Carbon fiber doped conductive cement-based material and preparation method and application thereof
The invention provides a carbon fiber doped conductive cement-based material. The conductive cement-based material is prepared from a mixture of the following components in parts by weight: 85 to 90 parts of cement, 125 to 200 parts of sand, 10 to 15 parts of mineral powder, 1 to 3 parts of redispersible latex powder, 40 to 50 parts of water, 0.5 to 0.8 part of a water reducing agent and 0.03 to 0.06 part of a defoaming agent and carbon fibers, wherein the volume of the carbon fibers accounts for 0.6-1% of the volume of the mixture. The preparation method of the conductive cement-based material comprises the following steps: S1, preparing a carbon fiber dispersion liquid; S2, preparing cement-based mortar; and S3, molding of the conductive cement-based material. The conductive cement-basedmaterial has early strength and rapid hardening performance and is suitable for repair engineering; the durability and the toughness are higher, the resistivity is lower, and the shrinkage of the cement-based material is effectively reduced; the method has repairing and conducting functions, and has a wide development prospect when applied to the fields of electrochemical dechlorination and the like.
