The objective of this scholarly endeavor is to engineer an innovative, eco-friendly construction material, specifically straw fiber steel slag foam concrete (SFSSFC), with the dual purpose of optimizing resource utilization and mitigating energy expenditure within the construction sector. Through meticulous manipulation of the constituent ratios of steel slag powder, straw fiber, and foam, a series of 15 SFSSFC specimens were fabricated. Subsequent to their preparation, a comprehensive evaluation was conducted to ascertain their fluidity, water absorption, mechanical strength, thermal conductivity, and resistance to freeze-thaw cycling. The findings revealed that an increment in foam content correlates with enhanced fluidity and water absorption characteristics of the concrete matrix. Furthermore, it was determined that a 15% steel slag powder content yielded the most favorable mechanical strength outcomes. Notably, specimens incorporating 3% straw fiber displayed the lowest thermal conductivity among the evaluated samples. In assessing durability, the F10, F15, S15, and C3.0 specimens demonstrated exceptional resilience, enduring 50 cycles of freeze-thaw exposure without incurring damage. Comparative analysis with extant literature suggests that the SFSSFC developed in this study exhibits superior thermal and mechanical properties.
这项学术研究的目标是设计一种创新的、环保的建筑材料，即秸秆纤维钢渣泡沫混凝土（SFSSFC），其双重目的是优化建筑行业的资源利用并减少能源消耗。通过精心控制钢渣粉、秸秆纤维和泡沫的组成比例，制备了15个SFSSFC试件。制备完成后，进行了全面评估，以确定其流动性、吸水性、机械强度、导热系数和抗冻融循环性能。研究结果表明，泡沫含量的增加与混凝土基体流动性和吸水性的增强相关。此外，确定钢渣粉含量为15%时，机械强度结果最为理想。值得注意的是，在评估样本中，掺入3%秸秆纤维的试件导热系数最低。在耐久性评估中，F10、F15、S15和C3.0试件表现出卓越的韧性，经受50次冻融循环而未受损。与现有文献的对比分析表明，本研究中开发的SFSSFC具有优异的热性能和机械性能。
