Our shrinkage reducer reduces the shrinkage of concrete by about 50%. That makes it a valuable helper with the casting of otherwise problematic concrete objects, such as when it comes to preventing the arching of very thin-walled panels, or if too-rigid internal forms hinder a crack-free shrinkage of the casting.
The active substance containing alcohol ethoxylate provides a slower and more uniform drying of the concrete, acting as a flowing agent during concreting and slightly reducing the strength of the hardened concrete. We recommend shrinkage reducer especially for high-strength concrete mixtures.
Dosage: 5-20 grams per kg of cement, added simultaneously with the mixing water.
