The basic reason behind selecting this topic is to reduce CO2 emission and reduce plastic pollution. The purpose of this study is to overcome the plastic material which are being wasted are used as a fine aggregate in Geo-polymer concrete mixture. In geo-polymer concrete there is no use of cement which will reduce the use of cement. As plastic takes very long time to degrade, which can have adverse effects on environment such as polluting soil and sea, death of animals. Plastic granules were used as the replacement for fine aggregate. The compressive and the tensile strength of different specimens were conducted to check the property of plastic granules and how effective is the specimen compared to normal concrete. Six mixes were made to compare with the increments of 0%, 5%, 10%, 15%, 20%. All the stages of replacement showed a notable decrease in compressive strength. After being known that compressive strength was less, tensile strength showed significant strength. The alkaline liquids used in this study for the geo-polymerization process are sodium hydroxide (NaOH), and sodium silicate (Na2SiO3). The test specimens were cubes, cylinders and beams. The geo-polymer concrete specimens are tested for their compressive and tensile strength at the age of 7, 14 and 28 days. The test result indicates that the combination of fly ash and alkaline solution can be used for development of geo- polymer concrete. This study insures that reusing waste plastic as a sand substitution aggregate in concrete gives a good approach to reduce the cost of material and solve some of the solid waste problems posed by plastics. Also to know the compressive strength of geo-polymer concrete with plastic waste and to compare the same with geo-polymer concrete without any replacement of fine aggregate.
