An environmental assessment of metakaolin as a supplementary cementitious material (SCM) through an integrated production-process-simulation and Life-Cycle-Assessment (LCA) approach is presented in this work. Initially. process simulation models were developed to reproduce the basic stages of the metakaolin production process. The effect of various operational parameters and scenarios. https://thegreensjunglebeautyshops.shop/product-category/cheek-tint/
