Properties of Fresh Concrete
Mehta and Monteiro: Concrete
Importance
If concrete is very dry, it cannot consolidate
well and will end up with lots of voids.

Fineness modulus is the sum of the total
percentages retained on each of the
specified sieve divided by 100. The
specified sieves are 3, 1 1/2, 3/4 and 3/8
in and Nos. 4, 8, 16, 30, 50 and 100.

Determine the lattice points per cell
in the cubic system
Simple cubic:
Lattice points are located only at the corners of the cube
8 corners (1/8) = 1
In BCC unit cells, lattice points are located at the corners and the center of the cube:
8 corner (1/8)
