The invention discloses a waterproof additive acting on concrete. The waterproof additive comprises the following components in parts by weight: 280-350 parts of silicon dioxide, 30-50 parts of 60-80-mesh quartz sand, 3-7 parts of polyacrylic fiber, 2-5 parts of copper sulfate, 1-3 parts of alum, 60-90 parts of stearic acid and 5-10 parts of methyl ethyl ketone peroxide. The waterproof additive has the function of increasing the waterproof effect of concrete so that the duration of the waterproof effect can be further prolonged, the problem that the generation of water seepage causes corrosion to reinforcing steel bars can be prevented and the firmness of a whole concrete structure is ensured.
