The possibility of using metaschist as an alternative to claystone which is used as the main
input in cement production has been investigated. In the experimental work, the metaschists
and claystone were used to produce cement separately from the raw materials from their fields,
and their qualities were determined. As a result of the tests carried out, it was understood that
corrective ingredients (iron ore, bauxite etc.) would be needed in order to use the claystone
because of its high SiO2 (silicate modulus 3.97) content. On the other hand, with the metaschist
sample, it has been shown that it can form a raw meal composition singularly without the need for
any corrective ingredients. Although, in the raw meal composition, the silicate module was found
to be low (2.07) the aluminum module was high (2.43), They were found to be within the cement
quality parameters. As a result of detailed mineralogical studies, it has been determined that
the metaschist has a quartz content about 13% lower than claystone. Knowing that the quartz
content is considered to have adverse effects on many production processes such as grindability,
burnability and abrasion, it can be argued that the use of metaschists results in the production of
cement being more economical and of good quality due to its mineralogical structure.
