VIMATOL-BE | Anti-frost admixture for concrete
Antifreeze, plasticizing additive for concrete floors and screeds
Concrete setting accelerator
Fast curing of concrete in cold weather
VIMATOL-BE | It is a liquid additive for concrete, accelerating the hardening and curing of the concrete mass.
-
When used in fresh concrete, there are processes counteracting the expansion of freezing water;
-
VIMATOL-BE is an auxiliary material and is used for concreting at low temperatures;
-
During concreting, at an ambient temperature of -5 ° C and after sunset, when the temperature drops to -10 ° C, the hardening concrete will already have gained the necessary early strength to withstand the processes that occur later;
- VIMATOL-BE can also be used in any other way to achieve early concrete strength: fast formwork dismantling, walking on the surface of the concrete structure being made, etc.

-
Recommended consumption: 1% by weight of cement;
-
To determine the optimal consumption, it is necessary to create trial batches;
-
Such compositions should be made in proportions from materials that will be used locally. the reaction of chemical additives affects the properties and proportions of other components of concrete;
-
VIMATOL-BE is added to the mixing water or ready-mixed concrete before it is used;
-
The resulting mass is mixed in a concrete mixer for 5 minutes.
Efficiency
- At the recommended dosage, the early compressive strength of concrete increases by 5% per day and more than 30% in two days;
-
On the 28th day, the final set of strength is fixed;
- Recommendations for concreting at low temperatures;
-
Do not concrete if the ambient temperature is less than -15 °C;
-
Do not concrete if the ambient temperature expected in the next 12 hours is less than -10 °C;
-
The temperature of the materials used in the manufacture of concrete must be at least 0 °C;
- The use of high early strength cement 42.5 R or better 52.5 R is recommended;
- The minimum cement content must be at least 350 kg/m3 and the maximum W/C ratio = 0.58, which corresponds to concrete with low water permeability;
-
The use of superplasticizer VIMATOL-SPL simultaneously with VIMATOL-BE allows the production of concrete mass with a low mixing water content;
-
During the curing process, concrete releases heat.
- To prevent heat loss, the structure must be protected for the next 3-4 days, covering it with plastic wrap.
Storage
- The shelf life of VIMATOL-BE is 12 months in sealed original packaging at an ambient temperature of +5 °C to +35 °C.
- Additives to concrete significantly improve its performance, but this does not relieve the user from strict adherence to the laws of Concrete Production Technologies.
