Concrete anti-cracking expanding agent
The invention relates to the technical field of concrete admixtures, in particular to a concrete anti-cracking expanding agent. The concrete anti-cracking expanding agent is prepared from, by weight, 30-40 parts of calcium sulphoaluminate, 8-16 parts of sepiolite, 4-11 parts of polytetrafluoroethylene, 2-6 parts of nanometer SiO2 and 0.5-2.5 parts of silicone rubber. The concrete anti-cracking expanding agent is remarkable in anti-cracking effect, high in expansion rate, stable in performance and good in shrinkage compensating effect, and the strength of the concrete anti-cracking expanding agent can be matched with the strength of concrete.
