Working principles in comparison
High number of mixing tools… higher wear…
… and plenty of room for material accumulations
� Severe wear
� This often requiresceramic linings
� Disadvantage: Costly and lengthystoppages forrenewing the lining

Typical precast plantTypical precast plant
Advantages of EIRICH preparation solutions
400 m³ per day → 120.000 m³ per year (300 days)
Assuming cement savings of only 10% results in:
→ approx. 50 kg less cement per m³ concrete
→ means total cement savings of 6.000 t / year
→ with a cement price of 1 Million Rupiah per ton
the saving in cement costs per year is worth
6 Billion Rupiah / year (450.000 USD / year)

Advantages of EIRICH preparation solutions
This calculation does not take into account the additional costs of reject losses, disposing of the rejects and supplying replacement products.
The difference in price for the EIRICH mixing solutions pay back within months!

Innovations
„New“ concrete materials
� Self-compacting concrete (SCC):
SCC for short, compaction without vibration, using suitable recipes or admixtures
� High-performance and ultrahigh-performance concrete (HPC & UHPC):
HPC / UHPC for short, cement with high compressive strength, high-performance liquefier, possibly fine additives (microsilica). Often very fluid, little maximum-size grain
� Translucent concrete:
Optical fibers are added (3-5% glass fiber) to make the concrete translucent
� Self-cleaning concrete:
Superhydrophobic or superhydrophilic (similar to lotus effect),through adding admixtures to the mixing process….
� Fiber, Polymere & Colour concrete

Summary of EIRICH mixing process advantagesSummary of EIRICH mixing process advantages
Advantages of EIRICH preparation solutions
� Much higher homogeneity of the mixturedue to better material flow with rotating mixing pan
� Through perfect dispersion, 5 - 15% of cement can be saved.
� High mixing qualities obtained in shortest mixing timeand higher throughput rates
� Quickly obtained stable moisture measurement
� Water distributed more effectively
� Consumption of binders, pigments and chemicalscan usually be reduced by up to 15%
� Significant lower wear and maintenance costsand therefore higher availability of the plant
� Reject rates much lower, particularly for visible surfaces errors
� Only 1 (2) mixing tool(s) for mixer sizes up to 4,000 liters
