In order to improve the comprehensive performance of bulk concrete in locks, the effect of external mixing modified zeolite powder anti-cracking agent on the mechanical, thermal, early cracking resistance and durability of concrete was studied. The results show that the externally mixed 5% zeolite powder anti-cracking agent accelerates the early hydration rate of concrete, improves the early cracking resistance and mechanical properties within 7d more significantly, reduces the risk of early cracking of concrete, and at the same time improves the internal structure of concrete, and improves the anti-freezing and anti-carbonation properties of concrete to a certain extent.
