Greenhouse gas emission analysis for each material composition of a cement reactive siloxane polymer-based penetration resist agent

초록

According to maintenance technology, in order to calculate the increase in service life of structures and reduction in environmental load, a quantitative environmental impact assessment is necessary. There must be a basic unit quantifying environmental impact emission for building materials. This study aims to use polysiloxane and perform life cycle greenhouse gas emission evaluation based on an optimal composition ratio of a cement reactive siloxane polymer-based compound and penetration resist agent. Accordingly, the greenhouse gas emission of this agent was evaluated by securing basic data and life cycle inventory database for raw materials such as isophorone diisocyanate, ethylene glycol, and polydimethylsiloxane. An evaluation of greenhouse gas emission of the penetration resist agent was performed, and the greenhouse gas emissions of the agent at different composition ratios were comparatively analyzed. According to the evaluation, the carbon dioxide emission 1.68 kg-CO2eq/m2 showed the highest contribution 93.51% in the overall emission of 1.94 kg-CO2eq/m2 © International Journal of Sustainable Building Technology and Urban Development.
