New Ecological Concrete that Reduces CO2 Emissions Below Zero Level ∼ New Method for CO2 Capture and Storage ∼.

Abstract: We have developed a new ecological concrete which can achieve a CO₂ emission level below zero by capturing CO₂. This concrete is based on two typical features. One of the features of this concrete is using a special admixture (the γ phase of dicalcium silicate: γ-2CaO.SiO₂) instead of cement. This material has a very low level of CO₂ emissions and hardens the concrete by reacting with CO₂. The other feature of this concrete is capturing the CO₂ contained in the exhaust gas from thermal power stations. In this paper, we set forth the concepts of the development and various results of examination of the ecological concrete. This ecological concrete is named CO₂-SUICOM (CO₂ Storage under Infrastructure by Concrete Materials). [Copyright &y& Elsevier]
