“…As loading progressed, the undersurface of the slabs gradually developed cracks, signifying the transition to the elastic-plastic stage. During this juncture, the cracking load of the RCM60 laminated base slab was approximately 20.1% lower than that of RAC60, while RCM130 exhibited a reduction of about 6.1% compared to RAC130; some phenomena in the experiment were similar to those in the existing research [39][40][41][42]. The incorporation of manufactured sand admixture accelerated the initiation of cracking, as indicated by this divergence.…”

“…By comparing RCM with RAC, this experiment assesses the fundamental performance of both concretes. The deflection changes and crack propagation forms in unidirectional laminated slabs under loads were studied, and the characteristic loads during the construction and use stages of unidirectional laminated slabs were determined and compared with other similar studies [39][40][41][42]. Additionally, load-deflection curves are established and compared with similar experiments [43][44][45].…”

To align with the trend of the development of prefabricated buildings, this study aimed to produce unidirectional laminated slabs by using recycled concrete with manufactured sand (RCM). Additionally, performance evaluation and loading simulation analyses were conducted on these unidirectional laminated slabs. The experimental results indicate that the mechanical characteristics of RCM closely approximate those of recycled aggregate concrete (RAC), and they are all higher than the design value. Under ultimate loading conditions, the mid-span deflection of laminated slabs fabricated with RCM surpasses its RAC counterpart by 5.9%, indicating a pronounced proximity in flexural performance between RCM and RAC laminated slabs. Concurrently, ABAQUS finite element software was used to compare and simulate the performance of the unidirectional laminated slabs. The difference between the deflection generated by the actual applied ultimate load and the deflection generated by the simulated ultimate load is about 7.1%, and the simulation results are very close to the experimental results. Based on the experimental results, the practical application of RCM unidirectional laminated slabs has high value in the field of construction engineering.

“…The results of their investigation suggest that the incorporation of hybrid steel fibers can significantly bolster the tensile performance of the concrete, offering a promising avenue for improving the structural integrity and durability of SCC in applications where tensile resistance is critical. Fayed et al [23,24] conducted an experimental study on the bearing strength of recycled aggregate concrete reinforced with steel fibers (volume fractions are 0.5%, 1.5% and 2%) and the performance of steel fibers with 1%, 2% and 3% reinforced-concrete columns. Kalkan et al [25] studied the shear capacity of CNC scrap steel fibers and showed that the advantages of using scrap lathe waste emerge from several perspectives, including the type and quantity of the steel fibers and the range of reinforcement.…”

This study assesses the influence of extra-short extra-fine steel fibers on the performance of self-compacting concrete (SCC) modified with fly ash. Replacing standard steel fibers with volume fractions ranging from 0%, 1.5%, 3%, 5% and 6%, the study optimizes the mix design for enhanced workability and mechanical properties. The findings reveal that, although the addition of steel fibers had a negative effect on the flowability, the cohesion is significantly improved, providing a basis for a significant improvement in the mechanical properties. The optimal fiber content is identified at 5%, achieving the highest compressive strength of 71.7 MPa, split tensile strength of 8.2 MPa, and flexural strength of 12.8 MPa at 28 d. However, further increases in fiber content beyond 5% lead to a deceleration in compressive and splitting tensile strength improvement and a 27.5% drop in flexural strength at 28 d. The study also emphasizes the good dispersion within the concrete, which helps to enhance its ductility and crack resistance, to some extent.
