Growth of Grass and Control of temperature of Planting Concrete for Roof Using Recycled Aggregate

재생골재를 이용한 옥상식재용 콘크리트의 잔디생육과 열환경조정효과

The objective of this study is to investigate growth of grass planted with planting concrete using recycled aggregste. Planting concrete blocks are constructed on the roof of existing building. Temperature variation according to planting concrete method are also investigate. According to test results, it shows that grass grows very well under planting concrete method. When planting concrete method is applied, it brings about temperature reducing effects about 1~$2^{\circ}C$ at inner part of the buildings at cooling required period compared to that with existing roof, and at heating required period temperature insulating effects about 2~$4^{\circ}C$.
