Based on the simplex centroid design, three ternary curing agents (GGBS-EMR-CS (GEC), GGBS-DG-CS (GDC), and GGBS-PG-CS (GPC)) were prepared.

Compared to ordinary Portland cement (OPC), the unconfined compressive strength (UCS) of ESW stabilized with these curing agents increased by 78 %, 178 %, and 98 %, respectively. Sulfate components synergistically activates GGBS and CS, promoting needle-like ettringite (AFt) formation, which fills pores and enhances strength.

While regional Ag-GHG emissions plateaued, the national trajectories fell into three categories: past peaks, plateaus, and growing; and countries in the plateau category account for over 90 % of the regional emissions. Since 1961, the key drivers of Ag-GHG emissions have included population growth (+210 %), rising agricultural labor productivity (+175 %), and a moderate increase in emission intensity (+17 %). However, these trends have been offset by gains in agricultural land productivity (-67 %) and the effects of urbanization (-40 %). Panel data models indicate that the BRI has had a statistically significant negative impact on Ag-GHG emissions in SEA, reducing emissions by 6–8 %. This decline was partially mediated by an increase in agricultural exports. The study provides valuable insights of BRI impact and underlying drivers on Ag-GHG emissions in SEA.
