Waste glass (WG) is unsustainable due to its nonbiodegradable property. However, main ingredient silicon dioxide, which can be utilised as a supplementary cementitious material. Before reusing WG, the flexural strength (FS) and alkali–silica reaction (ASR) expansion of WG concrete are two essential properties that must investigated. This study produced mortar containing activated powder using mechanical, chemical, mechanical–chemical (combined) approaches. The results showed 30% combined...
Construction and demolition (C&D) waste has become a research hotspot due to the need for environmental sustainability strength enhancement of cementitious materials. However, wider applications C&D are limited, as its non-homogeneous surface nature limits workability. This evaluated feasible utilization aggregates in polypropylene-fiber-reinforced cement-stabilized soil (CSS) under sulfate-alkali activation. CSS specimens incorporated Portland cement 10%, 20%, 30% proportions. Also,...
The glass fiber-reinforced polymer (GFRP) rebar reinforced cemented soil is widely employed to solve the weak foundation problem led by sludge particularly. robustness of this structure highly dependent on interface bond strength between GFRP tendon and soils. However, its application obstructed owing deficient studies influence factors. Therefore, study investigates effects water content (Cw: 50%–90%), cement proportion (Cc: 6%–30%), curing period (Tc: 28–90 days) peak residual strengths...
Self-compacting concrete (SCC) mixtures requires a large amount of Portland cement and thus resulting in high CO2 emissions, expanding its application has been question to environment sustainability. Accordingly, environmental-friendly alternatives SCC are deemed necessary for the progress construction. In this investigation, treated jute fibers mineral powders were used replace mixtures. The effects powder contents, fiber treatment, types on workability mechanical properties investigated...
Geopolymer, as a new type of solid waste-based inorganic cementitious material, exhibits outstanding Behavior in terms physical and chemical performance, macro-mechanical properties long-lasting stability, features potential application development tendency the field repair reinforcement existing concrete structures. This paper investigates interfacial geopolymer mortar with OPC substrate under different slag, fly ash red mud mixing proportions, while cement was used control group for...
Cement stabilized soil (CSS) yields wide application as a routine cementitious material due to cost-effectiveness. However, the mechanical strength of CSS impedes development. This research assesses feasible combined enhancement unconfined compressive (UCS) and flexural (FS) construction demolition (C&D) waste, polypropylene fiber, sodium sulfate. Moreover, machine learning (ML) techniques including Back Propagation Neural Network (BPNN) Random Forest (FR) were applied estimate UCS FS based...
Sulfate attack is one of the non-negligible factors that induces deterioration in performance and life cycle soil stabilizers. In this paper, degradation mechanism durability slag–fly-ash-based geopolymer stabilized soft (hitherto referred to as SF-GSSS) under sodium sulfate (Na2SO4) magnesium (MgSO4) environment comparatively investigated, slag/fly ash ratios are set S10F0, S9F1, S8F2, S7F3. The SF-GSSS was fully immersed a 2.5% Na2SO4 solution MgSO4 solution, respectively, characterize...

The load-transfer mechanism of tensioned anchors is primarily concerned with in-service performance, which depends on the bond–slip behavior anchoring interface. Because interface conventionally modeled using epistemic experience specific researchers and/or back analysis in situ testing results, it challenging to develop a straightforward extensive applicability. A generalized modeling framework was implemented this work by incorporating versatile model that can be derived from experimental...
Anchoring force loss is critically concerned for the in-service performance of prestressed ground anchors. This time-dependent pretension exerted at anchor head caused primarily by stress relaxation, which integrally manifests rheological properties and geomaterial in embedded. A load-transfer modeling framework was established to derive anchoring response. The parameters were directly calibrated via element-scale pullout relaxation test using a specially developed setup. applicability...
Abstract The performance of soil nail systems relies primarily on soil-nail interaction, which is especially complex for nails embedded in clay materials. Soil-nail interaction difficult to predict these soils because the effect moisture-induced stress and swelling along interface between nail. As part this investigation, tests were conducted characterize shearing mechanisms using a novel element pullout device that involves comparatively short under varying degrees saturation. Additionally,...
