Abstract: PURPOSE: A hydration heat dissipation concrete composition using carbon nanotubes(CNT) is provided to reduce temperature cracks by increasing the tensile strength of concrete. CONSTITUTION: A hydration heat dissipation concrete composition includes a binding material, fine aggregates, coarse aggregates, and mixing water. The mixing water is consisting of 80-97 parts by water of general water and 3-20 parts by weight of CNT dispersed liquid. The CNT dispersed liquid consists of 96-98 parts by weight of a solvent and 2-4 parts by weight of CNT powder. The amount of CNT is 0.12-0.4 parts by weight based on 100 parts by weight of the mixing water. Magnesium oxide is coated on the surface of the CNT. 0.25-0.5 parts by weight of carbon fiber of 6-12mm length is added based on 100 parts by weight of the binding material.
