Properties of normal strength Portland cement concrete

Typical properties of normal strength Portland cement concrete are indicated below:

Density : 2240 - 2400 kg/m3 (140 - 150 lb/ft3) Compressive strength : 20 - 40 MPa (3000 - 6000 psi) Flexural strength : 3 - 5 MPa (400 - 700 psi) Tensile strength : 2 - 5 MPa (300 - 700 psi) Modulus of elasticity : 14000 - 41000 MPa (2 - 6 x 106 psi) Permeability : 1 x 10-10 cm/sec Coefficient of thermal expansion : 10-5 oC-1 (5.5 x 10-6 oF-1) Drying shrinkage : 4 - 8 x 10-4 Drying shrinkage of reinforced concrete : 2 - 3 x 10-4 Poisson's ratio : 0.20 - 0.21 Shear strength : 6 - 17 MPa Specific heat capacity : 0.75 kJ/kg K (0.18 Btu/lbm

oF (kcal/kg oC))

uniaxial compression of soft bodies

first i like to thank for the reply i have taken solid cylinder of 80mm dia and 160mm length. material neoprene Neoprene Material Properties shear modulus= 0.0272 MPa poissons ratio= 0.499 density= 960 kg/m3 youngs modulus, E= 0.0815456 MPa Bulk modulus, K= 13.59093333 MPa Incompressibility parameter, d= 0.147156928 iam doing analysis with ansys software(uniaxial compression of soft bodies). iam cnsidering the experimental results to compare with the software result with different material models like Yeoh Model Mooney-Rivlin Model (2 parameter)

Arruda-Boyce Model Neo-Hookean i have to know ASTM standard size for uniaxial compresssion test. neoprene propertis if possible regards nandish rv
