The DURA-MIX® Quality Standard for Concrete

DURA-MIX® is a quality standard designed to ensure the concrete you order in Alberta meets all requirements of the National Building Code Standards. The idea for this standard was a result of a group of Concrete Alberta members whose desire it was to reduce Alberta climate extreme field performance issues that are related to inconsistency in concrete composition.

DURA-MIX® assures that your concrete will meet the following minimum standards:

• Minimum Portland cement content 300 kg/m³
• Maximum Water/Cementing Materials Ratio  0.45
• Air Content 5-8%
• Slump 80+/- 30 mm*
• *Superplasticizer (HRWR) may be used to maintain  the quality of the concrete at higher slumps.
