Through purchase and lease options, Volvo Trucks North America has secured 270 acres adjacent to its Virginia assembly operations and newly built Customer Center. In the near term, the manufacturer will use 49 acres acquired from Pulaski County to extend its 1.1-mile Customer Experience Track. The remaining land will serve future business expansion.
SOLIDIA SECURES BONDING ELEMENT, METHOD PATENT
The U.S. Patent and Trademark Office has recognized the unique structure of Solidia Technologies’ eponymous concrete, designed and produced with conventional aggregates and processes, but bearing an alternative to hydraulic binders that reacts with carbon dioxide versus water. U.S. Patent No. 9,868,667, “Bonding Element, Bonding Matrix and Composite Material Having the Bonding Element and Method of Manufacturing Thereof,” covers the composition of matter of the distinctive, non-hydraulic, CO2-cured concrete available as Solidia Concrete.
“The hydrate bonds in conventional concrete can compromise that material’s strength and durability,” explains Solidia Chief Technology Officer Nicholas DeCristofaro, Ph.D. “With CO2-cured concrete, bonding elements based on silica and calcium carbonate create a wide range of attractive properties, including mechanical strength, [and] resistance to freeze-thaw deterioration [or] sulfate attack.”

A Rutgers University-patented process to which Piscataway, N.J.-based Solidia Technologies has exclusive rights, starts with an energy-saving, sustainable cement, specification of which equates to a carbon footprint reduction up to 70 percent when measured against conventional portland cement concrete. Using the same raw materials and existing plant equipment, CO2-cured Solidia products and structures are higher performing, cost less to fabricate, and cure in less than 24 hours, company engineers contend.
Currently in commercialization for large- and small-scale applications, the initial technology focus at Solidia’s northern New Jersey headquarters was unreinforced precast and unit masonry. Engineers are now developing commercial processes for reinforced products, including aerated concrete, railroad ties, architectural panels and hollow core plank.
