Moving towards the future

The Re-Con Line from Mapei helps concrete producers to make the move towards a more circular and effective production model by offering cost effective and sustainable solutions. Under the four key words of Reclaim, Clean, Recycle and Recarbonate substantial savings in waste handling costs can be made through transformation of returned concrete and truck washing slurry into value material.
Re-Con Line also offers products that enhances circularity of material flows by reducing the need for high cost virgin raw materials by mitigating problems of using recycled concrete, manufactured sand or clay contaminated sand in new concrete.

Sustainable concrete production from linear to circular material flows

Reclaim

Transforms returned concrete into reclaimed aggregates

2-component system of superabsorbent polymer and hardener.
Transforms fresh returned concrete to a granular material by chemically binding of the free water (Part A) and stabilizing and accelerating the process (Part B).

Reducing the environmental impact of concrete production

• Transforming waste stream to resource material

• Increasing material circularity

Reclaimed aggregates achieved without crushing

Method to reduce truck washing slurry

After Re-Con Dry Washing, truck washout can be done with much less water. The water will contain 70% less slurry fines and have a lower pH and reduced heavy metal pollution due to the cementitious residue having been absorbed by the Re-Con Dry Washing aggregates.
Note that even when using a wet process concrete reclaiming system, slurry still needs to be filtered away from the washing water.
This is not the case for Re-Con Dry Washing.
