METHOD FOR STORING CARBON DIOXIDE IN SOIL
To provide a method for storing carbon dioxide in soil that can contribute to reducing carbon dioxide, which is a cause of global warming.SOLUTION: In a construction work to improve soil such as the ground G, a gas CG in which the volume ratio of carbon dioxide C is higher than that of the air at a construction site or a carbonic acid solution CW in which carbon dioxide C is dissolved is mixed with a mixture of at least one of the soil before improvement, a mixture to be mixed with the soil to be improved, or the soil after improvement. By mixing carbon dioxide C into the mixture, carbon dioxide C is stored in the improved soil.SELECTED DRAWING: Figure 1
【課題】地球温暖化の要因となる二酸化炭素の低減に寄与できる二酸化炭素の土中貯留方法を提供する。【解決手段】地盤Ｇなどの土の改良を行う施工において、改良前の土、改良する土に混合する混合材、または、改良後の土の少なくともいずれかの被混合物に、施工現場の空気よりも二酸化炭素Ｃの体積割合を高めた気体ＣＧ、または、二酸化炭素Ｃを溶解させた炭酸溶液ＣＷを混合する。そして、被混合物に二酸化炭素Ｃを混入することにより、二酸化炭素Ｃを改良後の土中に貯留する。【選択図】図１
