Dry cements (IMAGE)
Caption
A comparison of recycled cement by itself (left), ordinary Portland cement (middle), and the researchers’ optimized blend of recycled cement and finely ground Portland cement (right), before the addition of water. The optimized cement blend demonstrates similar water requirements, strength gain, and workability to ordinary Portland cement while generating a fraction of the carbon emissions.
