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
