“…X-ray diffraction analysis was conducted on the cured self-compacting concrete (SCC) samples after 28 days of curing to gain insights into the crystalline composition of the material [36,37]. The XRD analysis aimed to identify the mineral phases present in the SCC specimens containing artificial aggregate (AF) and fly ash (FA) as partial replacements for CA and cement, respectively.…”

“…The utilization of admixtures, specifically high-range water-reducing (HRWR) and viscositymodifying admixtures, meets the stipulated criteria as per code. The formulation of selfconsolidating concrete (SCC) necessitates careful consideration to mitigate issues such as segregation, excessive bleed water, and the sedimentation of the coarse particles [27,36,37]. The resistance of SCC to frost and frost-thawing compounds can be enhanced through the incorporation of air entrainment [38,39].…”

Artificial aggregate (AF), i.e., silico manganese (SiMn) slag aggregate, is a byproduct of ferromanganese and silico manganese alloy production. The utilization of industrial waste and industrial byproducts in construction has increased the aim of conserving natural resources to nurture a pollution-free environment. The current study examines the performance of the use of artificial aggregate (AF) and partial replacement of cement with fly ash (FA). The properties of fresh concrete, as well as the compressive and flexural strength and split tensile strength of concrete were evaluated. Seven mix proportions were prepared for M30-grade concrete. The first was a control mix (with 0% AF and FA), three other mixes contained varying amounts of AF (20%, 40%, and 60%) as a partial replacement of CA with AF. The average compressive strength of the control SCC was found to be 32.87 MPa (megapascals) at the age of 28 days, and after replacing 20% natural aggregate with artificial aggregate, the compressive strength increased by 8.27%, whereas for 40% and 60% replacement, it decreased by 4.46% and 12.55%, respectively. Further investigation was performed on the optimum value obtained by replacing 20% of CA with AF. At this percentage, cement was replaced by FA at (15%, 25%, and 35%) where at 15%, the average compressive strength increased by 7.41%, whereas for 25% and 35% replacement, it decreased by 7.47% and 17.19%, respectively. For SCAF20 and SCF15, all strengths were at maximum due to the increase in its density. The findings show that the development of advanced construction materials is environmentally sustainable.

In this research, the effects of ultimate strain rate and environmental temperature on the mechanical performance of the aramid fiber bundles were experimentally investigated. The scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to detect the tensile failure mechanism of the aramid fiber bundle. The results indicated that the tensile strength, failure strain, elastic modulus, and toughness of the aramid fiber bundle were sensitive to the strain rate, which was represented as the typical bilinear monotonic relationships. In contrast, the impact of environmental temperature on the four parameters of aramid fiber bundle was more complex. The ultimate strength, failure strain and toughness of aramid fiber bundle increased with the temperature changing from −60 to 30°C, but rapidly decreased from 30 to 90°C. Finally, the dispersion of the mechanical performance was quantitatively analyzed based on the scale and shape parameters obtained from Weibull model.Highlights Tensile tests for aramid fiber bundle under different strain rates and temperatures were conducted. Strain rate and temperature effects on tensile properties of fiber bundle were quantified. Tensile failure mechanism of fiber bundle was analyzed. Dispersion of the mechanical performance was quantitatively analyzed.
