Addition Rates FDN can be added directly or added in after soluted. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%.

Instructions Prepare solutions as required.

Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%).

 

The agent can be combined with other agents if pilot development or laboratory test is satisfied.
