2021-11-19 Vulnerability to atmospheric carbonation is one of the major durability concerns for limestone calcined clay cement (LC3) concrete due to its relatively low overall alkalinity. In this study, the natural carbonation behaviors of ternary ordinary Portland cement-metakaolin-limestone (OPC-MK-LS) blends containing various sulfate salts (i.e., anhydrous CaSO4, Na2SO4, and K2SO4) are studied,

Dozens of variables come into play in the cement production process, from the quali-ty of the limestone and the coal’s chemical properties to the type of fuel in the kiln and the desired quality and cost of the end product. Most cement players work to opti-mize these variables at each step in the
