• Reduces shrinkage
• Provides superiour levels of expansion and maintains it for multiple days

Since 1964 Denka has produced expansive additives for cement. These reduce shrinkage, heat of hydration and increase strengths.

In Japan this technology is used to chemically pre-stress concrete. In Europe these additives are used mainly in shrinkage compensated mortars.

Different from gas forming blowing agents (such as aluminium powder) Denka Power CSA forms a stable crystalline structure which gives a durable shrinkage reduction.
