路面水泥混凝土碳汇环境效益的时滞分析与动态核算
Time-Lag Analysis and Dynamic Accounting of Environmental Benefits of Pavement Cement Concrete Carbon Sequestration
摘要
Abstract
Cement materials exhibit significant carbon sequestration potential over their life cycle.However,effective accounting methods for their environmental benefits remain underdeveloped.This study established a time-lag analysis model for pavement cement concrete carbon sequestration based on dynamic characterization metrics,enabling a systematic evaluation of the temporal distribution and environmental benefits of carbon sequestration throughout the life cycle of pavement cement concrete.To address the shortcomings of static accounting approaches,two corrective parameters are proposed:the time factor α and the emission offset β.Results show that over a 100 a timeframe,the total carbon sequestration from cement materials accounts for 22.18%of the CO2 emissions associated with cement production.Compared to the dynamic approach,traditional methods overestimate the environmental benefit of cement carbonation by 53.8%.Moreover,the time-lag analysis reveals that under a 100 a time horizon,α is 0.65 and β is 38 614.79 kgCO2e.These parameters allow for rapid correction of static carbon accounting outcomes.The findings provide a methodological foundation for the accurate quantification of cement carbon sequestration and offer strategic implications for carbon management in long-lived infrastructure systems.关键词
