Q-Set is a non-corrosive accelerating admixture which contains no calcium chloride. Q-Set quickens the hydration of cement resulting in shorter setting times and high early strength. Q-Set provides improved workability, helps decrease segregation and is a substantial aid in early stiffening for mortar and stucco mixes. Q-Set is an aqueous solution of organic and inorganic compounds that produces a rapid heat development of the mortar that protects it from freezing during its early life at low temperatures.
