The invention discloses an anti-crack additive of concrete. The anti-crack additive is characterized by comprising the following components in parts by weight: 2-8 parts of ethylene glycol, 1-7 parts of triethanolamine, 2-10 parts of sodium lactate, 3-9 parts of lignosulfonate, 1-4 parts of tributyl ester, 1-10 parts of anti-crack fibers, 3-10 parts of high-efficiency water reducing agent and 5-15 parts of polyamide epichlorohydrin resin. The anti-crack additive of concrete has the beneficial effects that all the components are ensured to achieve better synergistic effects by determining the ranges of the contents of all the components; especially by selecting the lignosulfonate, the anti-crack fibers and the high-efficiency water reducing agent, the reinforcing agent simultaneously has the advantages that the reinforcing agent has anti-seepage, anti-impact, wear resistant, water reducing, antifreeze and anti-crack effects at the same time and has various functions; when being added to concrete, the reinforcing agent can achieve the effect of obviously improving many properties of concrete, such as better anti-crack, anti-impact and waterproof properties, excellent slump, construction property, and the like.
