Abstract The aim of this project is to replace cement with plastic waste in paver block and to reduce the cost of paver block when compared to that of convention concrete paver blocks. At present nearly 56 lakhs tones of plastic waste is produced in India per year. The degradation rate of plastic waste is also a very slow process. Hence the project is helpful in reducing plastic waste in a useful way. In this project we have used plastic waste in different proportions with quarry dust, coarse aggregate and ceramic waste. The paver blocks were prepared and tested and the results were discussed.

INTRODUCTION
Paver block paving is versatile, aesthetically attractive, functional, and cost effective and requires little or no maintenance if correctly manufactured and laid. Most concrete block paving constructed in India also has performed satisfactorily but two main areas of concern are occasional failure due to excessive surface wear, and variability in the strength of block. Natural resources are depleting worldwide at the same time the generated wastes from the industry and residential area are increasing substantially. The sustainable development for construction involves the use of Non- conventional and innovative materials, and recycling of waste materials in order to compensate the lack of natural resources and to find alternative ways conserving the environment.
Plastic waste used in this work was brought from the surrounding areas. Currently about 56 lakh tonnes of plastic waste dumped in India in a year. The dumped waste pollutes the surrounding environment. As the result it affects both human beings and animals in direct and indirect ways. Hence it necessary to dispose the plastic waste properly as per the regulations provided by our government. The replacement of plastic waste for cement provides potential environmental as well as economic benefits.
With the view to investigate the behaviour of quarry rock dust, recycled plastic, production of plastic paver block from the solid waste a critical review of literature was taken up. An attempt was made by Nivetha C et.al1 to reuse the solid waste quarry dust fly-ash and PET with an aim not to lose the strength far from original Paver blocks. From the observations of test results, PET can be reused with 50% of quarry dust and 25 % of fly-ash in Plastic Paver block. The physical and mechanical properties of materials used in Plastic Paver block were investigated. For the test 6 cubes cube were cast for measuring Compressive strength. Satish Parihar et.al2 used recycled plastic aggregate in various proportions in concrete mix and check there stability. Amount
of waste plastic being accumulated in 21st centuries has created big challenges for their disposal, thus obliging the authorities to invest in felicitating the use of waste plastic coarse aggregate in a concrete is fundamental to the booming construction industry. Three replacement levels of 10 %, 20
%, 30 by weight of aggregates were used for the preparation of the concrete. Poonam Sharma3 et. al. discussed about cement concrete paver blocks for rural roads. The study of Joel Santhosh and Ravikant Talluri4 indicated that fly ash and waste glass powder can effectively be used as cement replacement without substantial change in strength.

Quarry dust
Crushed sand less than 4.75 mm is produced from rock using state of crushing plants. Production of quarry fines is a consequence of extraction and processing in a quarry and collected from the near-by quarry.

Coarse Aggregate
Locally available coarse aggregates were used in this work. Aggregates passing through 12mm sieve and retained on 10mm sieve were sieved and tested as per Indian standard specification IS:383-1970
Ceramic Waste
The principle waste coming from the ceramic industry is the ceramic waste. The disposal of these waste require large area. It is very difficult to find a use of ceramic waste produced.

Mix Ratio
Block type1- Three paver blocks were casted using mix ratio provided below
Plastic waste = 1 Quarry dust = 0.75 Aggregate= 0.75
Block type 2 – Three paver blocks were casted using mix ratio provided below
Plastic waste = 1 Quarry dust= 1.5
Aggregate = 2 Ceramic waste = 0.75
Block type 3 – Three paver blocks were casted using mix ratio provided below
Plastic waste=1 Quarry dust= 1.5
Gravel = 2
Ceramic waste = 0.75
2.4 Testing of Specimens
Compressive strength for paver blocks
Plastic paver blocks of size 215X115X6mm were casted. The maximum load at failure reading was taken and the average compressive strength is calculated using the following equation.
Compressive strength (N/mm2) = (Ultimate load in N / Area of cross section (mm2))

Preparation of Test Specimens
Plastic wastes are heated in a metal bucket at a temp of above 150. As a result of heating the plastic waste melt. The materials quarry dust, aggregate and other materials as described in previous chapter are added to it in right

proportion at molten state of plastic and well mixed. The metal mould is cleaned through at using waste cloth. Now this mixture is transferred to the mould. It will be in hot condition and compact it well to reduce internal pores present in it. Then the blocks are allowed to dry for 24 hours so that they harden. After drying the paver block is removed from the moulds and reay for the use.

Fig 2 Casting and Drying
As the paver block is made of plastic we need to know its melting point hence over test is performed. The paver block is kept in oven for 2houes in oven and after 2 hours its condition is verified.
