    Effect of Calcined Marble Powder and Magnetized Water on the Performance of Cement-Based Composites by Erdinc Halis Alakara, Ozer Sevim, Gazi Günel, İlhami Demir

    Published 2024-12-01
    “…Notably, CMP-substituted mortars produced with TW showed a 10.8% to 15.8% increase in 28-day <i>f<sub>cs</sub></i> values compared to RMP-substituted mortars, while those prepared with MW exhibited 7.8% to 10.9% higher <i>f<sub>cs</sub></i> values than TW-prepared samples. A microstructural analysis via SEM indicated that CMP enhances hydration and microstructure densification, resulting in improved mechanical performance and durability. …”
