Coal ash recycling at record rate, lower concrete market metric aside

The American Coal Ash Association Production and Use Survey, released late last month, pegs 2016 Class F and Class C fly ash consumption in concrete at 14.4 million tons, down 8 percent from the prior year’s record 15.7 million tons. ACAA attributes the dip to regional supply shortages that resulted from power plant shutdowns and generating stations’ changing fuel profiles. Demand for fly ash remained strong across all concrete markets last year, the group affirms, and utilization likely would have been higher absent logistical disruptions.

LafargeHolcim meters solar film-faced UHPC cladding wattage

A two-year collaboration between LafargeHolcim Ltd. and Dresden, Germany-based Heliatek GmbH has netted a photovoltaic concrete façade product capable of generating double the amount of energy typical of roof-based solar panel arrays. At 60 percent of the exterior, the cladding has the potential to generate 30 percent of a 10-story building’s annual energy requirements. Unveiled at Batimat 2017 in Paris, it combines LafargeHolcim’s Ductal ultra-high performance concrete, suited to architectural applications in ½-in. or greater thickness; and, Heliatek’s flexible, ultra-light HeliaFilm, weighing 1 kilogram/square meter (2.2 lbs./10.75 sq. ft.) and produced in shades of blue, gray and green.
