Insufficient utilization of industrial solid waste and the high carbon emissions caused by use cement in engineering construction are two challenges faced China. This study aimed to develop a multi-source cementitious material (MSWC) for fluidized solidified soil (FSS) backfill projects. First, response surface models unconfined compressive strength (UCS) MSWC-FSS were established, optimal mixing ratio MSWC was determined. Subsequently, laboratory tests conducted compare differences flow...
Having the advantages of high permeability and strength, pervious concrete is suitable for improving ground-bearing capacity. In Yellow River Delta, a pile (PCP) composite foundation has been constructed to reduce settlement an expressway embankment. To study working mechanism PCPs, numerical model was based on finite-difference method Biot's consolidation theory, which validated by data from in situ tests. The excess pore-water pressure, pile–soil stress ratio, lateral displacement, PCP...
A novel hyperbranched charring agent containing s-triazine, diphenylmethane and urea groups (HBPU) was synthesized from melamine 4,4′-diphenylmethane diisocyanate, which is hydrophobic thermally stable at high temperature (residual weight being 40% 800 °C). HBPU ammonium polyphosphate (APP) are synergistic for the improvement of flame retardancy smoke suppression polypropylene (PP). With addition 30% APP (2:1 or 3:1), PP composites could reach V-0 rating UL-94 test, their peak heat release...
Due to their high permeability and strength, pervious concrete piles (PCPs) can improve ground bearing capacity. However, clogging of in practice is a potential disadvantage. To investigate the mechanism PCPs due sand piping, series laboratory simulation tests conducted on developed hydraulic conductivity test system. This testing demonstrates effects porosity, grading fine movable particles, mix ratio skeleton particles relative density soil, distance between PCP clogging. The experimental...
The deterioration of soil-cement in a saline environment leads to reduction strength and an increase permeability. Effective methods determining the deteriorated layer permeability coefficient are currently lacking. A laboratory test method for measuring was proposed using modified testing apparatus. According method, could be obtained after specimen acuring room equivalent depth environment. Using marine dredger fill from Jiaozhou Bay as case study, coefficients soil-cements with different...
In geotechnical engineering, geosynthetics are widely used as a reinforcement material for its numerous advantages. Moreover, strain monitoring is increasingly crucial to ensure the safety of reinforced structures. Therefore, new sensor-enabled geosynthetic named geobelts (SEGB) was developed and manufactured. The SEGB has function while achieving self-monitoring strain. Its essence kind conductive polymer, which made from super carbon black (CB) high-density polyethylene (HDPE). To study...
Since the concept of pervious concrete pile (PCP) was put forward as a technology ground improvement, some numerical simulations and small-scale tests have been performed to study properties PCP composite foundation. However, this has not implemented in field. In work, PCPs were installed by employing method vibrating-sinking tube series are evaluate The on cores indicate is suitable for installation PCP. Compared with gravel column soil-cement mixed pile, significantly increase time rate...
The permeability coefficient is the foundation of evaluating clogging and maintenance. In this study, 384 field tests were carried out on 9 positions using single-ring double-ring permeameters with different diameters. Both falling head constant methods evaluated. At same time, core samples drilled from test positions, their coefficients measured in laboratory. results show that there a good correlation between method method, both them can be used to measure in-situ pervious pavement....
In view to many problems on the traditional way of Just-In-Time (JIT) production not suitable for varieties small batch production, this paper proposed a new strategy solving these based improved kanban techniques, namely, visualization techniques. By comparing with kanban, performance has been proved be efficient and more applicable variety production.
Due to the intense capillarity action on low-liquid limit silt subgrade, subgrade is often overwet. The technology of sleeve valve pipe grouting an effective reinforcement method overwet subgrade. However, there are limited studies mechanism and its effects. In this study, four large-scale models were set up. Distributions moisture content physical mechanical indexes soil in different subgrades analysed. Integral stiffness deformation characteristics studied by cyclic step loading tests....
Pervious concrete pavements have good drainage and noise reduction capabilities, also the ecological function of regulating surface temperature humidity; they been widely used in many countries. However, capacity will be greatly decreased once pores become clogged permeable pavements. This study tries to reveal mechanism sediment clogging pervious pavement under runoff provide bases for optimizing design. A series laboratory tests conducted demonstrate effects slope, size, inflow rate,...
Cement-sodium silicate grout (CSG) is now widely adopted in water plugging engineering to prevent inrush disasters, and the gelation consolidation characteristics of CSG environment significantly affect grouting effect. To obtain an in-depth understanding performance water, CSGs with different water-cement ratios volume were tested, properties, deposition diffusion process within examined. The compressive strength microstructure formed air also analyzed comparatively. test results indicate...
