Setting begins to occur after the concrete is mixed and even before pouring. The cement in the concrete begins to stiffen after mixed with water. The concrete is beginning to change from liquid form to solid form. During the setting process, the concrete does gain strength, which is the beginning of the
hardening process. When the water ingredient is added to the concrete mix, the concrete is still pliable and flexible, sort of a paste. There is two stages of setting: initial and final setting. Initial setting is when the concrete loses it flexibility and begins to harden. Final setting is when the concrete can sustain some load, but still has some moisture within the mixture.

Fineness Modulus is a measurement of the coarseness or fineness of a given aggregate.
Fineness Modulus is used to know the size of aggregate grains (Particles) for various measurements used in Civil Engineering. To characterize the overall coarseness or fineness of an aggregate, a concept of fineness modulus is developed. The Fineness Modulus is defined as Fineness Modulus = Σ(Cumulative Retained Percentage) 100 To calculate the fineness modulus, the sum of the cumulative percentages retained on a definitely specified set of sieves needs to be determined, and the result is then divided by 100. The sieves specified for the determination of fineness modulus are No. 100, No. 50, No. 30, No. 16, No. 8, No. 4, 3/8", 3/4", 1.5", 3", and 6". Mirza Usman http://www.facebook.com/Mirza.Usman.Blogger
yes, if it is before the initial setting time...

time
When cement is mixed with water, it forms slurry which gradually becomes less plastic with the passage of time & finally a hard mass is obtained. In this process, at a certain stage when the cement paste is sufficiently rigid to withstand a definite amount of Pressure, it is said to have set & the time required to reach this stage is termed as "setting time".

Typically, higher numbers for Blaine Fineness relate to smaller particle size. Think of it as spheres, the smaller you make your sphere the more surface area there is compared to volume, in other words a smaller space contains more surface area. Additionally, the surface structure will affect the fineness without affecting particle size. Blaine Fineness is measured in m^2/ g, this means the mass of sample used will affect the fineness. A denser material may have more surface area but also has a higher mass to achieve it.

Silpozz Micro silica can slightly delay the setting time of concrete, but this can be adjusted with admixtures to meet project needs.
i think the fineness is 583
Carats and fineness are both words relating to gems.
To convert fineness into the percentage of gold, you simply multiply the fineness by 100. For example, if the fineness of a gold alloy is 750, this means it is 750 parts gold per 1,000 parts total, which translates to 75% gold content. Therefore, the formula is: Percentage of Gold = (Fineness / 1000) × 100.
Setting might affect conflict, but usually the conflict is separate. Setting is just where and when the story is taking place, so that can be anywhere and at any time. Conflict is based more on characters because it comes from what they desire and are prevented from achieving.
