单体到区域建筑碳汇计量方法与模型研究
|
摘要
建立一种既考虑混凝土的水灰比、水泥用量与混凝土掺合料,又兼顾建筑环境因素与围护结构的混凝土建筑碳汇计量方法。通过微观酚酞试验、热重试验及电镜能谱试验,分析各混凝土构件固碳量,确定单位体积建筑混凝土固碳能力;以混凝土碳化理论的知识图谱为基础,耦合时间因素与空间因素,建立混凝土建筑单体碳汇计量模型。综合考虑区域尺度规划指标与用地条件限定,建立区域建筑碳汇计量模型,为准确测算城市整体建筑碳汇,建立符合城市碳汇系统提供支撑。
A concrete construction carbon sink measurement method that considers the water-cement ratio of concrete, the amount of cement and concrete admixture, and the consideration of building environmental factors and retaining structure is established. Through the microscopic phenolphthalein experiment,thermogravimetric experiment and electron microscopy energy spectrum experiment, the carbon fixation of each concrete component is analyzed, and the carbon fixation capacity of concrete per unit volume is determined. Based on the knowledge map of concrete carbonation theory, the coupling time factor and space factor are used to establish concrete. Construction unit carbon sink measurement model. Considering the regional scale planning indicators and land use conditions, the regional building carbon sink measurement model is established to provide accurate support for the city's overall building carbon sink and to provide support for the city's carbon sink system.
