Elastic moduli of hardened portland cement and tricalcium silicate pastes -- Effect of porosity

Helmuth, R.A. / Turk, D.H.

Resonance frequency method was developed for use with 1 to 2 mm slabs of hardened pastes; elastic moduli calculated from resonance frequencies were strongly porosity dependent; Poisson's ratio was not; elastic moduli vary as (1-epsilon)³ where epsilon is porosity; this relationship is obtained from consideration of porosity of paste; two portland cements designated by numbers 15366 and 15754, with specific surface areas of 4470 and 3420 sq cm/g Blaine respectively, and pure tricalcium silicate of 4410 sq cm/g specific surface area were used to prepare hardened paste specimens.
