プレキャストコンクリート
The intent to open a concrete products industrial park north of Cananea was announced in January 2018 by Ing. Glenn Edward Roy E. of "Ferrocret", a conglomerate that shall produce all manner of precast concrete products such as: hydro conduit; walls, floors, and ceilings of affordable housing; drycast concrete pavers; cinder block; concrete railway sleepers. The factories will utilise proprietary fast-cure concrete formulations in combination with the abundant nearly free-of-cost copper slag "escoria"—an aggregate alternative to expensive riverbed-mined gravel. Over one hundred years of mining activities at Cananea have generated huge manmade mountains of copper slag... thereby providing an ideal, low-cost alternative for supplying graded aggregates for inclusion within those various precast concrete products. Precast concrete products manufacturing promises to become a major industry in the region, and one which shall lessen the dependence of the Cananea job force on a local economy that historically solely has been dependent upon the mines remaining open.
