Sucrose is generally used as a retarding admixture in the construction industry. For LCA (life cycle assessment) analysis of any mix design prepared with the addition of sucrose, what are the values of GWP and embodied energy need to be considered?
Please share any references discussing the same.
Abdelhak Maghchiche
For LCA analysis of concrete mixes with sucrose, consider a Global Warming Potential (GWP) of approximately 0.55 kg CO2e per kg of sucrose and an embodied energy ranging from 0.29 to 1.0 MJ/kg, depending on production methods. These values help assess the environmental impact of using sucrose as a retarding admixture.
