Abstract

This paper presents first results of the study of the resistance of carbon nanotube concrete composite (CNT/concrete composite) to the action of continuous and pulsating water jets. The experiments oriented at the determination of erosion effects of pulsating and continuous water jets impinging the surface of reference (concrete) and CNT/concrete composite samples were performed. Tested samples were characterized by X-ray powder diffraction and scanning electron microscope. Samples were exposed to pulsating and continuous water jets at various operating parameters. Erosion effects of pulsating and continuous jets were evaluated in terms of material removal rate. The possible influence of addition of CNTs to the concrete on its resistance to the action of continuous and pulsating water jets is discussed in the paper. The experiments proved that CNT/concrete composite exhibits higher resistance than reference concrete to the action of both pulsating and continuous water jet under the given testing conditions.

连续和脉动水射流对碳纳米管/混凝土复合材料的影响

本文介绍了碳纳米管混凝土复合材料(CNT/混凝土复合材料)对连续和脉动水射流的阻力研究的初步结果。针对脉动和连续水射流冲击参考(混凝土)和碳纳米管/混凝土复合材料样品表面的侵蚀效果进行了实验研究。用x射线粉末衍射和扫描电镜对样品进行了表征。在不同的操作参数下，将样品暴露在脉动和连续的水射流中。从材料去除率方面对脉动射流和连续射流的侵蚀效果进行了评价。本文讨论了在混凝土中加入碳纳米管对混凝土抗连续和脉动水射流作用的可能影响。实验证明，在给定的试验条件下，CNT/混凝土复合材料对脉动水射流和连续水射流的阻力均高于参考混凝土。
