Effect of molybdenum tailings aggregate on mechanical properties of engineered cementitious composites and stirrup-confined ECC stub columns

Reviews on Advanced Materials Science, 2023
Engineered cementitious composites (ECC) exhibit behaviors of multiple cracking and strain-hardening compared to ordinary concrete. However, the use of ultrafine silica sand (S) to produce ECC results in increased cost and environmental overload.
