Description
DENKA CSA#20 is made by calcium sulfo Aluminate which mainly consists of lime stone, gypsum and bauxite in an dequate distribution. DENKA CSA#20 reduces dry shrinkage crack as well as improve water tightness in cementitious hydrates.
Features
- Minimize the cracking caused by drying shrinkage (Shrinkage compensation)
- Chemicals Pre-stress
- Increase water tightness
Application
- Dry mix mortar to minimize cracking due to dry shrinkage
- Pre-cast concrete member to improve bending toughness by chemical pre-stress with reinforced bar
