Abstract

<span>Research on concrete containing plastic waste as an alternative polymer material has been <span>conducted.It studied the concrete characteristic through compressive strength, impact testing, <span>thermal conductivity, and density testing. Plastic waste used for concrete manufacture was <span>black because it is strong but light. The goal of this research is to determine the characteristics <span>value of concrete with and without plastic waste mixing. Concrete was mixed with the ratio of <span>1cement: 2 sands: 3 gravel and cement water factor of 0.5. The addition of plastic waste were <span>0%, 2%, 4%, 6%, 8%, 10% of cement mass.Specimens used was (15x15x15) cm cube with <span>sides for compressive strength testing, (8x2x2) cm a block with the size of for impact testing, a<br /><span>cylinder with a diameter of 4cm and thickness respectively 0.2 cm and 0.4 cm for thermal <span>conductivity testing, and a sides (15 x 15 x 15)cm cube with for density testing. The diameter <span>of plastic waste was 0.1 to 0.8 cm. The test was performed at 28 days of concrete age. The <span>result showed that the addition of 4% of plastic waste recorded the best compressive strength, <span>impact testing, and thermal conductivity. In this research, the density was of the range (16 ± 6)<br /><span>x 10<span>2 <span>kg / m³up to(22 ± 4) x 10<span>2 <span>kg / m³, compressive strength(21.8 ± 0.2) x 10<span>6 <span>N / m² of the <span>range (16 ± 0.1) x 10<span>6 <span>N / m²to(21.8 ± 0.2) x 10<span>6 <span>N / m², impact (8.7 ± 0.3)x 10<span>-1<span>Joule to the <span>range (3.5 ± 0.3)x 10<span>-1<span>Joules up to (8.7 ± 0.3)x 10<span>-1<span>Joule and thermal conductivity (6.0 ± 0.5) x <span>10 <span>-5 <span>kcal / ms °C was (1.17 ± 0.5) x 10<span>-5 <span>kcal / ms °C to (6.0 ± 0.5) x 10 <span>-5 <span>kcal / ms °C.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br /></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span>
