Flexural strength of concrete is an important property, especially for pavements. Concrete with higher flexural strength has fewer cracking and durability issues. Researchers use different materials, including fibers, polymers, and admixtures, to increase the flexural strength of concrete. silicon carbide and tungsten carbide are some of the hardest materials on earth. In this research, the mechanical properties of carbide concrete composites were investigated. The silicon carbide and tungsten carbide at different percentages (1%, 2%, 3%, and 4%) by weight of cement along with hybrid silicon carbide and tungsten carbide (2% and 4%) were used to produce eleven mixes of concrete composites. The mechanical tests, including a compressive strength test and flexural strength test, along with the rapid chloride permeability test (RCPT), were conducted. It was concluded that mechanical properties were enhanced by increasing the percentages of both individual and hybrid carbides. The compressive strength was increased by 17% using 4% tungsten carbide, while flexural strength was increased by 39% at 4% tungsten carbide. The significant effect of carbides on flexural strength was also corroborated by ANOVA analysis. The improvement in flexural strength makes both carbides desirable for use in concrete pavement. Additionally, the permeability, the leading cause of durability issues, was reduced considerably by using tungsten carbide. It was concluded that both carbides provide promising results by enhancing the mechanical properties of concrete and are compatible with concrete to produce composites.

“…These standards make it possible to increase the dimensions of the slabs (driving down construction and maintenance costs, while providing better driving comfort due to a lower number of expansion joints) and to reduce their thickness (diminishing construction costs) by using different types of reinforcement and/or additives to the concrete mixes to improve their strength parameters [ 6 , 7 ]. Owing to, i.a., the results obtained in [ 8 , 9 , 10 ], the developed technology may provide an attractive alternative for slab reinforcement. The technology itself does not directly offer the effect of increasing the strength of the concrete layer (it may even decrease it), but makes it possible to reduce tensile stresses.…”

Thermal Diffusivity of Concrete Samples Assessment Using a Solar Simulator

The thermal properties of pavement layers made of concrete with varying bulk densities are a particularly interesting topic in the context of development road technologies. If a hybrid layer system is used as a starting point, with thin asphalt layers (from 1 cm to 4 cm) laid on top of a foam concrete layer, thermal properties begin to play a crucial role. The main research problem was to create a test method enabling the assessment of the influence of solar heating on the thermal parameters of the building material, especially cement concrete. For this reason, this paper is concerned specifically with the assessment of a new methodology for testing and calculating the value of the thermal diffusivity coefficient of samples made of concrete varying bulk densities. In this case, using the proprietary concept the authors built a solar simulator using a multi-source lighting system. The analysis of the results of laboratory tests and numerical analyses allowed the authors to observe that there is a strong correlation between the bulk density of samples heated and the thermal diffusivity parameter, which appears in the unidirectional heat transfer equation. The strength of this relationship has been expressed with the coefficient of determination and amounts to 99%. The calculated values of the coefficient of thermal diffusivity for samples made of foam concrete range from 0.16×10−6m2s to 0.52×10−6m2s and are lower (from 2.5 to 8 times) than the value determined for samples made of typical cement concrete.

“…Investigating how these methods are applicable to concrete pavements to mitigate or procrastinate these distresses getting worse by improving the flaws of concrete discussed above seems to be worthy and beneficial in many ways. Most of those studies maintain their conclusions as mixing various types of fibers and additions with desired dosages gives promising solutions in terms of flexural strength, compressive strength, tensile strength enhancements and, also fatigue and durability enhancements [3][4][5][6][7][9][10][11][12]. Also, few studies report the feasibility of using graphene-based nanomaterials as anticorrosive substances for steel reinforcement, which will address the reinforcement corrosion issues [34,[36][37][38].…”

“…In practice, plain concrete pavements are used mostly for foot paths and roads where very low traffic is accommodated. There are enough studies where addition of fibers, such as steel [3,4], synthetic [5][6][7][8], glass [9][10][11][12] and graphene-based nanomaterials [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], have been used in pavements to compromise the issue in plain concrete pavements, which can be termed as fiber-reinforced concrete pavements (FRCP). Different fibers are proven to increase the flexural strength, fatigue strength and other pavement-related concrete properties in different ways and different levels of performance.…”

“…Therefore, it is necessary to investigate how these fibers and additions act in these concrete pavements and improve pavement performance indices. Even though there are various fibers [3][4][5][6][7][9][10][11][12] in use, the present study aims at investigating the use of graphene and graphene oxide in the above context. To start with, first, types of distresses in concrete pavements (CRCP) are discussed and the anticipated mitigation approaches are identified.…”

Application of Graphene-Based Nanomaterials as a Reinforcement to Concrete Pavements

2022

View full text Add to dashboard Cite

Nanomaterials are considered to be one of the game-changing features in the modern world and nanotechnology is mostly reputed as the next-generation industrial revolution due to the extraordinary characteristics possessed by them at their very small scale. Graphene and graphene oxide are two main nanoscale materials that have seen a drastic increase in their use in cement-based composites due to exemptional enhancements in terms of strength and durability that can be imparted to compromise the inherent flaws of concrete and other cementitious composites. The main aim of this study was to investigate the effect of graphene and graphene oxide on improving the performance of cement-based composites and, particularly, of continuously reinforced concrete pavements (CRCP), which is one of the emerging trends in the transport sector due to various advantages they bring in over conventional flexible pavements and unreinforced concrete pavements. Fresh, hardened and durability properties of concrete with graphene-based nanomaterials were studied and the past experimental data were used to predict statistical interferences between different parameters attributed to concrete. According to the review, graphene-based nanomaterials seem to be promising to overcome the various CRCP distresses. Simultaneously, the possibilities and hinderances of using graphene and graphene oxide in cement-based composites as a reinforcement are discussed. Finally, the potential of using graphene in continuously reinforced concrete pavements is explored.
