Relative change in electrical resistance versus applied strain of nanocomposite cured paste specimens. In the plots, R0 is the electrical resistance value with a preload of 0.5 kN. Comparison between results obtained under sine-sweep dynamic compression loads and those obtained under quasi-static compression loads: cured paste with (a) 0.00% MWCNTs; (b) 0.50% MWCNTs; (c) 1.50% MWCNTs.
