Abstract

The effects of binder content and recycling mixed waste plastics(PA) content on the workability, work life and hardening shrinkage of fresh polymer concrete using mixed waste plastics are examined. As a result, the workability of the polymer concretes using mixed waste plastics tend to improve with increasing binder content, PA content and filler content. The work life of the polymer concretes using mixed waste plastics is shortened with an increase in the initiator content and curing temperature. The length change of the polymer concretes using mixed waste plastics tend to increased with Increasing binder content and PA content. The result of the present research is expected to make a contribution to the recycling of final mixed waste plastics and the continuing efforts for the development of use of the recycled products are thought to expand the horizon for the recycling of the final mixed waste plastics.

본 연구에서는 복합 재질 폐플라스틱(PA)을 이용한 폴리머콘크리트의 작업성, 경화시간 및 경화수축에 미치는 결합재 첨가량 및 PA 혼입량의 영향에 대하여 검토하였다. 그 결과 복합 재질 폐플라스틱을 재활용한 폴리머콘크리트의 작업성은 결합재 첨가량, PA 혼입량 및 필러 혼입량의 증가에 따라 증가하는 경향을 나타냈다. 복합 재질 폐플라스틱을 이용한 폴리머콘크리트의 경화시간은 촉매제 첨가량 및 양생온도의 증가에 따라 짧아지는 경향을 나타냈다. 복합 재질 폐플라스틱을 이용한 폴리머콘크리트의 길이변화는 결합재 첨가량 및 PA 혼입량의 증가에 따라 증가하는 경향을 보였다. 본 연구 결과가 복합 재질 폐플라스틱 종말품의 재활용에 조금이나마 기여할 수 있을 것을 기대하며 향후 지속적인 연구개발을 통하여 더욱 광범위한 복합재질 폐플라스틱 종말품의 재활용이 이루어질 수 있을 것으로 판단된다.
