High-End Additive For Dry Mortar & Concrete



denka1

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

Recommended Dosage

1m of concrete for precast concrete 30 kg-70 kg for raw material for premix mortar

Coverage

0.2L per m2 @ 200 mm DFT

Description
