STRENGTH-ENHANCING AND SET-ACCELERATING

STRENGTH-ENHANCING mainly focus on improving the speed of early strength development and do not change the normal setting time of concrete. Accelerators mainly accelerate the setting and hardening process of concrete, shorten the setting time by promoting cement hydration reaction, and make concrete reach the design strength faster. Sometimes, certain additives can improve early strength and promote cement hydration reaction, and these products are often used in concrete construction in cold weather.
