Description
コンクリートのCO2排出量(kg/m3)
=(使用材料のCO2排出量の総和kg/m3)−(コンクリートまたは骨材が吸収したCO2量kg/m3)
291×0.7666+788×0.0037+1065×0.0029
=229.1kg/m3と試算される。
229.1−36.5=192.6kg/m3と試算される。
291×0.4587+707×0.0037+965×0.0029
=138.9kg/m3となる。
707×7.8%+965×8.5%=137.2kg/m3となる。
135kg/m3×27.1%=36.5kg/m3となる。
138.9−36.5−137.2=−34.8kg/m3と試算される。
