“…The findings of this research also put forward the remarkable contribution of borophene nanosheets to enhance the mechanical performance of cementitious composites. 51 An in-depth review of these limited studies revealed the lack of experimental studies of the cementitious composites incorporating borophene nanosheets to put forward the effects on the mechanical performance. Therefore, this gap has spurred the current experimental study investigating the use of borophene nanosheets in cement-based composites for the first time.…”

“…There are very few studies about the use of borophene in cementitious composites with different focuses but especially studies about the effect of borophene sheets on the mechanical properties of cementitious composites are still very limited. [50][51][52] In one of these few studies, it is reported that with the incorporation of 1.0 wt% of hexagonal boron nitride nanoflakes in cementitious composites, an 89 and 85% increase of compressive strength and toughness was observed compared to pure cement. 50 In another study conducting molecular dynamic simulations, by the use of borophene and graphene-filled calcium silicate in cementitious composites, the structural stability, resistance to compression, and high temperature were significantly improved.…”

This study is the first investigation focused on the preparation of novel synthesized borophene nanosheets and their use in cementitious composites. The two-dimensional β borophene was prepared by a facile and low-cost sonication process including ultrasonic cavitations. To understand the effect of the novel synthesized borophene nanosheets, varying ratios of 0, 0.5, 1, 2, 3, and 5 wt% of cement were incorporated in cement composites and improvements on the mechanical strength, workability, and toughness were identified. Also, for the microstructure evaluation, several advanced characterization techniques including SEM, EDS, XRD, and TGA were presented and the relationship between the microstructure and mechanical properties of cementitious composites modified with borophene nanosheets was discussed. As a result of this study, with the incorporation of the borophene nanosheets, clear improvements were achieved for the 28 day compressive and flexural strengths of the specimens within a range of 5–19% and 4–13%, respectively. The findings also indicated that borophene nanosheets contributed to the formation of a denser microstructure of the corresponding cement composites. Thus, within this study, the utility of as-prepared borophene nanosheets in cementitious composites is proved and proposed as a two-dimensional potential nanomaterial candidate to be used in cementitious composites.

With cement, bentonite, water glass, J85 accelerator, retarder and water as raw materials, a new composite grouting material used to seal groundwater inflow and reinforce wall rock in deep fractured rock mass was developed in this paper. Based on the reaction mechanism of raw material, the pumpable time, stone rate, initial setting time, plastic strength and unconfined compressive strength of multi-group proportion grouts were tested by orthogonal experiment. Then, the optimum proportion of composite grouting material was selected and applied to the grouting engineering for sealing groundwater inflow and reinforcing wall rock in mine shaft lining. The results show the mixing proportion of the maximum pumpable time, maximum stone rate and minimum initial setting time of grout are AK4BK1CK4DK2, AK3BK1CK1DK4 and AK3BK3CK4DK1, respectively. The mixing proportion of the maximum plastic strength and unconfined compressive strength of grouts concretion bodies are AK1BK1CK1DK3 and AK1BK1CK1DK1, respectively. Balanced the above 5 indicators overall and determined the optimum proportion of grouts: bentonite-cement ratio of 1.0, water-solid ratio of 3.5, accelerator content of 2.9% and retarder content of 1.45%. This new composite grouting material had good effect on the grouting engineering for sealing groundwater inflow and reinforcing wall rock in deep fractured rock mass.
