چکیده
Abstract This study is aimed to investigate the effect of carbon nanotubes on properties lightweight aggregate concrete containing expanded glass and silica aerogel. Combinations (55%) hydrophobic aerogel particles (45%) were used as aggregates. Carbon sonicated in water with polycarboxylate superplasticizer by ultrasonication energy for 3 min. Study results show that incorporating multi-wall significantly influences compressive strength microstructural performance based concrete. The addition gained almost 41% improvement strength. SEM image shows a homogeneous dispersal within structure. composite presence C–S–H gel surrounding nanotubes, which confirms cites higher growth gel. Besides, agglomeration ettringites was observed transition zone between cementitious materials. Additionally, flowability, absorption, microscopy, X-ray powder diffraction, semi-adiabatic calorimetry analyzed this study.
