2022 4 12 Importance of Cement Fineness. The fineness of cement affects hydration rate and in turn the strength. Increasing fineness causes an increased rate of hydration high strength and high heat generation. Bleeding can be reduced by increasing fineness. However increased fineness can also lead to the requirement of more water for workability
