This test method covers determination of (1) chord modulus of elasticity (Young's) and ( ) Poisson's ratio of molded concrete cylinders and diamond-drilled concrete cores when under longitudinal compressive stress. Chord modulus of elasticity and Poisson's ratio are defined in Terminology E6.
Let see the testing video In this video, we show you how you can perform ASTM C469 testing on concrete with ADMET equipment:

Cube size
for compressive strength:
> ASTM C 109 – 50 Square cube – for cement like
materials
> BS 4551 / IS 4031 – 70.1 Square cube – for SLC, non-shrink
structural grouts, PU / epoxy coatings & SLC flooring materials.
> ASTM C39 - 76-mm (3-inch) diameter cylinder - for
SLC, non-shrink structural grouts, PU / epoxy coatings & SLC flooring materials.
> BS 1881: 108 – 150mm and 100mm Square cube for
concrete.
> ASTM C470-81 and ASTM C496:71 - 150 x 300mm cylinder
for concrete.
The relation ship between the Young's Modulus and shear modulus is:
E = 2G (1+ µ)
E = Young's modulus
G = Shear Modulus
µ = Poisson's ratio
