Employing a factorial quasi-experimental design, four CRH and eggshell ratios were tested across three curing periods. Twenty-four concrete samples were prepared, with 12 for compressive strength and weight assessment using ASTM cylinders (4x8 inches), and 12 for water absorption evaluation. In the results of the study, the data was analyzed through a One-way ANOVA statistical test. It revealed that there was no significant difference between the concrete samples with different ratios and different curing periods on their compressive strength, water absorption, and weight. However, there was a significant difference with the different curing periods and water absorption. Statistical analysis indicated no significant difference in compressive strength, water absorption capacity, or weight between concrete samples grouped by replacement ratios, while a significant difference was observed in water absorption capacity across different curing periods. To conclude, concrete samples with higher replacement ratios tended to exhibit lower compressive strength and higher water absorption rates. However, longer curing periods generally led to reduced water absorption, indicating potential for improved durability.| Item type | Current location | Home library | Collection | Call number | Copy number | Status | Date due | Barcode | Item holds |
