NOVELTY - Concrete waterproof additive comprises 20-30 pts. wt. mica powder, 5-10 pts. wt. silicon carbide whiskers, 4-15 pts. wt. modified steel fiber, 15-30 pts. wt. graphene oxide aerogel, 5-10 pts. wt. calcium gluconate, 20-30 pts. wt. metakaolin, 10-20 pts. wt. sodium dodecylbenzene sulfonate, 30-40 pts. wt. microcrystalline cellulose, 3-5 pts. wt. ammonium salt initiator and 2-6 pts. wt. silane additives. The concrete waterproof additive is prepared by mixing mica powder, microcrystalline cellulose, silicon carbide whiskers, modified steel fibers, graphene oxide aerogel, calcium gluconate, metakaolin, sodium dodecylbenzene sulfonate, ammonium salt initiator and silane additives in the above ratio to obtain concrete waterproof additive. USE - Concrete waterproof additive. ADVANTAGE - The concrete waterproof additive has great application value in the building field, improves the interface effect of the concrete aggregate, flexibility of the concrete, water resistance of the concrete, anti-cracking and anti-corrosion performance, enhances gel activity.
