Architectural and engineering benefits ... GGBS cement also produces a smoother, more defect free surface, due to the fineness of the GGBS particles. Dirt does not adhere to GGBS concrete as easily as concrete made with Portland cement, reducing maintenance costs.
Abstract: Mechanical characteristics of anchorage-body interface were studied by using fractal theory. The influence to fractal dimension of anchorage-body interface caused by the sand factor of grouting material and the sand fineness was studied.
Both setting times decreased with fineness and LSF of clinker used, but the influence of clinker type was more pronounced in combination with low fineness of cement. It seems that the lower the fineness of cement, the stronger the effect of clinker composition on setting time.

Depends on grain fineness of sand. 60-250 microinches typical. Depends on bead size and ceramic coating grain fineness. Feature Accuracy: Core ...
The fineness of cement influences the drying shrinkage of concrete. When the water content is increased because of fineness, the drying shrinkage is increased. However, if excessive bleeding due to coarseness of the cement takes place, a reduction in the drying shrinkage occurs.
Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.
The fineness modulus is a logarithmic function of the geometric mean of the particle size. The dispersion index is a logarithmic function of the geometric dispersion. An analysis of variance of the fineness modulus and the dispersion index has been made to establish a sampling experiment.

Sand's fineness refers to the average size of sand particles of different sizes mixed together, expressed by fineness modulus (the greater the fineness modulus, the thicker the sand). The thickness of sand reflects the specific surface area of sand.
Effect of Fineness of Sand on Flexural Strength of Concrete Flexural strength is calculated from 28 days testing of beam of size 150x150x700 mm by using following formula.0 to 3.1 increase in FM of sand from 2. strength increases by 11.1 increase in FM of sand …

Aggregates of expanded shale,
3.7 The fineness and particle size distribution of Portland cement The final step in the production of cement is to grind the clinker pellets (and added gypsum) into a fine powder. The resulting individual cement particles have a variety of angular shapes, and a wide range of sizes (see Figure 3-7 below).
