anti shrink cement additive

Anti-shrink

That means, that a reduction of concrete shrinkage can be achieved through adding expanding agents. Expansive additives produce a deformation which is opposed to shrinkage. The speed of this volume increase can be balanced in such a way that its timing is about the same as the volume reduction through shrinkage.

Seven Must-Use Concrete Admixtures (Additives)

Set retarding concrete admixtures are used to delay the chemical reaction that takes place when the concrete starts the setting process. These types of concrete admixtures are commonly used to reduce the effect of high temperatures that could produce a faster initial setting of concrete. Set retarding admixtures are used in concrete pavement construction, allowing more time for finishing concrete pavements, reducing additional costs to place a new concrete batch plant on the job site and helps e
