BWI value of mixture decreases by added colemanite and the experimental BWI values of mixtures were lower than those of calculated, considering their proportions. Hardgrove grindability index (HGI) values of clinker and colemanite are 51.81 and 99.62, and Blaine fineness values are 920 cm 2 /g and 2430 cm 2 /g, respectively. As colemanite addition increases HGI and Blaine fineness values also increase.
