Abstract

The problem of increasing of the strength of concretes by means of using suspension based on nanomodified additives with boehmite, graphene and carbon nanotubes is considered. Suspensions were primarily subjected to ultrajet processing. Nano-containing suspensions were studied before and after processing by the indicated method using a Microtrac Bluewave laser analyzer of particle sizes. The analysis provided average particle sizes by quantitative and volume distribution, as well as minimal registered size of particles in the samples. The results of compression strength tests of a batch of concrete samples are presented. It was shown that the use of nanomodified additives leads to an increase in the strength of concrete. It was concluded that investigations must be continued in order to obtain a larger amount of experimental data for statistical processing.

通过 Ultrajet 技术处理的悬浮液对混凝土的纳米改性

摘要

考虑了通过使用基于纳米改性添加剂与勃姆石、石墨烯和碳纳米管的悬浮液来增加混凝土强度的问题。悬浮液主要经过 Ultrajet 处理。在通过指定方法使用粒度的 Microtrac Bluewave 激光分析仪处理之前和之后研究含纳米悬浮液。该分析通过定量和体积分布提供了平均粒径，以及样品中颗粒的最小记录尺寸。介绍了一批混凝土样品的抗压强度试验结果。结果表明，使用纳米改性添加剂可以提高混凝土的强度。
