Benefits
Ideal for making “ fast set concrete”
Allows for quick-demolding
Rapid return to service
Compatible with various aggregates
Reduces efflorescence
Calcium Sulfoaluminate Cement increases strength, reduces set times, and decreases shrinkage of concrete mix designs, used as a stand-alone binder or blended with white portland cement delivers high early strength to incredibly durable concrete and mortar. Conventional retarding admixtures can be used to increase working time sacrificing early strength development
Calcium Sulfoaluminate Cement is ideal for applications requiring high early strength and rapid setting. Concrete and mortar formulated with CSA cement are capable of obtaining the 28-day strength of ordinary cement in just one day.
Suitable projects include
Concrete runway repair
Bridge deck repair
Tunneling
Roadway repairs
Non-shrink grout
Concrete floor overlayment
Zero to Low Shrinkage
CSA cement achieves higher early strength than portlandcement allowing for the formulation of non-shrink and low-shrinkage concrete and mortar products. CSA cement utilizes nearly 100% of the mix water during hydration process, leaving very little water to contribute towards shrinkage. Hydration temperature is considerable lower than comparable quick setting systems .Additionally, because of high early strength development, little or no shrinkage occurs after initial set.
