高速公路建设期水泥混凝土物化阶段碳排放测算研究

Research on Carbon Emission Measurement in the Physicochemical Stage of Cement Concrete during Expressway Construction

当前,全球温室效应加剧,交通行业绿色低碳发展已成为主要方向之一。碳排放数据精准计算与分析是交通行业实现“双碳”目标的迫切需求和必要手段。文章通过定义高速公路水泥混凝土物化阶段,建立了碳排放测算模型,分析了水泥混凝土物化阶段碳排放并对固废材料的减碳作用进行测算。测算结果表明:在界定的混凝土物化阶段,碳排放量均值为256.55 kgCO_(2)/m^(3),其中,水泥生产过程中的碳排放最高,高达93.85%。

At present,the global greenhouse effect is intensifying,and promoting the green and low-carbon development of the transportation industry has become one of the main development direction.The accurate calculation and analysis of carbon emission data is an urgent need and necessary means for the transportation industry to achieve the"dual carbon"goal.The carbon emission measurement model is established by defining the physicochemical stage of expressway cement concrete,the carbon emission in the physicochemical stage of cement concrete is analyzed,and the carbon reduction effect of solid waste materials is measured and calculated.The measurement result shows that:the average carbon emission is 256.55 kgCO_(2)/m^(3)in the defined physicochemical stage of concrete,in which,the carbon emission in the cement production process is the highest,reaching 93.85%.
