Research on concrete containing plastic waste as an alternative polymer material has been
conducted.It studied the concrete characteristic through compressive strength, impact
testing, thermal conductivity, and density testing. Plastic waste used for concrete
manufacture was black because it is strong but light. The goal of this research is to
determine the characteristics value of concrete with and without plastic waste mixing.
Concrete was mixed with the ratio of 1cement: 2 sands: 3 gravel and cement water factor of
0.5. The addition of plastic waste were 0%, 2%, 4%, 6%, 8%, 10% of cement
mass.Specimens used was (15x15x15) cm cube with sides for compressive strength testing,
(8x2x2) cm a block with the size of for impact testing, a cylinder with a diameter of 4cm
and thickness respectively 0.2 cm and 0.4 cm for thermal conductivity testing, and a sides
(15 x 15 x 15)cm cube with for density testing. The diameter of plastic waste was 0.1 to 0.8
cm. The test was performed at 28 days of concrete age. The result showed that the addition
of 4% of plastic waste recorded the best compressive strength, impact testing, and thermal
conductivity. In this research, the density was of the range (16 ± 6) x 102
