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。

The buildings of Reinforced concrete structures have the highest proportion. Combining its architectural features, on the basis of earlier studies on the building carbon emissions, the paper introduces the theory of carbon balance, the concept model of building life cycle carbon balance and then establishes a calculation models. The paper takes a threefl oor concrete structure building as an example to estimate their carbon balance and analyzes infl uencing factors of carbon balance. The results show that: the amount of carbon absorbed carbon emissions cannot be ignored; using mixed cement(such as fl y ash or blast furnace slag cement) instead of ordinary cement can reduce carbon emissions in the concrete; concrete waste recycling as a coarse aggregate production of concrete can increase carbon sequestration. Thereby this research lays a foundation for future research to reduce carbon emissions from buildings carbon neutral perspective. The results of this study are expected to provide a basis and reference for the construction industry emissions CO2.
