Abstract

The cement industry is a significant CO 2 emitter mainly due to the calcinations of raw materials and the combustions of fuels. Some measures have been considered to reduce the CO 2 emissions in cement industry, of which alternative raw materials are the most efficient practicing way. In this study, a LCA-based CO 2 accounting framework with alternative raw materials was constructed to analyze the CO 2 emissions from concrete with different kinds of low carbon substitution, within which cement production process was divided into six stages associated with the environmental impacts. A better routine is expected to understand the environmental hazards of cement products and to optimize the design to reduce adverse environmental impacts.
