| 摘 要： | 基于LCA生命周期评价理论,计算目标强度分别为5、10、15 MPa的低强再生碎砖混凝土及普通混凝土C15的负荷量,并且对两者进行比较,进行再生碎砖混凝土环境评价.结果表明生产再生混凝土的电耗量、煤耗量及耗油量都比普通混凝土少,并且环境负荷排放量比普通混凝土少,所以回收利用建筑垃圾对从环境保护来说意义重大.

| Abstract: | On the basis of LCA( theory of life cycle assessment),the consumption and emissions of recycled broken brick concrete which strengths are 5 MPa,10 MPa and 15 MPa and ordinary concrete have been calculated. It gets a conclusion on environmental assessment of recycled broken brick concrete. The result shows that the power,coal,fuel consumption and emissions of recycled concrete are less than ordinary concrete. So the recycled concrete is extremely worth to be widely used from the view of environmental protection. |
