Due to increased industrialization, large amount of industrial by-products are produced every year in all parts of the world. Disposal of these often toxic wastes is the major problem faced and can potentially be solved by their use in the construction industry. The main aim of this study was to utilize the argon oxygen decarburization (AOD) steel slag (a waste product from the stainless steel industry) in the concrete mix for construction of rigid pavements. The present study evaluated various properties of concrete mixes containing 0–25% of AOD steel slag as a partial replacement of ordinary portland cement and further curing the mixes for 28, 90, 180 and 365 days. Thus, the study investigated the compressive and flexural strengths, abrasion resistance, resistance to acid attack and resistance to sulfate attack of concrete mixes. Further, scanning electron microscope, energy-dispersive X-ray spectroscopy and toxicity characteristic leaching potential (TCLP) analyses were also conducted to study the micro-structural properties and leaching characteristics of steel slag mixed concrete. Compressive and flexural strength showed the positive results as the curing period of the specimens increased. Durability properties were less affected by the addition of AOD steel slag. TCLP analysis revealed that the toxicity of steel slag concrete was found within the permissible limits as compared to the raw steel slag. Further, to approximate the underlying relationship existing between the input–output data, a Legendre functional link neural network has been implemented for the prediction of compressive and flexural strengths.

由于工业化程度的提高，世界各地每年都会产生大量的工业副产品。处理这些经常有毒的废物是面临的主要问题，可以通过在建筑业中使用这些废物来解决。这项研究的主要目的是在混凝土混合料中利用氩氧脱碳（AOD）钢渣（不锈钢行业的废品）来建造刚性路面。本研究评估了含0-25％AOD钢渣的混凝土混合物的各种性能，以部分替代普通硅酸盐水泥，并进一步固化该混合物28、90、180和365天。因此，研究调查了混凝土混合物的抗压强度和抗折强度，耐磨性，耐酸侵蚀性和抗硫酸盐侵蚀性。进一步，还进行了扫描电子显微镜，能量色散X射线能谱和毒性特征浸出电位（TCLP）分析，研究了钢渣混合混凝土的微观结构和浸出特性。抗压强度和抗弯强度随着样品固化时间的延长而显示出积极的结果。添加AOD钢渣对耐久性能的影响较小。TCLP分析表明，与钢渣相比，钢渣混凝土的毒性在允许的范围内。此外，为了近似输入输出数据之间存在的潜在关系，已实现了勒让德功能链接神经网络，用于预测抗压强度和抗弯强度。还进行了能量色散X射线光谱分析和毒性特征浸出潜力（TCLP）分析，以研究钢渣混合混凝土的微观结构特性和浸出特性。抗压强度和抗弯强度随着样品固化时间的延长而显示出积极的结果。添加AOD钢渣对耐久性能的影响较小。TCLP分析表明，与钢渣相比，钢渣混凝土的毒性在允许的范围内。此外，为了近似输入输出数据之间存在的潜在关系，已实现了勒让德功能链接神经网络，用于预测抗压强度和抗弯强度。还进行了能量色散X射线光谱和毒性特征浸出潜能（TCLP）分析，以研究钢渣混合混凝土的微观结构特性和浸出特性。抗压强度和抗弯强度随着样品固化时间的延长而显示出积极的结果。添加AOD钢渣对耐久性能的影响较小。TCLP分析表明，与钢渣相比，钢渣混凝土的毒性在允许的范围内。此外，为了近似输入输出数据之间存在的潜在关系，已实现了勒让德功能链接神经网络，用于预测抗压强度和抗弯强度。
