This study develops three new Low Carbon Concrete (LCC) mix designs with characteristic cylinder compressive strengths of 32 MPa (C32). 25 MPa (C25). and 20 MPa (C20). By using a Taguchi design of experiment (T-DoE) model and combined it with Grey relational analysis (GRA) and Principal component analysis (PCA) for multi-response optimization. https://miamistares.shop/product-category/seat-products/
