Reducing Cement Content in Concrete Mixtures. Putting Research to Work Brief
Concrete mixtures contain crushed rock or gravel, and sand, bound together by Portland cement in combination with supplemental cementitious materials (SCMs), which harden through a chemical reaction with water. Portland cement is the most costly component of concrete mixtures, and its production creates significant amounts of green house gases. To reduce costs and environmental impacts, current WisDOT practice allows a for replacement of a portion of Portland cement supplemental cementitious materials (SCMs) such as coal fly ash or slag cement, both industrial by-products of coal and iron production, respectively. WisDOT has set a maximum limit on Portland cement replacement through use of SCMs to ensure its performance on concrete pavements.
