Is that good grading of fine aggregate and fineness modulus any related?

Finess Modulus is just a value (number) indicating the fineness or coarseness of the aggregate. So, a river sand (natural sand) will be in the range of2.5 or so to 2.7 and P-gravel (P-stone, Birds-eye) may be around 5.0
Natural sand is used to make concrete block. Natural sand is also used to make ready mixed structural concrete along with water, cement powder, and a coarse 3/8" to 3/4" aggregate like limestone or gravel. SO, there are ASTM standard that regulate the gradation of aggregates for concrete masonry and structural concrete (ASTM C33 is one of them).
Mason sand is used in precast concrete to emulate a fine limestone-like texture. It is also used in mortar and grout.

What is the difference between modulus of compression and bulk modulus and some special for compression?
Modulus of Compression is the ratio of stress to strain in an uniaxial compression action, while as, bulk modulus is the ratio of volumetric stress (hydrostatic pressure) to volumetric strain in hydrostatic loading. These two modulii are inter-related though and are written with the use of Poisson's ratio. 1/m = (3K-E)/6K 1/m = Poisson ratio K = Bulk Modulus E = Elastic Modulus Satisfied? - tell others, not satisfied? - tell me.
What are the difference between result obtained from ultrasonic test and triaxial test?
Triaxial testing will yield static strength properties of the material while ultrasonic measurements will give dynamic strength properties. The two can be related to each other by using various relationships between Young's Modulus, Bulk Modulus, Shear Modulus and Poisson's ratio. Static results should be lower than the dynamic results.
Modulus of rigidity of rubber?
The modulus of elasticity , E, relates tensile stress to tensile strain The modulus of rigidity, G, relates shear stress to shear strain The bulk modulus, K, relates compressive stress to volume strain The three are related using u, poisson ratio of material, that varies generally from 0 to 0.5 E = 9K/ (1 + 3K/G) G = E/2(1+u) G = 3(1-2u)K/2(1+u)
How is concrete made?
Concrete is made from cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. For more information please visit the related link.
What is the elastic modulus of Limestone?
Intact Limestone can have a Young's modulus (E) ranging from:9 GPa - 80 GPa.A,BPoisson's ratio (v) for intact specimens varies from between:0.2 - 0.3.BBulk modulus (K) derived from the above values using the following relation:K = E / (3(1-(2v))Bulk Modulus ranges from:5 GPa - 66.67 GPaShear modulus (G) derived from the above values using the following relation:G = E / 2(1+v)Shear modulus ranges from:3.5 GPa to 33.33 GPaLimestone is a natural earth material and so significant variability in stiffness properties may occur, as such ranges of values are commonly quoted for the strength of rock and other geotechnical materials. Ideally therefore the user would have access to specific lab test data for the rock type in question.Please see the related questions.Sources:A Bell, F. G. (2007).

Modulus of rigidity?
That is the shear modulus, G, related to Young elastic modulus ,E, as G = E/(2(1+u)) where u is Poisson ratio
Is flexural modulus the same as bending stiffness?
It is related. Flexural modulus is the modulus of elasticity (E) in bending and the higher it is the higher the bending stiffness. Technically, bending stiffness is the product of the flexural modulus and the material bending moment of inertia, I, that is EI.
What is an aggregate species?

What is meant by rigidity modulus?
modulus of elasticity, E, relates tension stress, s, to strain,e (s = Ee) modulus of rigidity, G, relates shear stress, t, to angular strain, g (t = Gg) modulus of rigidity G is related to E as G = E/2(1+u) whree u = poisson ratio
What is the tangent modulus of mild steel?
The tangent modulus of steel varies depending on if the steel has yielded.If the steel has not yielded, and is still elastic (stresses less than approx. 275 MPa (39885 Psi) the tangent modulus will be equal to the Young's Modulus, 205 GPa (39885367)If the steel has yielded, the tangent modulus will be related by the Ramsberg-Osgood Equation, but a reasonable value to use would be approx. 1.5 GPa (2175565 Psi)
Why do most economists use the aggregate demand and aggregate supply model?
Because using aggregate demand and aggregate supply is a good way to see the big picture of the economy, which is most of the point of macroeconomics, and because they can be related to each other in meaningful, logical ways.

Yes, although it is not commonly possible. A textbook source is available under "Related Link".
