“…Dimitar et al [13] reported that nanoengineering concrete with graphene reinforcement results in cement composites possessing ultrahigh strength. Similarly, Reddy et al [14] observed a substantial increase in compressive strength with the addition of 0.05% to 0.15% graphene oxide to concrete. However, they noted a decrease in strength at a 0.20% admixture level, likely attributable to graphene oxide agglomeration.…”

In order to overcome the limitations of traditional pervious concrete, which is difficult to balance in terms of both mechanical properties and permeability, this study proposed a novel and effective approach to improve the performances of pervious concrete (PC) based on hexagonal boron nitride (h-BN) and basalt fibers (BF). The mechanical properties and permeability tests of PC with single-doped or double-doped h-BN and BF were conducted first. Then the influence laws of h-BN and BF content on the compressive strength, flexural strength, porosity, and permeability coefficient for PC were revealed. Finally, the micro-mechanism effects of h-BN and BF on the performances of PC were explored by using a scanning electron microscope and an energy dispersive spectrometer. The results showed that the compressive strength of PC was increased with the increase in the h-BN content, and the flexural strength, porosity, and permeability coefficient increased first and then decreased. Meanwhile, with the increase in the BF content, the compressive strength and flexural strength of PC increased first and then decreased. Moreover, the compressive strength, flexural strength, porosity, and permeability coefficient of the proposed pervious concrete were 22.8 MPa, 5.17 MPa, 18.5%, and 5.09 mm/s, respectively, which were increases of 21.9%, 19.7%, 60.9%, and 42.2%, respectively, compared with ordinary permeable concrete when the optimal admixture combination was 15% fly ash, 0.08% h-BN, and 2.25% BF. This study can avoid the limitations of traditional pervious concrete and provide an efficient alternative way for improving the mechanical and permeability properties of pervious concrete.

“…As per this study optimum dosage was 0.025% for most of the parameters determined [3]. In a similar research PVRK Reddy et al attempted to determine the dynamic properties of cement composites containing GO, focusing on determination of natural frequency, damping ratio and mode shapes for concrete structural elements containing GO [4]. Moreover, in a similar research Byoung Hooi Cho et al attempted to study the flexural fatigue life of concretes containing various combinations of steel fibers and GO nano flakes for application in rigid pavements [5].…”

Effective utilization of industrial byproducts as mineral admixtures and filler materials in cement concrete has been a practice to develop sustainable construction materials. The use of mineral admixtures like fly ash, silica fume, ground granulated blast furnace slag etc. as a partial replacement of cements have proved to improve the performance characteristics of concrete through reduced porosity and improved mechanical characteristics through pozzolanic effect and filler effect. Moreover, extensive research in the recent period has been mainly focused to study the effect of nano-additions in concrete. The present work was focused to assess the performance of ternary blended high performance self-compacting concretes with varied quantities of graphene oxide additions. Control concrete of M60 grade was designed in correspondence to IS-10262:2019 containing fly ash, and three other concretes mixes were formulated with 0.03%, 0.06% and 0.09% addition of Graphene Oxide (By weight of total cementitious material). The specimens were cast and tested at different ages to determine rheological, mechanical and durability characteristics by evaluating slump flow, Compressive Strength, Split Tensile Strength, Absorption- Desorption characteristics, Rapid Chloride Penetration Test values and resistance to accelerated corrosion cracking. Moreover, the specimens were assessed for corrosion resistance by conducting a cyclic wet – dry test, where parameters like UPV & depth of chloride penetration in concrete were measured. Results depict the fact that addition of Graphene Oxide improves the durability characteristics to a great extent. The optimum results for most of parameters were obtained at 0.06% of Graphene Oxide addition in comparison to remaining mix proportions.

“…Due to the influence of curing time, the oxygen content, diameter, thickness, and lifting efficiency of different tests are also different. However, it can be seen from the references [ 51 , 52 ] that the increase of concrete compressive strength gradually decreases with the increase in curing time. This is because the main product of the hydration reaction in concrete is calcium silicate hydrate gel, which is the primary source of early strength in concrete.…”

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.
