Researchers turned waste eggshells into powder and replaced 10% of cement, producing stronger mortar after 28 days |
Researchers have found that waste eggshells can be processed into a fine powder and used to replace part of the cement in mortar without reducing its compressive strength. A study tested calcined eggshell powder at replacement levels ranging from 2.5% to 12.5%. The strongest result came at 10%, where the mortar reached a compressive strength…
