5.1.7. CAC + Life Cycle Assessment

The search with the keywords, calcium aluminate cement and Life cycle assessment (CAC + Life cycle assessment) in the Scopus database returned four results.

Henry-Lanier, et al. [77] evaluated the environmental footprint for the CAC, calculated according to the guidelines defined in the ISO 14,040 and 14,044 standards for Life Cycle Analysis (LCA). After focusing on the methodology and data used, summarizes the intrinsic carbon footprint and energy consumption of CAC production from the cradle to the factory gate. Other data drawn from the LCA literature and databases are provided in this document to give a comparative view of the data for CAC. This document presents results to compare different refractory systems (monolithic and shaped) used for a selected application, showing the intrinsic opportunity to reduce the carbon footprint of specific refractory applications by using monolithic refractories containing calcium aluminate. The conclusions suggest that the use of LCA can be a powerful tool to optimize the types of refractory products and reduce the overall environmental impact of refractories throughout the life cycle of use.
