Evaluating the Effect of Calcination and Grinding of Corn Stalk Ash on Pozzolanic Potential for Sustainable Cement-Based Materials

open access: yesAdvances in Materials Science and Engineering, 2020
In developing countries, one of the usual practices is the uncontrolled, open burning of corn stalk (CS) or its utilization as a fuel. It is known that the ash obtained under uncontrolled burning conditions constitutes blackish and unburnt carbon ...

Effect of Al2O3 on the Structural Properties of Water-Quenched Copper Slag Related to Pozzolanic Activity

open access: yes, 2023
Water-quenched copper slag (WCS) modified with alumina (Al2O3) has been proven as a cement substitute; however, the effect of Al2O3 on structural properties of WCS related to pozzolanic activity has not been well investigated.
