The use of ground limestone and other mineral fillers can enhance the performance, economy, and sustainability of concrete mixtures. Modifications to the conventional proportioning method in ACI 211.1 are needed to incorporate these materials. This document describes ground limestone and other mineral fillers, including their properties, characterization, and qualification, and effects on concrete properties and sustainability. Recommendations are provided for proportioning concrete mixtures with these materials. Keywords: dust-of-fracture; ground limestone; mineral fillers; mixture proportioning; paste volume; powder content; proportioning.
