RE-CON ZERO EVO

Two-component powder product used for returned concrete recovery from mixer trucks.


WHERE TO USE

Recovering all types of concrete returned to mixing plants (including concrete for shotcrete) at the end of each day or when sites are decommissioned.


TECHNICAL CHARACTERISTICS

Re-Con Zero Evo is a two-component powder product made from special polymers and inorganic composites according to a formula developed in the MAPEI research laboratories which allows concrete returned to mixing plants to be completely and quickly recovered directly from mixer trucks. Re-Con Zero Evo transforms returned concrete into an aggregate that, once cured, may be used as follows:

▪ to partially replace natural aggregates for normal concrete;

▪ to completely replace natural aggregates for lean concrete, substrates, mixed cements, etc.

Aggregates produced with Re-Con Zero Evo are considered reclaimed aggregates in accordance with Article 5.2.3.3 of EN 206 (Re-Con Zero aggregates have obtained the DIBt certification no. Z-3.210-2153). Treating concrete with Re-Con Zero Evo does not generate waste or by-products, such as rinsing water or fines, because the process allows the cementitious conglomerate to be completely recovered. After treating concrete with Re-Con Zero Evo, the inside of the mixing drum is extremely clean and considerably less rinsing water is required compared with the amount normally used for cleaning mixing drums at the end of the day.


CONSUMPTION

Re-Con Zero Evo Part A: one 0.5 kg bag per cubic metre of concrete to be treated.

Re-Con Zero Evo Part B: one 1.5 kg bag per cubic metre of concrete to be treated.

Re-Con Zero Booster: one 0.5 kg bag per cubic metre of concrete to be treated.

The recommended dose may be optimised by carrying out specific tests on site and with the assistance of our MAPEI technicians.

PACKAGING

Re-Con Zero Evo is available in plastic bucket, each containing doses for 6 cubic metres of returned concrete to treat:

▪ 0.5 kg six packs of Re-Con Zero Evo Part A (blue bag).

▪ 1.5 kg six packs of Re-Con Zero Evo Part B (transparent bag).

Re-Con Zero Booster is available in carton boxes containing 30 water-soluble blue bags, 0.5 kg each.
