摘要以廢棄混凝土為再生粗集料，再適當摻加一定量的水泥和礦物摻和料，製成再生混凝土。 -
Firstly, the environment harm of the waste rock is studied ; secondly, we research the physics and mechanics property of the waste rock of the dabagou tunnel and get the physics and mechanics property index of waste rock ; thirdly, after comminuting the waste rock and compounding concrete as coarse aggregate, we make the comparison between it and the songshan stone in the fuxin building market at present, it proves to possess extension application value ; fourthly, on the foundation of it, we utilize waste rock as coarse aggregate to compound high strength concrete, steel fiber high strength concrete, polymer cement concrete, asphalt concrete by uniform design and research their mechanics property index by experiment
首先闡述了排矸石對環境產生的危害，其次對大巴溝隧道排矸石的物理力學性質進行了試驗研究，獲得了排矸石的物理力學性能指標。將排矸石粉碎后，作為粗骨料配製成混凝土，與目前阜新建築市場上所用的松山石子進行比較，證明其具有推廣應用價值。在此基礎上，利用均勻設計法，將排矸石作為粗骨料配製成高強混凝土，鋼纖維高強混凝土，聚合物水泥混凝土，瀝青混凝土，通過試驗測定其力學指標，獲得了各種排矸石混凝土的優化方程和最佳配合比。 -
Firstly, the characteristic performance indexes of recycled coarse aggregate, made from crushed waste concrete, were test in detail. causes and influencing factors of the characteristic performance of recycled coarse aggregate were analyzed by them
首先，詳細測試了廢棄混凝土破碎后的再生骨料特徵性能指標，並據此分析再生骨料特徵性能的起因以及影響因素。 -
According to the demands of sustainable development of construction field, the performance of recycled coarse aggregate concrete, produced with crushed waste concrete, one of the most of waste building materials, was studied in systemly in this paper
