Continuing to improve our concrete recycling system

If every RMC factory is worried about concrete waste, it is even more a concern for companies based in cold places, as for example Hokkaido or Yamagata.

When below 0 degrees concrete won't harden.

It is a big problem for RMC factories.

When this happens returned concrete can't be broken easily.

Also in Izu no Kuni City, home of NR, in cold winters water freeze, especially during the night.

So we needed a solution also for this.

And we found it. We had to found it, also because Re-Con Zero/IWA aggregates are mostly used and requested during winter time. This is due to the easy handling of ECON (IWA recycled concrete) during winter. Even easier than normal concrete, as it hardens faster.

By putting those lights on during the night the water contained in the sludge won't freeze and will continue to flow out of the fence, leaving just the solid part of the sludge inside. Those sludge will then be mixed with remaining/returned concrete and IWA/RCZ powder the day after.

Re-Con Zero powder makes the RMC factories work really easier.

Instead of letting returned concrete harden and then break it, in 10 minutes it can be easily treated by using a normal excavator.

Will continue also this year to promote and improve our IWA System!
