Abstract :

Polyvinyl-chlorine (PVC) is a material with a wide range of utilities such as construction, packaging, medical materials, and the automotive sector. Because these materials have much time to disappear in nature, it is vital to utilize PVC chip wastes. Concrete was applied on the roads of the Northern campus of Hittites University. PVC chips obtained from door and window manufacturing shops have been added to the concrete mix of concrete bicycle roads. PVC chips were utilized in the concrete by eliminating 0,5 mm aperture size. PVC chips have been added into the transit-mixer from the concrete plant to the construction site. PVC chips were used in the mixture of concrete in the ratio of 1-3 and 5 kg/m3. The largest aggregate size in the mixture is 22.4 mm. The addition of PVC chip to the concrete mix reduced the precipitation value of fresh concrete from 190 mm to 150 mm. The addition of PVC chip has slightly increased the air void ratio of the fresh concrete. Hardened concrete tests, compression resistance, tensile splitting strength, and modulus of elasticity were performed. PVC has been compared with the additive control concrete sample. 5 kg/m3 PVC chip, which was added to the mixture, has reduced pressure resistance by about 11%. It can be stated that the PVC chip contributes positively to the tensile splitting strength and elasticity module values of the concrete. Apart from these tests, firstly, modulus of elasticity tests was carried out on 15*30 cm cylinder samples. Then, compression resistance and tensile splitting strength tests were conducted on the same samples. In the modulus of elasticity test, variations in compression and tensile splittings strengths of examples exposed to repeated compression loads were examined. After the test of elasticity modulus, the compression resistance and tensile-splitting strengths of the samples have decreased. It has been concluded that very thin PVC chip wastes can be utilized in a concrete
