Abstract
Ground Calcium Carbonate (GCC) has been used for decades in construction to enhance performance-cost ratio of cement-based products such as grout, mortar or concrete. From dry-mortars to structural concrete, engineers associate GCC with cementitious materials (SCM) to optimize the fluidity, viscosity and reduce the carbon footprint of the mixtures. Nevertheless, the contribution of GCC to the flowability and viscosity of the cement-based systems as well as the range of GCC fineness available to optimize the packing density and strength are poorly appreciated. The benefits of specific GCC products are expected to be particularly useful in formulating concrete or mortar for digital fabrication. This paper will provide an overview of the best practice use of GCC products, aiming to stimulate interest for the material not only for use in digital fabrication with concrete.
