New superplasticiser line MC-PowerFlow evo

Technological challenges in concrete development

In almost all ready-mixed concrete and precast concrete plants in Germany, residual concrete and residual water are recovered, processed and reused. Increasingly, legislators are also demanding the use of recycled aggregates, and scientific studies indicate that this trend will gain further traction in the coming decades.

The gradual phase-out of coal-fired power generation in many countries will also lead to a steady decline in the amount of fly ash produced. The availability of primary raw materials such as gravel and sand is also finite. The concrete industry needs to accommodate these changing conditions, adapt to them and find alternative raw materials for concrete production. Plasticisers that also function under these new fundamentals are thus destined to become increasingly important.

Further development of proven PCE polymerisation technology

With its new PCE product generation MC-PowerFlow evo, MC-Bauchemie has launched a range of high-performance superplasticisers onto the market with which the challenges to concrete technology outlined above can be mastered, allowing and indeed ensuring the production of a robust concrete. These are synthetic superplasticisers based on a further development of the proven PCE polymer technology of MC-Bauchemie. They are manufactured in MC’s own production facilities on the basis of a patented process.

Robust, readily workable concretes

The high-performance superplasticisers of the MC-PowerFlow evo line are very well suited to the production of ready-mixed concrete and precast elements, free-flowing and self-compacting concretes, and also to combination with clinker-optimised cements. They can be mixed homogeneously into the concrete in a short time, with dosage after the addition of water generating the greatest efficacy. Their excellent fluidising effect is then immediately unleashed to ensure fast and economical concrete production. Aside from achieving effective and economical adjustment to the target consistency, concrete manufacturers can also be sure of accurate replication time and time again.

Optimised rheological properties with effective consistency control

MC-PowerFlow evo enables significant optimisation of the rheological properties of the concrete. The noticeably reduced tack and viscosity of the concrete results in very good pumpability. The resultant ready-mixed concrete also impresses with excellent placement and compaction properties. The new high-performance superplasticisers thus specifically enhance the energy-optimised production and processing of concrete coupled with high output levels. And because they can also be combined with alternative starting materials such as clinker-optimised binders, recycled material and water or lower-quality raw materials, they also contribute to environmental and climate protection.

Compared to conventional superplasticisers, the new MC-PowerFlow evo generation offers concrete producers better possibilities for effective consistency control, even under difficult conditions, engendering greater reliability in the production of robust and rheologically optimised concretes.
