“…Additionally, Dia et al (2021) [20] found that the addition of 0.025, 0.05 and 0.075 resulted in increasing flexural strength of cement pastes at 28 days by 14, 15 and 21%, respectively. In terms of concrete specimens, Arslan et al (2022) [13] reported that the addition of small amount of GNPs (less than 0.35 wt%) increased flexural strength of concrete specimens. However, when the amount of GNPs was higher than 0.35 wt% they reported that flexural strength was adversely affected.…”

“…However, when the amount of GNPs was higher than 0.35 wt% they reported that flexural strength was adversely affected. Similar to compressive strength, the reduction of the flexural strength may be due to the agglomeration of GNPs which caused defect in the cement matrix of the concrete specimens [13,19].…”

Carbon Dioxide (𝐶𝑂 2 ) is the principal greenhouse gas that contributes to increasing the greenhouse effect, which has a significant adverse impact on the environment. There are large quantities of carbon dioxide emissions associated with cement production. Production of cement is estimated to be responsible for approximately 8% of global greenhouse gas emissions. Besides its environmental impact, concrete also exhibits low tensile and ductility, which can result in cracks. In recent years, carbon nanomaterials, such as Carbon Nanotubes (CNT), Carbon Nanofibers (CNFs), Graphene Nanoplatelets (GNPs), Graphene Oxide (GO), and Reduced Graphene Oxide (rGO), have gained increasing attention from the building industry and scientific community due to their exceptional mechanical and physical properties. In fact, the use of carbon nanomaterials is considered an environmentally friendly method of enhancing the mechanical properties of concrete. The purpose of this study is to investigate the effects of GNPs on the mechanical properties of concrete using the wet dispersion method. In addition to using ultrasonic treatment to prepare GNP dispersions, a superplasticizer is also used to facilitate the dispersion of GNPs in water. Concrete specimens were prepared with 0.25 wt% GNPs. Compressive, flexural and tensile strength of concrete at age of 7 days were assessed. As a result of adding GNPs, strength of concrete specimens was enhanced. Furthermore, when GNPs were incorporated into concrete specimens, compressive, flexural and tensile strength was increased by 19, 8.7 and 9.1 % respectively.

Graphene, with its excellent properties and unique structure, has been extensively studied in the context of modifiable cement-based materials. However, a systematic summary of the status of numerous experimental results and applications is lacking. Therefore, this paper reviews the graphene materials that improve the properties of cement-based materials, including workability, mechanical properties, and durability. The influence of graphene material properties, mass ratio, and curing time on the mechanical properties and durability of concrete is discussed. Furthermore, graphene’s applications in improving interfacial adhesion, enhancing electrical and thermal conductivity of concrete, absorbing heavy metal ions, and collecting building energy are introduced. Finally, the existing issues in current study are analyzed, and the future development trends are foreseen.

This study aims to evaluate the mechanical properties of carbon fiber-reinforced reactive powder concrete (CFRPC) after exposure to cryogenic temperature. The mechanical properties of plain RPC and CFRPC with carbon fiber volume contents of 0, 0.5%, 1.0%, and 1.5% were examined after exposure to 20 °C, −5 °C, −15 °C, and −25 °C for 72 h. The effect of fiber contents and exposure temperatures on the cubic and axial compressive strength, splitting tensile strength, elastic modulus, and peak strain were systematically reported and analyzed. The results showed adding carbon fiber to RPC could significantly enhance the strength and slightly improve ductility performance. Additionally, CFRPC with 1.0% fiber content showed the best mechanical properties. The maximum increases in cubic and axial compressive strength and tensile strength were 26.0%, 25.7%, and 21.8%, the elastic modulus was 13.2%, and the peak strain was 13.0% over the plain RPC. Additionally, all mechanical properties continued to degrade with decreasing temperature. After exposure to −25 °C, the cubic, axial compressive strength, and tensile strength of CFRPC degraded to 82.2–84.9%, 80.7–87.5%, and 72.7–73.7% of the normal temperature strength, respectively. In addition, the linear relationship equation between the discount factor of each mechanical property and the temperature was established. Finally, the equation for the stress–strain ascending curve of CFRPC described by a quadratic polynomial was proposed, which fitted well with the experimental results.
