“…The selfcompacting concrete that produced the best compressive strength and satisfactory fresh concrete results used up to 20% marble waste as a partial replacement for fine aggregate [6]. The study examined how the amount of cement and marble paste in self-compacting concrete affected its rheological characteristics and strength [7]. It was found that the SCC mix designs with various cement and marble paste volumes show good correlations between their fresh and hardened characteristics, and that the substantial addition of marble powder produces a mix with microstructures that affect both the rheological properties and the compressive strength of self-compacting concrete [8].…”

This study looked into the possibility of substituting marble dust for some of the fine aggregates used in concrete production. The purpose was to determine if such a substitute may improve concrete’s properties while also minimizing the negative consequences of mining and processing natural sand and assisting in the attainment of sustainability goals. Experimental testing was done on a variety of concrete mixtures that contained various amounts of sand and marble dust. Compressive strength, flexural strength, and workability were evaluated for a control mix consisting entirely of unrefined sand. The results showed that there was little difference in concrete’s compressive or flexural strength when up to 30% marble dust was used in place of sand. The workability and strength, on the other hand, decreased as marble dust concentrations rose. contains marble dust.

“…Further, the fatigue life of polypropylene-fiber-reinforced concrete (PFRC) is significantly improved compared with that of plain concrete [46,47]. The use of polypropylene fibers in SCC significantly affects the resulting concrete's mechanical properties and crack propagation [48][49][50]. However, traditionally available polypropylene fibers are tiny, have smooth surfaces, and are very soft.…”

Concrete is one of the most commonly used construction materials; however, its durability plays a pivotal role in areas where the concrete is exposed to severe environmental conditions, which initiate cracks inside and disintegrate it. Randomly distributed short fibers arrest the initiation and propagation of micro-cracks in the concrete and maintain its integrity. Traditional polypropylene fibers are thin and encounter the problem of balling effects during concrete mixing, leading to uneven fiber distribution. Thus, a new polypropylene fiber is developed by gluing thin ones together, forming macro-polypropylene fibers. Thus, different amounts of fibers, 0–1.5% v/f with an increment of 0.5% v/f, are used in different grades of concrete to study their impact on durability properties, including resistance to freezing and thawing cycles, sulfate, and acid attacks. A total of 432 cube samples were tested at 28, 56, and 92 days. The results reveal that the maximum durability, in terms of compressive strength loss, is noted with a fiber content of 1% with improved resistance of 72%, 54%, and 24% against freeze–thaw cycles, sulfate attack, and hydrochloric acid attack, respectively, at 92 days. Thus, the resulting fiber-reinforced concrete may be effective in areas where these extreme exposure conditions are expected.

“…The unique composition and mixing proportions of SCC demand a thorough investigation of its mechanical properties, which differ significantly from those of regular vibrating concrete [1]. Since it has the potential to reduce building costs, improve the workability, and enhance the durability, SCC has gained popularity in various construction projects [2]. However, the full appreciation of SCC's potential is hindered by the lack of comprehensive research on its mechanical characteristics.…”

The performance of self-compacting concrete (SCC) is gaining popularity in construction due to its exceptional strength and durability. However, the properties of combined steel and concrete at elevated temperatures lack experimental data from previous research. This study aimed to investigate the behavior of the SCC core with a steel tube at ambient and elevated temperatures varying from 100 °C to 800 °C with 100 °C intervals for each test specimen. Tests were conducted on circular steel tubes filled with SCC for different grades (M25, M30, and M40) under compression at elevated temperatures. Experimental observations revealed that the stress–strain curve increased with increasing the cross-sectional area and grade of concrete. However, increasing the temperature and length-to-diameter ratio reduced the stress–strain curve. At elevated temperatures, confined SCC experienced a smaller decrease in the overall modulus of elasticity when compared to unconfined concrete. Within the compressive elastic region (from 30 °C to 400 °C), there was a significant relationship between lateral strain and longitudinal strain, which was followed by a sudden increase beyond 400 °C. Equations for various design parameters were proposed based on the peak load and confinement factor of confined SCC-filled steel tubes (SCCFSTs) via multiple regression. Moreover, this study developed load–axial shortening curves, identifying significant properties such as the yield strength of confined SCCFSTs, including the load-carrying capacity. The predicted numerical analysis results were well aligned with the experimental results, and the findings contributed valuable insights for designing resilient and durable combined SCC and steel tube infrastructures.
