Graphene nanoplatelets (GNPs) have the same chemical structures as carbon nanotubes but their internal structure consists of multiple layers graphene with thicknesses only a few nanometers. Compared to nanotubes, GNPs are less prone agglomeration and entanglement when they used nanofillers in composite materials. This paper investigates development self-sensing cement composites using simple fabrication method that does not require special preparation procedures such ultrasonication...
Over the past two decades, numerous research studies have been conducted to explore behavior of self-sensing cementitious composites with different functional fillers. Most these investigated use fillers such as carbon nanofiber (CNF), black, and nanotubes (CNTs) in cement develop a multifunctional material. Since its discovery 2004, graphene has also raised significant attention 2D nanoscale reinforcement for composite materials. The planar structure sheets provides more contact area host...
Abstract Over the past decades, a number of structural health monitoring methods have been developed for condition assessment concrete structures. Most these require installation external sensors. Accelerometers are commonly used vibration-based damage detection entire structure, while strain gauges installed in order to detect cracking and at component level. Conventional sensors, such as metal foil gauges, widely monitor local conditions However, all sensors certain shortcomings exhibiting...
Despite being most widely used construction materials, cement-based composites are brittle materials with low tensile strength and susceptible to cracking, especially under harsh environments. Over the past three decades, numerous studies have been conducted enhance mechanical properties durability of cementitious through use various nanomaterials such as carbon nanotubes (CNTs) nanofibers (CNFs). More recently, graphene nanoplatelets (GNPs) has emerged an ideal 2D nano-reinforcement for...
The cement-based additive manufacturing, commonly known as 3D concrete printing, facilitates the use of advanced cementitious materials in construction this technique minimizes waste and enables optimal placement material. printable mixtures should have specific consistency for successful manufacturing. In particular, they be extruded smoothly during printing process while maintain their shape after deposition, both which are closely related to rheological properties mixture. graphene...
Graphene nanoplatelets (GNPs) have the same chemical structures as carbon nanotubes but their internal structure consists of multiple layers graphene with thicknesses only a few nanometers. Due to increased thickness, GNPs are less prone agglomeration and entanglement when they used nanofillers in composite materials. Although it has been shown that self-sensing cementitious composites can be fabricated using GNPs, further studies needed reveal effect various factors on performance such...
