Ultrasonic measurement of early-age viscoelastic properties of cementitious materials
Cementitious materials are transformed from a fluid to a solid state due to a chemical reaction known as hydration. These cementitious materials exhibit a continuous change in the mechanical properties with time; there is a continuous change in the loss and storage moduli with time through setting and early strength gain. An ultrasonic test setup and data analysis procedures, which provide for continuous monitoring of the hydrating cementitious materials from a very early age, are presented in this paper. The test procedures for obtaining the ultrasonic test data and the inversion subroutines for assessing the material properties of the cementitious material at different stages of hydration are discussed. Experimental test results obtained from a mortar mixture of known composition are presented. The progressive development of the frequency dependent material properties of the mortar, particularly the shear moduli, G' and G'', are shown as a function of time from a very early age.
