Life Cycle Assessment of Precast Geopolymer Products

Reducing the embodied carbon footprint caused by construction projects is being pushed by many countries. One potential solution is the large-scale use of low-carbon building materials like geopolymers (GPs). GPs result from the chemical activation of aluminosilicate materials using an alkaline liqu...
