对掺入预选粗集料的超高性能混凝土(UHPC)的耐磨性进行了试验研究。骨料是根据它们的属性和本地可用性来选择的。此外，煤底灰粉还与较粗集料一起用作硅粉的替代品。根据ASTM C 944试验方法进行检查，并以质量损失和磨损深度表示结果。试验结果表明，超高性能混凝土具有良好的耐磨性，但与不含粗集料的超高性能混凝土相比，集料较粗的超高性能混凝土的耐磨性较差。(C)2018爱思唯尔有限公司。保留所有权利。
This experimental study was conducted to evaluate the abrasion resistance of ultra high performance concrete (UHPC) that incorporated pre-selected coarser aggregates. The aggregates were selected based on their properties and local availability. In addition, coal bottom ash powder was also used with coarser aggregates as a replacement for silica powder. The examination was made according to the ASTM C 944 test method and the results were determined and presented as mass loss and depth of abrasion. All the results from the tests reveal the excellent abrasion resistance of UHPC; however, when compared to each other, the UHPC with coarser aggregates shows a lower abrasion resistance than the UHPC with no coarser aggregates.
