Deagglomeration of carbon nanotubes in aqueous solutions of melamineformaldehyde, naphthaleneformaldehyde, lignosulfonate plasticizers

Abstract: Досліджено деагломерацію багатошарових вуглецевих нанотрубок (ВНТ) у водних розчинах меламіноформальдегідного, нафталіноформальдегідного, лігносульфонатного пластифікаторів, що використовуються в будівельних сумішах, та одержано їхні дисперсії різної стабільності. Показано вплив вмісту твердої фази ВНТ на агрегативну стійкість водних суспензій пластифікатор-ВНТ. Стабільними у часі є суспензії на основі розчину меламіноформальдегіду зі вмістом ВНТ 1.0 мас. % та практично стабільні-на основі розчину нафталінофор… Show more

“…The introduction of multilayer carbon nanotubes with a diameter close to the thickness of nano-disperse phase layers C-S-H into no-slump concrete mixtures may have different effects on hardened cement paste properties. [23][24][25][26][27][28] Koward 25 determined an increase in strength when a small number of multilayer nanotubes were introduced into high-quality concrete. However, the number of carbon nanotubes relative to the volume of hardened cement paste is quite small (fraction of per cent), which causes some technological difficulties with their uniform distribution in the cement matrix.…”
