For the construction of cast-in-place and precast-monolithic concrete and reinforced concrete structures and buildings. For the manufacture of precast concrete and reinforced concrete products at construction sites and casting yards.
APPLICATION OF THE ADMIXTUREBETOFROST P150 admixture is applied in the construction of cast-in-place concrete and reinforced concrete structures, in the manufacture of precast concrete and reinforced concrete products at casting yards and construction sites, and for the preparation of mortars within the temperature range of 0 °C to -15 °C.
During the preparation of concrete mixes in winter periods, compliance with the requirements of SNiP 3.03.01-87 is mandatory.
The admixture is recommended for use at ambient air temperatures ranging from 0 °C to -15 °C.
ADMIXTURE PROPERTIESBETOFROST P150 admixture does not reduce the pot life of the mix, does not alter the color of the concrete, and does not cause efflorescence on the surface.
USAGE
The use of BETOFROST P150 admixture reduces the amount of mixing water by 10-20 % from the initial value.
When used as a Group I efficiency plasticizer, the minimum dosage of the admixture must be 0.9 % by weight of cement, calculated as dry matter.
The effectiveness of the admixture is maximized when introduced together with the mixing water.
ADMIXTURE DOSAGEThe recommended dosage of BETOFROST P150 admixture is 0.6-1.5 % by weight of cement, calculated as dry matter.
The dosage depends on the forecasted minimum ambient air temperature.
Design minimum concrete curing temperature, °C | Additive dosage, % by mass of cement, calculated on a dry basis*** |
0 ÷ -5°С | 0,6-0,9% |
-5 ÷ -10°С | 0,9-1,2% |
-10 ÷ -15°С | 1,2-1,5% |
*– The dosage is specified for an average heavy-weight concrete composition with a cement content of 400 kg/m3 and a water-cement ratio of 0.4.
The admixture contains no chlorides, is suitable for use in reinforced and prestressed structures, and does not induce reinforcement corrosion.
The dosage depends on the concrete mix design, product type, and structural features of the component (Consult with our specialists).
