Optimization of steel anchor pile configurations for enhanced pullout resistance in expansive soil foundations.

This study aims to predict the pullout behavior of steel anchor piles in saturated expansive soil using finite element method-based PLAXIS 3D CONNECT Edition V22 software. It inspects the effects of varying pile parameters and spacings for a displacement of 10% of the pile diameter. The study evaluates the performance of single and group anchor piles by comparing square configurations (2 × 2, 3 × 3, and 4 × 4) at varying centre-to-centre (c/c) spacings of 2.

Sustainable subgrade improvement with calcium carbide residue and rice husk ash.

Expansive soils, particularly black cotton soil (BCS), present significant engineering challenges due to their high swelling potential and shrinkage behavior, leading to structural instability. This study evaluates the stabilization potential of calcium carbide residue (CCR) and rice husk ash (RHA) by assessing their combined effects on the geotechnical properties of BCS. Laboratory tests, including differential free swell (DFS), compaction, unconfined compressive strength (UCS), and California bearing ratio (CBR), were conducted to determine the optimal mix proportions.

LC-MS/MS characterization of pirtobrutinib impurities and product degradation: stability studies.

This study examined the fragmentation, degradation pathways and DPs of pirtobrutinib, which have not been previously reported in the literature. The main goal of the current work is to develop, validate, and characterize forced degradation products using LC-MS/MS. An isocratic HPLC methodology was developed for the quantitative measurement of pirtobrutinib at a of 219 nm.

Investigating the Flexural Behavior of a Two-Span High-Performance Concrete Beam Using Experimentally Derived Stress Block Parameters.

High-performance concrete (HPC) is increasingly used in construction due to its superior strength and durability. However, current stress block parameters used for designing normal-strength concrete cannot be safely applied to HPC. To address this issue, new stress block parameters have been proposed through experimental works, which are used for designing HPC members.

Mechanical Properties of High-Strength Self-Compacting Concrete.

In this research work, the mechanical properties of high-strength self-compacting concrete (HSSCC) were studied. Three mixes were selected, having compressive strengths of more than 70, 80, and 90 MPa, respectively. For these three mixes, the stress-strain characteristics were studied by casting cylinders.

Al2014-Alumina Aerospace Composites: Particle Size Impacts on Microstructure, Mechanical, Fractography, and Wear Characteristics.

An Al2014-alumina (AlO) composite's characteristics are significantly influenced by the reinforcement particle size variation. Therefore, this study examines the microstructure, mechanical, fractography, and wear performance of an Al2014-AlO composite made using a unique two-stage stir casting method and various alumina weight fractions (9, 12, and 15 wt %). Three categories of alumina particle size are used, i.

Development of Eco-Friendly Concrete Mix Using Recycled Aggregates: Structural Performance and Pore Feature Study Using Image Analysis.

The shortage of natural aggregates has compelled the developers to devote their efforts to finding alternative aggregates. On the other hand, demolition waste from old constructions creates huge land acquisition problems and environmental pollution. Both these problems can be solved by recycling waste materials.

Current solid waste management strategies and energy recovery in developing countries - State of art review.

Solid waste generation has rapidly increased due to the worldwide population, urbanization, and industrialization. Solid waste management (SWM) is a significant challenge for a society that arises local issues with global consequences. Thus, solid waste management strategies to recycle waste products are promising practices that positively impact sustainable goals.
