Sustainability specialist economizes plant-specific LCA, EPD preparation
A catalyst behind much of the environmental impacts in concrete production database, the Athena Sustainable Materials Institute has released an online calculator affording ready mixed producers instant Life Cycle Assessment and Environmental Product Declaration figures for any mix, easing preparation of full LCA and EPD reports for green building certification candidate projects.
Quality control specialist applies 3D imaging to concrete masonry
A developer of real time inspection tools for a range of production processes timed commercial launch of the HVD (Height Volume Density) Control System for concrete brick, block and pavers with the National Concrete Masonry Association’s 2016 ICON-Xchange in Orlando. The announcement follows Neoculus Technologies’ piloting of the equipment with Oldcastle Architectural’s Quebec-based Permacon business.
MIT researchers: New microstructure modeling spells better concrete
To further understand concrete’s microscopic structure and behavior, researchers from the Massachusetts Institute of Technology, Georgetown University, France’s CNRS and peer institutions on both sides of the Atlantic have focused on the principal binder: Is calcium silicate hydrate a continuous solid, like metal or stone, or an aggregate of small particles? Their finding that solidified CSH is a “bit of both” could inform new approaches to lowering mix designs’ water volume and finished structures’ permeability.
Headwaters Block Group prepares to integrate fly ash-based CalStar process
Headwaters Inc. has acquired the fly ash-centered technology of recently liquidated brick, paver and masonry trim operator CalStar Products.

North American properties top performers in LafargeHolcim charter year
With $5.84 billion in cement, aggregate and ready mixed concrete sales, North America led five LafargeHolcim Ltd. regions in 2015, besting overall figures from Asia Pacific, Europe, Latin America and Middle East Africa businesses. In its inaugural annual report, the company credits continuing U.S. recovery, cost optimization and price management for solid North America region results. Cement and aggregate volumes increased as a whole across the U.S. and eastern Canada, offset partially by a) reduced demand in Texas and western Canada markets, where oil and commodity investments were under pressure; and, b) merger-driven divestments in some states. A double-digit increase in U.S. operating EBITDA (earnings before interest, taxes, depreciation, amortization) stemmed from active cost, price and margin management.Read More
