Hydro-Set is a non-chloride concentrated liquid solution to be added to concrete or mortar. It contains no calcium chloride or added chloride ions.
Hydro-Set improves mixing, pouring, placing, speed in setting and final strength of all types of concrete and mortar. When added to concrete and mortar it reduces original water requirements by 5% to 7% while still improving workability.
Hydro-Set is recommended for use during cool and cold weather to accelerate the set time and reduce the risk of frozen mortar and concrete mixes. However, it can be used any time you want to accelerate the set time to decrease turnaround time. Hydro-Set will also provide limited protection to reinforcing steel in concrete structures.
