建筑材料制品碳排放测算模型研究

Research on Carbon Emissions of Building Materials Products

通过对于国内外建筑材料碳排放测算的相关研究进行总结分析后,本文提出了基于全生命周期理论的建筑材料制品碳排放测算模型,即将建筑材料制品的全生命周期界定为从其原材料获取到最终报废或回收的整个时间段,着重分析了建筑材料制品各个阶段碳排放来源,明确各阶段碳排放的计算方法,同时以蒸压粉煤灰标砖的碳排放测算为例进行测算验证。研究结果表明,本文对于建筑材料制品碳源分析及其计算方法是可行的,同时通过计算分析蒸压粉煤灰标砖生产各个阶段及其生产工艺对其排放量的影响值,有针对性的提出改进相关生产工艺的建议以降低其碳排放量。通过本文的研究,以期能对今后建筑材料制品的碳排放测算具有借鉴意义。

This article proposes an accounting model of carbon emissions of construction materials products by a careful analysis of related researches of carbon emissions accounting of construction materials products in the world Especially, this paper makes a special effort to analyze the source of construction materials products＇ carbon emis- sions in different stages. Also, the calculating methods of carbon emissions in different stages are defined in this pa- per. And autoclaved fly ash brick is taken as an example to verify the calculating methods. Then the outcome re- veals that the analysis of carbon source of construction materials products and the corresponding calculating methods are feasible. Simultaneously, the impact of production technology on carbon emissions of construction materials products can be determined through the calculating. Moreover, special improvements can be put forward to optimize the production technology of raw materials of construction materials products. By doing the research in this paper, it is hoped that the research has its significance to the future study of accounting of carbon emissions of building mate- rials.
