石墨尾矿混凝土与钢筋粘结在C60时与普通混凝土基本相当：《科学报告》C40粘结强度低12.93%、C60仅低0.86%，11月13日刊出
《科学报告》于2026年11月13日刊出石墨尾矿混凝土粘结性能与生态特性对比研究。论文由Zeng、Xu、Li等人发表，数字对象标识符为10.1038/s41598-026-76074-y，2026年5月24日收稿、10月12日接受。
研究考察石墨尾矿混凝土用于钢筋混凝土结构的可行性，系统评估其与普通混凝土相比的粘结性能。
结果显示，在粘结性能方面，石墨尾矿混凝土在C40等级与带肋钢筋的粘结强度较普通混凝土下降12.93%，峰值滑移增加39.4%。
当强度等级提高到C60时，两种混凝土的粘结强度基本相当，仅下降0.86%，峰值滑移增幅为61.9%。论文据此指出，高强度基体可有效抑制石墨尾矿带来的负面影响。

Graphite Tailings Concrete Matches Ordinary Concrete on Reinforcement Bond at C60: Bond Strength Was 12.93 Percent Lower at C40 but Only 0.86 Percent Lower at C60 in Scientific Reports, Published November 13
Scientific Reports published a comparative study of the reinforcement bond performance and ecological properties of graphite tailings concrete and ordinary concrete on November 13, 2026. The paper, by Zeng, Xu, Li and co-authors, carries digital object identifier 10.1038/s41598-026-76074-y, was received on May 24, 2026 and accepted on October 12, 2026. The study investigated the feasibility of applying graphite tailings concrete in reinforced concrete structures, systematically evaluating its bond performance against normal concrete. The results indicate that, in terms of bond performance, the bond strength of graphite tailings concrete with ribbed reinforcement at the C40 grade decreased by 12.93 percent compared with normal concrete, while the peak slip increased by 39.4 percent. When the strength grade increased to C60, the bond strength of the two concretes was basically equivalent, with a decrease of only 0.86 percent, and the peak slip increase was 61.9 percent, indicating that a high-strength matrix can effectively suppress the negative effects of graphite tailings.
