The circular economy in the construction sector presents significant opportunities to support sustainable infrastructure development, as outlined in the 2030 Sustainable Development Goals and in achieving Taiwan’s 2050 Net-Zero Emissions ambition. In this study, local ternary cementless materials consisting of ground granulated blast-furnace slag, reactive ultrafine fly ash, and co-fired fly ash are proposed to support these opportunities, with polypropylene fiber used as an additive. Tests were conducted on fresh mixture properties, compressive strength, absorption, thermal conductivity, and life cycle assessment. The results showed that workability of the fresh mixture decreased with increasing fiber content. The highest compressive strength was observed in D3 specimen, with a value of 18.44 MPa at 91 days. Absorption tests exhibited an inconsistent relationship with fiber content. The lowest thermal conductivity was recorded in D3 specimens of 0.126 W/m⋅K. Finally, the impact assessment results from the life cycle assessment indicated that the proposed ternary materials had the potential to reduce greenhouse gases emissions compared to conventional cement.

摘要

The circular economy in the construction sector presents significant opportunities to support sustainable infrastructure development, as outlined in the 2030 Sustainable Development Goals and in achieving Taiwan’s 2050 Net-Zero Emissions ambition. In this study, local ternary cementless materials consisting of ground granulated blast-furnace slag, reactive ultrafine fly ash, and co-fired fly ash are proposed to support these opportunities, with polypropylene fiber used as an additive. Tests were conducted on fresh mixture properties, compressive strength, absorption, thermal conductivity, and life cycle assessment. The results showed that workability of the fresh mixture decreased with increasing fiber content. The highest compressive strength was observed in D3 specimen, with a value of 18.44 MPa at 91 days. Absorption tests exhibited an inconsistent relationship with fiber content. The lowest thermal conductivity was recorded in D3 specimens of 0.126 W/m⋅K. Finally, the impact assessment results from the life cycle assessment indicated that the proposed ternary materials had the potential to reduce greenhouse gases emissions compared to conventional cement.
