Sažetak
The use of blended cements to mitigate carbon emissions has risen dramatically in recent years. Cementitious mixtures incorporating calcined clays are gaining popularity due to their good performance and widespread availability of clays— particularly the combination of limestone and calcined clay (LC3). The availability of clay and limestone, as well as the impending scarcity of other materials like fly ash and slag, make LC3 an appealing option to the cement industry. While the clays have been deposited all over the world, the kaolinite content, which is the key factor in their overall performance, varies from region to region. Clays with at least 40% kaolinite perform as well as ordinary Portland cement, according to the majority of studies. Within project ACT, funded by Swiss and Croatian Science Foundation fifteen different sources of clay were investigated, among which the highest found kaolinite content was 18%. Additional to low content of kaolinite, some of the clays had quartz and impurities in high concentrations, which can act detriment to the clay's cementitious properties in concrete. Therefore, the removal of these impurities, mainly quartz, could enhance the reactivity of clay, which could consequently give better performance in cementitious system. Particle separation techniques could be used to remove the coarser particles. In this paper, the feasibility and efficiency of particle separation of Croatian clay with low kaolin content are discussed.
