Abstract:
According to the IPCC’s Fourth Assessment Report, in order to control the global average temperature increase above pre-industrial to 2.0~2.4℃, we need to realize the 80-50% reduction of the 2000 CO2 emission in 2050. It is estimated that the CO2 emission from concrete construction industry is approximately 10% of the total. In this paper, firstly the general facts on the consumption of resources and energy and the subsequent CO2 emission in concrete sector are described and secondly the recent trend in the development of low environmental impact technologies in cement and concrete industries is discussed. In addition, the direction of environmental standards development by ISO/TC71/SC8 (Environmental management for concrete and concrete structures) will be introduced. Finally, some actions toward the revolution of concrete sector will be proposed.
