Wane irin kauri ake amfani dashi a fenti?

Mai kauri da ake amfani da shi wajen fenti yawanci wani abu ne da ke ƙara danko ko kaurin fenti ba tare da ya shafi sauran kaddarorinsa kamar launi ko lokacin bushewa ba. Ɗaya daga cikin nau'ikan kauri da aka saba amfani da shi a cikin fenti shine mai gyara rheology. Wadannan gyare-gyare suna aiki ta hanyar canza yanayin tafiyar fenti, suna sa shi ya fi girma da kwanciyar hankali.

Akwai nau'ikan gyare-gyare na rheology da yawa da ake amfani da su a cikin ƙirar fenti, kowanne yana da nasa kaddarorin da fa'idodi. Wasu daga cikin abubuwan gyara rheology da aka fi amfani da su sun haɗa da:
