| description | Abstract 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. |
