Admixture: Types, Functions, Advantages Disadvantages
Functions of Admixture: To accelerate the initial set of concrete, i.e. to accelerate the rate of strength development at an early age. To dim the initial set i.e. to keep the concrete in a working position for a longer time for placement. Also, to enhance workability. To improve the penetration (flowability) and permeability of concrete.
