High Concrete Group is starting an $8 million expansion of its Denver plant that could create 50 to 70 jobs, the company announced Wednesday.
High Concrete president John “J.” Seroky said the year-long project, which he described as a manufacturing “revitalization,” will help it meet growing demand for its architectural precast concrete.
Seroky said the expansion will boost High Concrete’s architectural-precast manufacturing capacity and efficiency, lower the site’s carbon footprint and improve working conditions.
EcoMix is a precast concrete mix that reduces carbon dioxide from conventional cement by at least 50%. EcoMix allows architects and designers to improve key sustainable attributes of their buildings and lower the overall carbon footprint of their precast projects.
Prior to EcoMix, typical High Concrete Group precast concrete contained approximately 10% Portland cement. The company targeted this ingredient for reduction as part of the High Commitment to Sustainability. According to the Portland Cement Association, the production of Portland cement contributes about 5% of human-produced greenhouse gas emissions worldwide.
High uses supplementary cementitious materials (SCMs) to replace half or more of the Portland cement in its precast concrete. The SCMs include ground granulated blast furnace slag, fly ash and silica fume that are derived from industrial waste stream products. The materials may be used individually or as a blend, and can improve the light reflectance, workability and other characteristics of precast concrete.
The use of EcoMix is currently limited to High’s full-line plant in Denver, Pa. EcoMix joins High’s ECastTM and CarbonCast® brands of more sustainable precast concrete that helps improve the carbon footprint of building projects by reducing embodied energy.
