shown graphically in figure-1 for visual observation. It is observed that, the compressive strength increases up to the optimum percentage of waste polythene (0.80% of weight of cement) and after that it tends to decrease. However, the strength of 1% waste polythene concrete is also more than that of referral concrete. Split tensile strength of waste polythene concrete: The split tensile strength of concrete mixes by partial replacement of cement by waste polythene fiber was cast cylinder and tested at 7, 14 and 28 days.. The experimental set up for determination of split tensile strength is shown in table-4. These results are shown graphically also in figure-2, for visual observation. It is observed that, the split tensile strength increases with increase in percentage of waste polythene in concrete. However, the optimum dose of polythene is 0.80% (by weight of cement).
