... properties. Sometimes these changes can lead to strength retrogression of cement. Recently, it was found that calcined clay (CC) and nanoclay (NC) significantly improve the hardened cement matrix properties as both materials have pozzolanic properties. Both additives have characteristics such as acid and...
