Analysis on Life Cycle CO2 Emission of Aerated Concrete Production in China

摘要

Aerated concrete is a new type of wall material with beneficial features like light weight,heat insulation,fire prevention and low energy consumption.As a key milestone in wall materials innovation and energy-saving of building system,it has been proven to be an ideal wall material which can replace traditional clay brick through years of application and practice.This study calculated the CO2 emissions in all the stages of life cycle of aerated concrete production.Compared with clay brick,the life cycle CO2 intensity of aerated concrete block will be decreased by 67.4％ with the same insulation effect.Study on the environmental loads of aerated concrete industry will provide theoretical base for the carry out of energy-saving and emission reduction,the formulation of clean production and the development of recycling economy.
