- BETOFROST M15 admixture is used in the construction of cast-in-place concrete and reinforced concrete structures, in the manufacture of precast concrete and reinforced concrete products at production facilities and construction sites, and for the preparation of construction mortars within a temperature range of 0°C to -15°C.
- BETOFROST M15 does not reduce the mixture's working time (pot life), does not alter the concrete's color, and does not cause surface efflorescence.
- The admixture is chloride-free and suitable for use in reinforced and prestressed structures; it does not cause reinforcement or concrete corrosion.
- BETOFROST M15 is added to the concrete mix during preparation to prevent freezing during transport and placement, and prior to the start of heat treatment or thermos-curing. When preparing concrete mixes during the winter season, the requirements of TKP 45-1.03-314-2018 (Section 7) must be followed.
- It is recommended to use BETOFROST M15 at ambient temperatures ranging from 0°C to -15°C in combination with Group I plasticizers (Betoplast brand).
DOSING THE ADDITIVEThe recommended dosage of the Betofrost M15 admixture is 1.5–3.5% of the cement mass, calculated based on the admixture's dry matter content. The dosage depends on the forecast minimum ambient air temperature, the concrete mix composition, the water-cement ratio, and the curing and hardening conditions of the structures.
When using Betofrost M15, it is recommended to reduce the mixing water content by utilizing a Group I plasticizer.
Design minimum concrete curing temperature, °C | * Admixture dosage, % by mass of cement, calculated based on the dry matter of the admixture |
0 ÷ -5°С | 1,0-2,0% |
-5 ÷ -10°С | 2,0-3,0% |
-10 ÷ -15°С | 3,0-4,0% |
—The admixture dosage is specified for a standard heavy-concrete mix with a cement content of 400 kg/m³ and a water-cement ratio of 0.4.
The additive is most effective when administered with water.
