Efficacy of geopolymerization for integrated bagasse ash and quarry dust in comparison to fly ash as an admixture: A comparative study

Journal of Engineering Research, Journal Year: 2023, Volume and Issue: unknown

Published: Aug. 1, 2023

This study compares the efficacy of geopolymerized bagasse ash (GB) and quarry dust (GQ) with traditional flay ash-based geopolymer considering strength properties a subgrade. Geopolymerized composited binary admixture (GBA) was constituted by incorporating optimum percentages GQ GB, on basis maximum reduction 70% 52% in plasticity index value respectively. Then samples for tests such as unconfined compression California bearing ratio were remolded using standard modified compaction parameters. Also, mineralogical microstructural analyses conducted based SEM EDS. The influence curing percentage geopolymers also investigated properties. performance GBA is equivalent to fly-ash-based (GF) like qu CBR ensuring more than 200% increase at 20% 15% content However, these contents, ductility GBA-treated 107% higher GF making this suitable under dynamic load. Formation gel ((N, C)-A-S-H) confirmed elemental but microstructure treated sample porous sample, which provides some advantage particles reorientation load before failure. proposed multi-waste has significant implications waste management, its implementation construction two-lane subgrade covering distance 1 kilometer may enable repurposing 1313 tons assorted solid waste.

Experimental Study on Post-Grouting Pile Vertical Bearing Performance Considering Different Grouting Methods and Parameters in Cohesive Soil

Applied Sciences, Journal Year: 2023, Volume and Issue: 13(22), P. 12175 - 12175

Published: Nov. 9, 2023

The selection of grouting methods and parameters significantly affects the improvement in pile-bearing capacity cast-in-place bored piles. This study proposes a comprehensive set test for constructing model piles, performing at pile tip side. A series single-pile static load tests were conducted using these methods. results reveal that pile-side is more effective controlling settlement compared to grouting. Furthermore, tip-side-combined exhibits superior reinforcement effects other two After grouting, grout bubble formed outlet, consisting compact diffusion zone internally split externally. Additionally, vertical occurs along body, establishing lateral friction resistance enhancement region. Within this region, shows negative correlation with distance from outlet. emphasize significance volume its impact on bearing capacity, control, resistance, size grouted while influence variation pressure small range characteristics not apparent.

Effect of Fine-Grained Particles and Sensitivity Analysis of Physical Indexes on Residual Strength of Granite Residual Soils

Coatings, Journal Year: 2024, Volume and Issue: 14(1), P. 105 - 105

Published: Jan. 12, 2024

Recently, stability analyses of structures built granite residual soils, for example, earth dams or other urban structures, particularly when under vibration, are being recognized as much more important than previously imagined. In such analyses, it is emphasized that the strength should be utilized considering seismic effect. Therefore, soils must evaluated accurately in order to reduce damage on them. This paper presented a laboratory study designed examine effect fine-grained particles (FGPs; particle size ≤ 0.075 mm) by multistage procedure Bromhead ring shear test and evaluate physical indexes forecasting using soil samples composed fifteen different percentages FGPs artificially adjusted from reservoir embankment sample. The results showed decreased along with increase frictional angle was rarely dependent ratio over 90%. Even state, small amplitude fluctuation stress still existed affected coarse-grained (CGPs; ≥ mm), quartz soils. It also found smaller FGP fraction greater. addition, same normal stress, peak an FGPs. Then, they remained almost ratios were equal 85% 90%, respectively, post-peak attenuation tended initially then same. Moreover, based sensitivity analysis, influence ranked
