【摘要】：钢筋混凝土结构建筑在各种结构类型建筑物总量中所占的比例最高,结合其建筑特点,在早期研究建筑物碳排放的基础上,引入碳平衡理论,建立建筑生命周期碳平衡概念模型及计算模型。以一栋三层钢筋混凝土结构建筑为例估算其碳平衡,并在此基础上分析碳平衡的影响因素。结果表明:碳吸收量相较于碳排放量不能被忽略;在混凝土中使用混合水泥(如粉煤灰或高炉矿渣水泥)替代普通水泥可以减少碳排放;混凝土废弃物回收再利用作为粗骨料生产混凝土可以增加碳吸收。此研究结果可望为建筑业从碳平衡的角度减排CO2提供依据和参考。
[Abstract]:Reinforced concrete structure buildings account for the highest proportion in the total amount of various structural types of buildings. According to the characteristics of the buildings, the carbon balance theory is introduced on the basis of the early research on the carbon emissions of buildings. The concept model and calculation model of carbon balance in building life cycle are established. A three-story reinforced concrete structure is taken as an example to estimate the carbon balance. The results show that the carbon absorption can not be ignored compared with the carbon emission, and the use of mixed cement (such as fly ash or blast furnace slag cement) instead of ordinary cement in concrete can reduce carbon emission. The recovery and reuse of concrete waste as coarse aggregate to produce concrete can increase carbon absorption. This study is expected to provide the basis and reference for the construction industry to reduce CO2 from the perspective of carbon balance.
