Mechanical Properties and Durability of CNT Cement Composites
In the present paper, changes in mechanical properties of Portland cement-based mortars due to the addition of carbon nanotubes (CNT) and corrosion of embedded steel rebars in CNT cement pastes are reported. Bending strength, compression strength, porosity and density of mortars were determined and related to the CNT dosages. CNT cement paste specimens were exposed to carbonation and chloride a...
متن کاملEffect of Surfactants on Pressure-Sensitivity of CNT Filled Cement Mortar Composites
*Correspondence: Xun Yu, Department of Mechanical and Energy Engineering, University of North Texas, Denton, TX 76203, USA e-mail: [email protected] Sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (NaDDBS) were used as surfactants to disperse multi-walled carbon nanotubes (MWNT) in cement mortar and fabricate pressure-sensitive carbon nanotubes filled cement mortar composites. The...
متن کاملManufacture of Cnt Reinforced Polymer Composites Using Nanofibers Containing Cnt
Carbon nanotubes (CNTs), discovered by Japanese scientist Sumio Iijima, have outstanding material properties such as mechanical, thermal, electrical, and magnetic properties. For example, CNTs are not only lighter than common irons, but also 100 times stronger than the irons. However, CNTs are so tiny, that is, surface area per volume is relatively large. Consequently, they tend to agglomerate....
متن کاملBiodegradable Poly(butylene succinate) Composites Reinforced by Cotton Fiber with Silane Coupling Agent
In this study, the use of cotton fiber (CF) as a filler in poly(butylene succinate) (PBS) and the effect of silane treatment on the mechanical properties, thermal stability, and biodegradability of PBS/CF composites are investigated. The results showed that the tensile strength of PBS was improved (15%–78%) with the incorporation of CF (10–40 wt%) and was further increased (25%–118%) when CF wa...
متن کاملAbrasion Resistance of Cement-Based Composites
Cement-based composites are among the most widely-used construction materials due to their low cost, high compressive strength, high durability, versatility, and easy-handling. Unfortunately, cement-based composites are intrinsically porous and may deteriorate as a result of exposure to harsh environments or poor construction quality. Over the last few decades, most research has focused on the ...
