Abstract

The purpose of this study is to analyze the economic effect of the use of recycled aggregate on the construction industry and the effect of increasing the value of the recycled aggregate production industry on the premise of supporting quality assurance technology to promote the high-quality use of recycled aggregate. Accordingly, the production cost of ready-mixed concrete that can be obtained through the use of high-quality recycled aggregate is analyzed according to the recycled aggregate application rate recommended in the recycled aggregate quality standard, The economic effect of general ready-mixed concrete and recycled aggregate-applied rea dy-mixed concrete industry wa s a na lyzed by identifying the domestic rea dy-mixed concrete industry sca le a nd the ra te of satisfaction of recycled aggregate volume, and a cost-benefit analysis method was used to examine the benefits of high-quality recycled aggregate production and sales. As a result, the production cost of ready-mixed concrete is reduced by 2.3~16.2% depending on the application rate, the economic effect of the use of recycled aggregate on the construction industry is about 106.8~142.6 billion KRW, and the effect of increasing the value of the recycled aggregate production industry generated about 1.22 times the benefit.

본 연구는 순환골재의 고품질 사용 활성화를 위해 품질확보 기술의 뒷받침을 전제로 하여 순환골재의 활용에 따른 건설산업의 경제적 효과 및 순환골재 생산 산업의 가치 증대 영향을 분석을 목적으로 한다. 이에 고품질 순환골재 활용을 통해 얻을 수 있는 레미콘 생산비용을 순환골재 품질기준에서 권고한 순환골재 적용 비율에 따라 분석하고, 국내 레미콘 산업규모와 순환골재 물량 충족률을 파악하여 일반레미콘과 순환골재 적용 레미콘 산업의 경제적 효과를 분석하였으며, 비용 편익 분석법을 활용하여 고품질의 순환골재 생산 및 판매에 따른 편익을 검토하였다. 그 결과 레미콘 생산비용은 적용 비율에 따라 2.3~16.2%의 절감효과를, 순환골재 활용에 따른 건설 산업의 경제적 효과는 약 1,068~1,426억 수준을, 순환골재 생산 산업의 가치 증대 영향은 약 1.22배 편익을 발생시켰다.
