| 摘 要： | 为了满足严寒地区水利工程的抗冲磨要求,开展了掺加引气剂、HF抗冲磨剂等外加剂,研究了水胶比、粉煤灰掺量、HF抗冲磨剂掺量对高性能混凝土抗冲磨性能的影响,以期为今后的类似工程提供一定的参考价值。研究表明：粉煤灰掺量在15%～25%时,高性能混凝土的抗冲磨强度变化趋势是先升后降,说明掺入适量的粉煤灰是可以提高抗冲磨强度的;HF抗冲磨剂能显著提高高性能混凝土的抗冲磨性能,但掺量并不是越大越好,有一个最优掺量;混凝土的抗冲磨强度随着水胶比的降低而增大,但水胶比若过小,则抗冲磨强度反而会降低。

| Abstract: | In order to meet the requirements of hydraulic engineering abrasion resistance in cold areas,the effects of fly ash,water-cement radio and HF content on the abrasion-erosion resistance of high performance concrete(HPC) are studied in this paper.The results show that: when fly ash content is between15% and 25%,the abrasion strength of HPC trend decreases sooner or later;HF abrasion agent can significantly improve the abrasion resistance of HPC,but that does not mean the greater the volume,the better,there is... |
