Why is supplementary cementitious material in concrete?
Score: /5 (10 votes) . Supplementary Cementitious Materials (SCM''s) are added to concrete mixtures for various reasons including improving durability, decreasing permeability, aiding in pumpability and finishability, mitigating alkali reactivity and improving the overall hardened properties of concrete through hydraulic or pozzolanic

Nonetheless, the natural carbonation method alters the microstructure of hardened cement pastes and degrades the physical and mechanical properties of concrete [18,19,20]. The sealing alkali method using epoxy resin to cover porous concrete materials also shows the disadvantages of strong toxicity and high cost. Thus, the aforementioned
