Quality & Norms
Raw Material are produced from qualified sources. The following tests on aggregates are preformed to guarantee consistency of concerte mixed.
- Sieve anaylsis - ASTM C136, performed daily.
- Absorpition and specific gravity - ASTM C127 and C128, performed once per week
- The Moisture content of aggregates is measured by the mixer controller in order to make proper adjustments in mixing water automatically.
