Paper Abstract

In this paper, precast concrete (PC) frame and reinforced concrete (RC) frame in a three-storey buildings were analysed to evaluate carbon dioxide (CO2) emissions. The structural members of the two buildings were designed under similar conditions. The CO2 emissions analysis was conducted based on the materials resources that were used in the two building models. The PC frame was cast using a geopolymer concrete as the main material, while normal concrete was used to cast the RC frame. The total CO2 emissions for the RC and PC buildings were 221.57 kg-CO2/m2 and 193.00 kg-CO2/m2, respectively. Hence, the total reduction of CO2 emissions attained in this study was 28.57 kg-CO2/m2. Additionally, the CO2 emissions due to the formworks were 66.67% less in the PC frame compared to the RC frame. Finally, the PC building decreased the total CO2 emissions by 12.90% compared with the RC building, due to the materials used. Therefore, a PC frame system can use as a sustainable alternative to an RC frame system.
