“…Concrete specimens were cast using standard concrete mix proportions following IS 456 guidelines [20]. Rectangular concrete beams with dimensions of 300 × 300 × 820 mm were cast for both LRC 45 and RC 90 [33]. The lacing angle was set at 45 degrees for LRC 45, while RC 90 had conventional 90-degree stirrups [34].…”

This experimental research evaluates the structural performance of laced reinforced concrete beams in comparison to conventional reinforced concrete beams (RC-90) under reverse cyclic loading. Visual inspection revealed that LRC-45 exhibited superior crack resistance, even at high displacements, unlike RC-90, which displayed vertical cleavages and diagonal tension cracks. RC-90 demonstrated minimal ductility, initiating cracking at lower loads. Hysteresis response curves showed LRC-45 outperforming RC-90 in terms of cracking load and maximum load, with higher displacement capacity. The ductility factor of LRC-45 was 56.39% higher. Notably, LRC-45 exhibited a substantial 143.43% increase in cumulative energy dissipation, highlighting its superior energy-absorbing capacity. Additionally, stiffness analysis indicated significantly higher stiffness in LRC-45. The numerical analysis supported experimental findings, emphasizing the potential of laced reinforcement in enhancing structural resilience, energy dissipation, and stiffness. The novelty lies in the remarkable improvements offered by LRC-45, particularly its enhanced energy-absorbing capacity and stiffness, which are crucial for structures subjected to dynamic loads, such as seismic events.

“…In this experimental investigation, mixtures of 10 and 20mm Normal Weight Aggregates (NWA's) are employed [47]. ASTM C33 standards were used to conduct several tests (Table 1 summarises the results of these testing) [39]. Additionally, the ratio of coarse aggregates (1 -20 cm) employed to present investigation is one part to 4 parts [48].…”

<p>Concrete is an indispensable construction material renowned for its versatility and durability, yet its traditional components pose significant environmental challenges. The cement industry is a major emitter of CO2, while the extensive extraction of natural aggregates depletes finite resources. In response, researchers have explored alternative materials like Marble Waste Powder (MWP) as sustainable substitutes in concrete production. This study investigates the feasibility of incorporating MWP as partial replacements for cement and fine aggregate, examining substitution fractions of 25% and 35%. Through experimental analysis, the mechanical properties and cost implications of these modified concrete blends are evaluated. The research findings reveal that integrating MWP into concrete formulations enables the production of high-strength concrete at a reduced cost, offering a promising solution to enhance the sustainability of construction practices. By partially replacing conventional materials with MWP, the environmental impact associated with concrete production can be mitigated, contributing to efforts aimed at reducing carbon emissions and conserving natural resources. Additionally, the study underscores the importance of eco-friendly innovations in construction materials, emphasizing the need for sustainable alternatives to meet the growing demand for infrastructure development while minimizing environmental harm. Overall, this research highlights the novel use of MWP as a sustainable alternative in concrete production, showcasing its potential to address environmental concerns and promote more eco-conscious construction practices. Through the exploration of mechanical performance and economic feasibility, the study provides valuable insights for advancing sustainability in the construction industry and achieving long-term environmental stewardship.</p>

“…For a quick assessment of the mortar's resistance to cation ion penetration, this test measures the electrical conductance of the material. The test procedure involves measuring the amount of electrical current flowing through disc specimens measuring 83 mm in diameter and 50 mm in depth, as well as specimens measuring 60 mm in diameter and 120 mm in depth, during the course of four, six, and eight hours [30][31][32]. One specimen is submerged in a solution of calcium hydroxide, potassium hydroxide, sodium hydroxide, and nano-silica, while the other three are immersed in calcium hydroxide, potassium hydroxide, and sodium hydroxide.…”

This study investigated the effects of electrokinetic treatments on mortar specimens using a range of experimental techniques. Ionic migration tests revealed that increasing voltage and duration led to higher charge transfer, with Ca(OH) 2 electrolyte showing the highest cationic migration. X-ray fluorescence analysis indicated that Nano-Silica treatment resulted in the highest oxide content, transforming absorbed elements effectively. The chloride penetration test demonstrated that Ca(OH) 2 treatment exhibited the lowest charge passed, suggesting minimal chloride penetration, while NaOH and KOH treatments showed higher charge passed. Field Emission Scanning Electron Microscopy analysis provided visual evidence of structural changes and material depositions. Calcium Hydroxide treatment reduced porosity, Sodium Hydroxide, and Potassium Hydroxide treatments displayed distinct particle distributions, and Nano Silica treatment led to the formation of hair-like crystal structures. These findings help to understand the microstructure and composition of cement mortar specimens after various treatments. The nano-silica electrolyte appeared as a viable choice for electro-kinetic therapy, whereas Ca(OH) 2 treatment stated the potential to reduce chloride penetration in mortar specimens. The results offer insights into optimizing electrokinetic treatments for improved mortar performance.
