| titleOfInvention | Waterproof and impervious concrete additive with self-repairing function and preparation method thereof |
| abstract | The invention discloses a waterproof and impervious concrete additive with a self-repairing function, which is formed by compounding calcined tuff, tuff powder, gypsum and a composite modifier through mechanical force, wherein the waterproof and impervious concrete additive comprises the following components in percentage by mass: 10-30% of calcined tuff, 50-80% of tuff powder, 4-15% of gypsum and 1-5% of composite modifier. The waterproof and impervious concrete additive can endow concrete with excellent working performance, good volume stability and self-repairing function, and can show good secondary impermeability; in addition, the recycling of the tuff powder and the like can be realized, and the method has important economic and environmental benefits. |
