Material & Application Notes
Non-corrosive accelerating admixture K-Set is a non-corrosive accelerating admixture that does not contain calcium chloride. This admixture speeds up the hydration of cement, leading to quicker setting times and significant early strength gains. K-Set enhances workability, helps prevent segregation, and is beneficial in the early stiffening of mortar and stucco mixes.
Why Contractors Choose It
Contractors choose K-Set to improve release, reduce cleanup, protect formwork, and keep concrete placement moving.

Application
IncorporateK-Setinto the water used for mixing mortars. It can also be added directly to the sand or the full mix but shouldneverbe mixed with dry cement or pre-mixed with other additives. The following dosages are recommended based on the type of cement and environmental conditions:
- Portland Cement:18 to 46 oz per 94 lb bag.
- Masonry Cement:10 to 25 oz per bag. The specific dosage should be fine-tuned based on the materials and conditions of each project.
