Analysis on carbon emission for inorganic composite sintered shale hollow brick based on life cycle assessment

The calculation model and formulas about carbon emission of inorganic composite sintered shale hollow brick based on life cycle assessment were established in this paper,and the carbon emission of composite brick was calculated.The comparison with common sintered brick and hollow brick shows that,carbon emission of WJZB190×200×115 was 145.23 kg/hundred bricks,and that of WJZH190×220×115 was 150.98 kg/hundred bricks.The comparative analysis reflects that carbon emission of composite brick was 32% lower than the sintered common brick and 3.2% higher than hollow brick.
