Properties
- moderate early and twenty eight day compressive strengths,
- very good workability,
- long treatment and perfect bonding of water in concretes and mortars,
- reduced plastic shrinkage crack risk,
- low water content heat (emitted during setting of cement),
- increased resistance to the chemical aggression of the environment.
Working conditions
With ALPOL AC 904 cement, carry out work at ambient temperature from +5°C to +30°C. For concrete and mortar, use potable water and PN-EN 12620- or PN-86/B-06712-compliant sands and gravels, preferably washed, with no organic contaminants (grass, roots) or clay. Use appropriate plasticizers for highly liquid concrete and mortar. Cure freshly made elements to reach desired properties (protect them against adverse environmental conditions such as sun, wind, frost) for at least 7 days.
Storage
Store in original, unopened packages in dry place – shelf life 120 days from production date (between 1st November and 31st March) or 60 days from production date (between 1st April and 31st October). Protect from moisture during transport and storage.
Notes
The specifications are given for the temperature of (20±2)°C and relative air humidity of (65±5)%. The workability may alter in different conditions. Irritating to eyes and respiratory system. Appropriate eye, respiratory system and skin protection measures should be used. Becomes alkaline after mixing with water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Keep away from children. Use water to remove fresh dirt or ALPOL AI 770 cleaner to remove hardened dirt. The manufacturer accepts no responsibility for damage caused by unskilful or inappropriate use of the product.
General recommendations
Work according to building practice, observing health & safety standards and regulations.
