KUTRIPlast W1000 / Plasticizer suitable for concreting at low temperatures

For more information see the documents:

Description and scope

KUTRIPlast W1000 is a liquid concrete admixture that allows concreting in winter conditions (at temperatures up to – 20 °C).

Appearance Brown liquid
Density (20 °C), kg/m3 1330 ±30
pH value 6,0 ±1,0
Pour point , °C ispod – 18
Chlorides ≤0,10 %

KUTRIPlast W1000 lowers the freezing point of water and thus prevents freezing of the water used to prepare the concrete at negative outdoor temperatures.
When the temperature reaches positive values (above + 5 °C), the hydration of the cement resumes, and also setting and herdening of the concrete.

Action of the KUTRIPlast W1000 prevents the destruction of the concrete structure at negative temperatures during the period until the strength reaches a critical value.

KUTRIPlast W1000 has a plasticizing effect because it lowers the surface tension of water and provides better wetting of cement and aggregates.

This enables the reduction of water in the concrete mass (by about 10%), which is another factor that reduces the risk of freezing water in the concrete. These properties are also used in the production of waterproof concrete in winter conditions.


KUTRIPlast W1000 is dosed 2 – 3%, by weight of cement, depending on the air temperature, the amount of cement and the weight of concrete. Increased dosage (overdose) does not adversely affect the quality of the concrete and its behavior.

KUTRIPlast W1000 is added to the concrete preparation water or directly into the concrete mixer.


KUTRIPlast W1000 is chloride free and can be used for all types of concrete structures and does not promote corrosion effects on steel embedded in concrete.

KUTRIPlast W1000 is used for concreting to an air temperature of -10 °C, taking into account:

  • use cement with higher hydration heat and lower standard consistency
  • use at least 300 kg of cement per m3 of concrete
  • do not use an engine that is frozen or mixed with snow
  • use KUTRIPlast W1000 plasticizing effect and prepare the concrete with reduced water content
  • protect concrete from the direct effects of frost and wind (first 24 hours) in the case of thin structures

KUTRIPlast W1000 is also used for plastering, but in this case maximum dosage of additives is required and great care is taken to protect freshly plastered surfaces.
Due to the relatively small thickness of the plaster, a smaller amount of the hydration heat of the cement is used, so there is a greater risk of freezing.

Mixing with other additives

KUTRIPlast W1000 can be combined with the KUTRICrete superplasticizer to prepare liquid, pumped concrete, or to take advantage of other properties of the superplasticizer.
Combination with additives that slow down the speed of setting and hardening of concrete should be avoided like KUTRITard.

Packing and storage

KUTRIPlast W1000 is durable for one year in tightly sealed packaging.

KUTRIPlast W1000 is delivered in 50 kg cans, 200 kg barrels and 1000 kg IBC containers.
