The strength levels of concrete are different, and the amount of cement is also different. Antifreeze should be added according to the amount of cement, and it cannot be more than 5% of the amount. Generally, it is 3% of the amount. %~4%.
Antifreeze concrete is a substance that hardens at negative temperatures, achieves expected performance under specified curing conditions, and prevents moisture in the material from freezing at low temperatures. Ensure the normal construction of concrete under negative temperature and reduce the freezing point in the concrete mixture. It can be combined with water-reducing agent, air-entraining agent, etc. to achieve better antifreeze effect. Used for various concrete projects and during construction in cold seasons.
Makes concrete hydrate normally in a negative temperature environment from 0℃ to -15℃; lowers the freezing point and improves the early strength of concrete.
