Analysis of CO2 Emissions from Low Strength Recycled Concrete

Abstract

In this paper, we determined the calculation boundary of CO2 emissions from low strength recycled concrete, and calculated the CO2 emissions from the low strength recycled broken brick concrete RC15 with the target strength of 15 MPa and the ordinary concrete C15, as well as the proportion of CO2 emissions from each material of the low strength recycled concrete. The results showed that the low strength recycled concrete had less CO2 emissions. The results of the proportion of CO2 emissions from each material of the low strength recycled concrete showed that cement was in the largest proportion and other materials were in a smaller proportion.
