Quality concrete of any grade and consistency range, concrete with special characteristics (e.g. water impermeable concrete), pumped concrete, material cost optimization for production of low cost quality concrete. High increase of consistency and/or w/c-reduction, gives homogeneous concrete with good workability.

Manufacture of nearly poreless concrete components, In particular with washed, blasted, polished, tumbled or acidified surfaces, such as panels, steps, troughs, components for street furniture, concrete with high exposed concrete quality, strongly pigmented concrete mixes, concrete with a tendency for intensified pore and foam formation on the fill-in side. Improved exposed concrete quality, increased resistance against damaging environmental influences, reduced tendency of efflorescence, lower soiling tendency.
