2021-11-21  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 ...

Fineness Modulus - an overview ScienceDirect Topics

3.4.3 Fineness Modulus. The significance of fineness modulus (FM) is in specifying the proportions of fine and coarse aggregates when designing concrete mixes. The higher the value of FM, the coarser the aggregate. Generally, a lower FM results in more paste, making the concrete easier to finish.

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.

Grading of Fine Aggregate - CivilWeb Spreadsheets

Fine aggregate gradings with higher fineness modulus values are also cost effective as the coarse particles will reduce the water requirement and therefore the cement required for the concrete mix. The fineness modulus is used in concrete mix design to indicate the effects of the fine aggregates on the workability of the mix.
