The flexural behavior of geogrid-reinforced foamed lightweight soil (GRFL soil) is investigated in this study using unconfined compressive and four-point bending tests. effects wet density reinforcement layers on performance are analyzed load–displacement curves, damage patterns, load characteristics, strength, strength. A variance demonstrates that increasing the significantly increases Bond stress mechanisms enable geogrid integration, efficiently reroute stresses internally, greatly...
Alkali-activated copper tailings based-pastes (AACTP) were synthesized using 90 wt% and 10 coal fly ash as the precursors, water glass with sodium hydroxide alkaline activator. The effects of formation pressure, liquid/solid mass ratio to precursor materials, partial substitution CaO for NaOH activator investigated. highest compressive strength 40.9 MPa was obtained a pressure 20 MPa, 0.15, 20% characterization Mercury Intrusion Porosimeter (MIP) indicated that affected pore structure, well...
To investigate the dynamic response of silt-based foamed concrete as filler in subgrade, this paper conducted staged cyclic loading experiments to examine its properties. Influence factors such wet density and silt content were also addressed experiments. The results tests indicated that hysteretic curves presented obvious elastoplastic characteristics, stress–cumulative strain have a strain-hardening phenomenon. Dynamic strength increased mean level 65% when by an average 100 kg/m3 at range...
The effects of steel slag (SS) and fly ash (FA) on hydration heat, fluidity, setting time rheological properties alkali-activated (AAS) pastes with different silicate modulus (Ms) values were comparatively investigated. results show that the incorporation SS shortens induction period, increases cumulative improves initial fluidity decreases at low Ms, but opposite trend is found high Ms. FA significantly retards reaction, reduces prolongs time. addition or yield stress plastic viscosity AAS...
Vehicle-pedestrian conflicts have been the major concern for traffic safety. Surrogate safety measures are widely applied pedestrian evaluation. However, how to quickly identify vehicle-pedestrian surrogate at individual site is challenging due difficulty of obtaining high-resolution trajectories road users. This paper presented an effective method generate from roadside deployed Light Detection and Ranging (LiDAR) sensor. The can then be identified simply using speed-distance profile (SDP)...
The silt-based foamed concrete, in which the cement is partially replaced with silt, has become a novel material road construction projects. However, at present time, only few studies have been completed attention was paid shear strength of aforementioned type subgrade applications. Therefore, order to address those issues, this research investigation conducted triaxial tests. During experimental testing processes, mechanical behaviors concrete specimens were examined. Such influencing...
Fiber-reinforced silica aerogel blankets (FRABs) are an important high-temperature thermal insulation material for industry applications that have emerged in recent years. In order to better understand the performance evolution of FRABs at high temperatures, effect heat treatment different temperatures on as well their base material, hydrophobic powder and glass wool, was investigated. The property showed two stages with increase temperatures. skeleton structure remained unchanged, but...
Slag and fly ash (FA) are mostly used as precursors for the production of alkali-activated materials (AAMs). FA is waste discharged by power plants, while slag steel (SS) both belong to iron industry. The effects SS on strength, microstructure, volume stability (AAS) with different water glass modulus (Ms) values were comparatively investigated. results show that adding or decreases compressive strength AAS mortar, reduction effect more obvious at high Ms. reduce non-evaporable content (Wn)...
Balancing detection performance and computational efficiency is critical for sustainable pavement disease in energy-constrained scenarios. However, existing visual methods often struggle to adapt structural transformations capture features of diseases complex environments, while their demands can be resource-intensive. To address these challenges, this paper proposes a structure perception feature attention network (SPFAN). The includes module that employs the updated deformable convolution...
To address the challenge of balancing static and dynamic strength in engineering application foam concrete, this study proposes a strategy to improve mechanical properties concrete by synergistically adding rubber particles polypropylene fibers, systematically analyzes effects content, particle size, fiber content on material’s compressive strength, flexural impact toughness. The results show that enhances through high elastic deformation, with maximum increase up 200%. However, due...
