HYDRASET-FREE non-chloride concrete set accelerator is a ready-to-use, liquid admixture. It accelerates initial setting time one to three times faster than normal for mortar and concrete.
HYDRASET-FREE 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, HYDRASET-FREE can be used any time you want to accelerate the set time to decrease turnaround time. HYDRASET-FREE will also provide limited protection to reinforcing steel in concrete structures.
