Structural Performance of CNT-Reinforced Cementitious Materials Considering the Effect of Chirality of Nanotubes

Foad Mohajeri Nav et al.

Summary: This study investigates the effects of different chirality carbon nanotubes (CNTs) on the engineering behavior of cement-based composites. The results show that composites modified by chiral CNTs demonstrate great structural enhancement, while armchair-modified composites lead to undesirable strength development.

Application of experimental and statistical methods in the study of rheology of MWCNT (25%)-TiO2 (75%)/SAE40 HNF to identify and use in the lubrication industry

Mohammad Hemmat Esfe et al.

Summary: The viscosity behavior of MWCNT-TiO2/SAE40 combined nanofluid was studied using experimental and statistical methods. The results showed that the viscosity of the nanofluid was influenced by the solid volume fraction, temperature, and shear rate. The response surface methodology was used to predict the experimental results and establish a mathematical relationship.

Enhanced microstructural characteristics of binary and ternary blended cements reinforced with graphene oxide

Karthik Chintalapudi et al.

Summary: The utilization of alternative binders such as high-volume fly ash and ternary blended silica fume in cement composites can effectively reduce global carbon emissions. This article discusses how the addition of nanomaterials like graphene oxide (GO) enhances the efficiency and early strength of these cement composites. The study reveals that GO promotes early strength and improves the microstructural properties of cement composites, making it a potential solution for sustainable construction.

Experimental study on physical and mechanical properties and micro mechanism of carbon nanotubes cement-based composites

Guifeng Liu et al.

Summary: The effects of MWCNTs content, water cement ratio, and addition method on the mechanical properties and microstructure of cement-based composites were studied. It was found that the flexural and compressive strength of the composites first increased and then decreased with the increase of MWCNTs content. MWCNTs played a bridging and filling role in the matrix.

Electromagnetic wave absorption properties of MWCNTs-COOH/cement composites with different shapes of chiral, armchair and zigzag

Mahsa Fakharpour et al.

Summary: In this study, the electromagnetic wave absorption performances and dielectric properties of multi-walled carbon nanotube (MWCNT) functionalized with carboxyl (-COOH) group/cement composites with different shapes were investigated. The influence of sample thickness and MWCNT shape on the electromagnetic wave reflection loss, insertion loss, and absorption in the frequency range of 8-12 GHz was studied. Experimental results showed that MWCNT/cement composites have higher absorption properties at frequencies below 10-10.5 GHz compared to control samples, with absorption behavior varying with sample thickness and MWCNT shape.

Enhanced thermoelectric properties of cement-based composites by Cl2/HNO3 pretreatment of graphene

Zhaoyang Jia et al.

Summary: Cement-based composites with thermoelectric effect show potential in addressing urban heat island effect, snow and ice melting on winter roads, and energy conversion and harvesting. Pretreatment of reduced graphene oxide (RGO) with Cl-2 can enhance both the electrical conductivity and Seebeck coefficient of cement-based composites, leading to improved thermoelectric properties. The optimal performance is achieved with 5.0wt% Cl-2 pretreated RGO in cement-based composites.
