Abstract: In this experimental work, the HDPE(high density polyethylene) plastic as coarse aggregate is used in fly ash based geopolymer concrete. The geopolymer concrete was prepared with low calcium fly ash and the coarse aggregates of size 10-20mm was replaced with plastic aggregates at different percentages I.e. 0%, 10%, 20% and 30% to study the strength properties such as compressive strength and split tensile strength. Geopolymer concrete was prepared with the use of alkaline solutions NaOH and Na2SiO3. Geopolymer concrete samples at all percentages were cured in oven at 60o c for 24 hours and then kept under room temperature for curing for 3, 7 and 28 days. It has been experimented that, due to the increase of the plastic aggregate percentage in concrete decreases the compressive strength. Geopolymer concrete is a raw material based concrete that leads to the usage of materials which are produced as a raw material from industries and when these raw materials were induced in the geopolymer preparation it leads to the reduction of carbon emissions and acts as a greater concrete towards environment. The usage of plastic in geopolymer concrete is another benefit for the environment. It has been observed that the concrete shows the better strength at 0% replacement of plastic in geopolymer concrete.
