Further, natural aggregate, ferro slag, and duration of curing were considered as basic variables to suggest the model. Regression models for response data were evaluated using analysis of variance (ANOVA) and Pareto charts. The results show that the mix MF30 (30% substitution of natural aggregate by ferro slag aggregate) had higher compressive strength. The residual compressive strength at 270 days under alternate wetting and drying, acid attack, and sulphate attack was obtained as 62 MPa, 62.50 MPa, and 66.50 MPa, respectively. Similarly, the percentage loss of weight was obtained as 12.92%, 12.22%, and 6.60% for alternate wetting and drying, acid attack, and sulphate attack, respectively. The findings of the analysis of variance (ANOVA) indicate that the most significant factors influencing the variables C 年代 W D , C 年代 一个 T , 和 C 年代 年代 T 是天然骨料、铁渣和养护期。的回归模型 C 年代 W D , C 年代 一个 T , 和 C 年代 年代 T 是非常重要的,通过方差分析和帕累托图分析如图所示。SN - 1687 - 8086 UR - https://doi.org/10.1155/2023/9960412 - 10.1155 / 2023/9960412摩根富林明土木工程的进步PB - Hindawi KW - ER
