Abstract
The invention discloses electrostatic self-assembly carbon nano tube/nano-carbon black composite mortar. Raw materials of the mortar comprise cement, silica fume, electrostatic self-assembly carbon nano tubes/nano-carbon black, a water reducing agent, sand and water. The minimum static resistivity of the mortar reaches 0.45 omega*m, the range of an absolute value of the resistivity change rate is 3.3%-22.1%, the change range of stress sensitivity is 0.40%-2.69%/MPa, and the change range of the strain sensitivity is 105-704. Compared with the prior art, the electrostatic self-assembly carbon nano tube/nano-carbon black composite mortar and the preparation method thereof solve the problem about dispersion of nanofiller in the mortar very well, and the carbon nano tubes and the nano-carbon black have the collaborative conductive effect, so that the mortar can acquire very low static resistivity and has excellent pressure-sensitivity by the aid of a small mixing amount of electrostatic self-assembly carbon nano tubes/nano-carbon black.
