摘要

研究了植物油和钢渣骨料对钢渣基碱活化材料干燥收缩和碳化性能的影响。由于金属皂相的形成,碳化率降低了19%,这大大降低了凝胶和小毛细管孔隙率以及材料的比表面积。当与钢渣骨料结合使用时,碳化率可进一步降低50%。此外,收缩和再润湿引起的应变受到所使用的骨料类型的高度影响,由于在金属碱性条件下油水解产生的肥皂相的存在,观察到减少了40 - 50%。观察到的耐久性性能的改善可能为碱活性材料提供新的应用可能性,克服众所周知的技术限制,如高干燥收缩率和高碳化率。

Drying shrinkage and carbonation of steel slag-metakaolin alkali-activated composites: Effect of vegetable oil addition and slag aggregates
The influence of vegetable oil and steel slag aggregates on the drying shrinkage and carbonation performance of steel slag-based alkali activated materials was investigated. Decrease in carbonation rates by up to 19% attributed to the formation of metal soap phases which strongly reduced the gel and small capillary porosity as well as the specific surface area of the materials. When combined with steel slag aggregates, an additional reduction in carbonation rate of up to 50% could be achieved. Furthermore, the strain induced by shrinkage and rewetting was highly influenced by the type of aggregate used, with a reduction of 40 to 50% observed due to presence of soap phases resulting from the hydrolysis of oil in the metal-alkaline conditions. The observed improvement in durability properties may enable new application possibilities for alkali activated materials, overcoming well-known technical limitations such as high drying shrinkage and high carbonation rates.
