CEM I 42,5 R – Cementos Tudela de Veguín

Type I cement

Format: In bulk.
Use:
- Reinforced and prestressed concretes that require high mechanical strength and stripping and stripping at very early ages.
- Prefabricated atlas mechanical resistance.
- Shotcrete.

UTILIZATION

Reinforced and prestressed concretes that require high mechanical strength and stripping and stripping at very early ages.
Prefabricated atlas mechanical resistance.
Shotcrete.

PRECAUTIONS

Take care of the dosage, the kneading and especially the curing, the latter recommended for at least 7 days, to avoid cracks due to shrinkage and especially during the first hours.
At high temperatures protect the concrete from the action of the sun and the wind to avoid drying out. In case of extreme temperatures (40ºC or more) cool the mixing water and / or the aggregates or suspend the concreting.
Period of effectiveness of the chromium reducing agent: 1 month.
In case of use of specific additives for special concrete applications, previous tests are recommended.
