Abstract
The present invention discloses a micro-nano composite hollow structured nanometer material-modified high-durability concrete material, and according to mass parts, its raw material formula is as follows: cobaltosic oxide, 1000-1500 parts; cement, 1000-1300 parts; dioctyl sebacate, 1000-1500 parts; water, 800-1200 parts; nanocarbon, 1200-1800 parts; nano calcium carbonate, 35-50 parts; sodium silicate, 10-20 parts; micro-nano structured calcium molybdate, 50-80 parts; dipentaerythritol, 60-90 parts; and dioctyl ester 30-60 parts. The present invention enables existing concrete to be improved effectively and stably in terms of shrinkage, cracking resistance and rapid hardening; the synthetic chemical functional material may lower a chloride ion diffusion coefficient of the concrete by more than 50%, cut down shrinkage by more than 30%, and reduce the cracking risk of concrete products by 50%.
