The purpose of this study is to investigate the individual and admixed effects sawdust ash (SDA) high calcium fly (HCFA) on geotechnical characteristics expansive soil (ES). effectiveness these pozzolanic materials was examined, particularly tests their physical mechanical potential enhancing mixing ratio for ES stabilization adopted as 70:30 by fixed dry weight, based HCFA/SDA mixture plasticity strength. Cement added optimal in varying amounts (1%, 0.5%) increase HCFA reactivity. results...
To investigate the soil structure and mechanical behavior of an unsaturated expansive clay soil, triaxial mercury intrusion tests have been performed are presented in this paper. Also optical test system was developed for studying internal evolution during shear-loading tests. The research results show a linear relationship between cohesion intercept degree saturation data. For tested pore-size distribution curves were found to be bimodal. measurement from confirm that micropores Guangxi...
Incorporating foam into slurry can improve its wall-supporting performance. However, the wall formation mechanism of under different conditions remains unclear. In this study, numerical simulations were conducted to investigate influence soil properties, composition, and pressure gradient on infiltration process effectiveness slurry, which was validated through laboratory experiments. The results indicate that in be divided three stages—infiltration, clogging, membrane formation. time...
Summary The study investigated the feasibility of replacing steel bars by bamboo in concrete members as alternative materials rural and peri‐urban areas. present also effects bonds between on strength reinforced with treated untreated bamboo. further examined effect split whole when used reinforcements compare bars. Laboratory tests such pull out test, flexural water absorption tensile mechanical crushing test were done for this purpose. Nonlinear finite element model using ABAQUS was to...
The soil–water characteristic curve (SWCC) and pore-size distribution (PSD) are fundamental characteristics of soils that determine many physical mechanical properties. Recent studies demonstrate both SWCC PSD sometimes exhibit a bimodal feature. In this paper, with SWCCs mainly divided into three categories: gap-graded soils, compacted clayey natural dual-porosity structural from the perspective microporosity structure. Based on Fredlund Xing unimodal equation, equation is presented. <math...
Abstract In excavated earth structures (e.g., deep excavation, cut slope, and underground construction etc.) unloading is the most predominant factor that affects behavior of soil mass. However in engineering practice, influence has not been really considered. For example, shear strength characteristics are often investigated from conventional triaxial test, consequently it leads to some doubts when applying properties under loading condition analyze stability displacement problem cases....
The yielding and the peak strength of an aged compacted clay were studied by conducting a series suction-controlled triaxial tests. test results interpreted using framework intrinsic properties reconstituted soil. envelopes undisturbed samples lie above those samples. suction provides additional attractive forces to stabilize soil structure, which result in augmentation yield stress envelope. shear is normalized equivalent preconsolidation pressure (pe′) Hvorslev surfaces are identified from...
This study investigated the unconfined compressive strength change law of cement modified slurries (CMS) under different curing ages. We conducted tests using slurry and as raw materials. The contents were 5%, 10%, 15%, 20%, 25%. ages 7, 14, 28, 56, 90, 120, 150, 180 d. A time effect model CMS was established based on measured UCS strength‐curing age strength‐cement content curves. test results proved that increased significantly with an increase in age, after 90 days, gradually to a fixed...
