Water recirculation initiative reuses 88 - 100% of cooling water in cement grinding
In a water conservation move, Panamanian cement producers reused cooling water used in cement grinding at a rate of 88 – 100% nationally in 2020. The development is part of a water conservation effort first launched by Argos Panamá. The Cementos Panamá’s Quebrancha grinding plant is reported to have reduced its water consumption by 88% in five years, to 59,600m3 from 477,000m3 in 2015. The plant’s cement now has a water consumption of 100l/t, compared to 537l/t in 2015.
Murdoch University team develops fly ash-based concrete
Australia: Researchers from Murdoch University in Western Australia have developed a cement-free concrete called Colliecrete. The concrete comprises 80 – 90% of fly ash. Other ingredients are bauxite residue and recycled aggregates. It is said that the customers can make Colliecrete ‘anywhere, at room temperature.’
