RETARDADOR-FH is a product formulated based on modified phosphates. It's liquid, brown coloured and chloride free, thus not activating corrosion processes in reinforcements. It does not crystallise with low temperatures (freezing point 2 ºC) and allows, depending on the dose and on the composition of mortar and concrete, retarding the normal setting process, adjusting it to the needs in each situation.

The use of RETARDADOR-FH in the mixing water of mortars and concrete provides the following advantages:

- Retarding of the setting, depending on the dose.

- Increase of the final resistance.

- Increase of adherence.

- Speedup in the curing process, from the moment the setting starts.

- Higher plasticity of fresh concrete for the same water/cement rate.

- Dos not cause supplementary air occlusion.
