Accelerating setting

Printer-friendly version

Hydraset-Free non-chloride concrete set accelerator is a ready-to-use liquid admixture that accelerates the initial setting time one to three times faster than normal for mortar and concrete.

Hydraset-Free (Circle 911) improves workability and strength while hastening the hydration of cement. It makes the mix easier to place and speeds construction by shortening the initial set and curing time. Labor and time are saved because forms and other protection can be removed earlier and finishing can be initiated. Hydraset-Free should not be limited to use during months when temperatures are in the 20° to 45°F range. Increased workability and earlier strength also are obtained when temperatures are in the 50° to 65°F range, because anytime the temperature drops below 70°F there is a reduction in the rate of cement hydration.

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, it can be used anytime an accelerated set time is desired to decrease turnaround time. Hydraset-Free is available in 5-gal pails and 55-gal drums.
