<p>The present invention relates to: a cement composite comprising a carbon nanotube (CNT)to implement the high dispersion of a carbon nanotube in a cement matrix when preparing a cement composite by mixing a carbon nanotube with low dispersion in cement; a preparation method thereof; and a method for manufacturing a carbon nanotube-cement structure using the cement composite. According to the present invention, the preparation method of the cement composite comprises: (a) a step of mixing a carbon nanotube, silica fume, cement, and fine aggregate and dry mixing the same for a set amount of time; and (b) a step of adding water and a polycarboxylic acid-based superplasticizer to the dry-mixed mixture and mixing the same for a set amount of time.</p> |
