Cement for passive damping
Multifunctional concretes capable of both structural and non- structural functions are made possible by appropriate admixtures. The use of acid treated silica fume (15% by weight of cement), latex (20 - 30% by weight of cement) or methylcellulose (0.4 - 0.8% by weight of cement) as an admixture gave the vibration damping function (with loss tangent up to 0.18, i.e., up to 390% increase, and loss modulus up to 2.2 GPa, i.e., up to 2200% increase, at 0.2 - 2 Hz loading).
