C-Set 
Calcium chloride accelerating admixture
C-Set is an accelerating admixture for Portland Cement, masonry cement and stucco mortars. C-Set accelerates the hydration of cement resulting in shorter setting times and high early and overall strength. C-Set provides improved workability, helps prevent segregation and is a substantial aid in early stiffening for mortar and stucco mixes.
- Speeds Up Setting Times: Reduces setting time by one to three hours, essential in fast-paced construction environments.
- Cold Weather Protection: By accelerating early strength, C-Set helps protect mortar from freezing during initial set.
- Enhances Workability and Performance: Improves production efficiency by enhancing mortar workability, reducing set time, and lowering permeability.
- Boosts Strength: Provides high early strength and improves overall strength of the mortar.
- Versatile: Compatible with gray, white, or colored mortars.
- Environmentally Friendly: Complies with V.O.C. standards.
Application
To achieve optimal results, mix C-Set with the water used in preparing mortar. It can also be added to the sand or directly into the mortar batch. Avoid mixing C-Set directly with dry cement or other additives before integration into the mortar.
Recommended Dosage
- Portland Cement: Add 18 to 46 oz of C-Set per 94 lb bag, depending on the desired acceleration.
- Masonry Cement: Use 16 to 32 oz per bag. Adjustments should be made based on specific job requirements and materials used.
Packaging
- 55 gallon drums
- 5 gallon pails
- 1 gallon jugs (sold in cases of 4)
Shelf Life
C-Set should be stored in its original, tightly sealed container, maintaining its quality for up to 2 years from the manufacturing date.
Standards
C-Set meets the ASTM C-494 Type C standards as applicable to mortar, ensuring compliance with the industry requirements for a chloride masonry accelerator.
