Block C

Freeze/thaw resistance and durability enhancing admixture (Formerly known as Blockadd C)
  • Improves the durability of concrete products against frost and severe weathering conditions.
  • Significantly improves the cohesion of concrete mixes.
  • Improves workability.
  • Chloride-free.
Hyperplast Block C is a mortar admixture that improves the workability, strength, cohesion and improves resistance to freeze/thaw cycles, by entraining a controlled quantity of air to the mortar mix.


Hyperplast Block C is available in 275 gal (1,041 litre) and 330 gal (1,249 litre) IBC totes. Bulk supply in tanker trucks is also available upon request.

Shelf Life

Hyperplast Block C has a shelf life of 12 months from date of manufacture if stored at temperatures between 35 ˚F and 122˚F (2°C and 50°C).


Hyperplast Block C is used to improve workability, strength, surface finish and freeze/thaw cycle resistance properties. It is specially designed for zero slump concrete applications such as concrete pavers, segmental retaining wall units, concrete blocks, pipes, roofing tiles and concrete bricks which are exposed to environments of repeated freezing and thawing.


Hyperplast Block C is suitable to use with all types of cement and cement replacement materials. Hyperplast Block C is compatible with most of DCP's admixtures used in the same concrete mix as long as they are added separately to the concrete mix.
