Admixtures are essential components in concrete formulations that serve to modify the characteristics of the concrete. They come in various types and are employed to adjust factors like viscosity, permeability, setting time, water needs, and other attributes of the concrete. By facilitating alterations in both the wet and hardened stages of concrete, admixtures prove advantageous in efficiently meeting structural standards and preserving concrete quality throughout the mixing, transportation, placement, and curing processes, particularly under challenging environmental conditions.
