By analyzing its stress-strain relationship and combining low field nuclear magnetic resonance and scanning electron microscopy techniques, the microstructure and porosity changes of recycled plastic concrete were studied, and creep tests were conducted. The research results indicate that the stress-strain behavior of recycled plastic concrete in the elastic stage is similar to that of ordinary concrete, but in the yield and decay stages, its stress is higher and the decay rate is faster. The porosity of recycled plastic concrete and ordinary concrete are 5.48 % and 6.12 %, respectively, with the proportion of small capillary porosity to the total porosity being 47.63 % and 45.75 %, respectively. Adding recycled plastics reduces the total porosity of concrete, changes the pore size distribution, and reduces the fractal dimension of small pores while increasing the fractal dimension of large pores. In addition, the addition of recycled plastic increases the order of hydrated calcium silicate gel in concrete, and enhances the compactness of gel structure. Recycled plastic concrete exhibits three stages of instantaneous strain, deceleration creep, and stable creep after various levels of stress loading, and the creep amount gradually increases with the increase of loading stress. Based on the creep damage characteristics of recycled plastic concrete, a damaged viscous element is connected in parallel with a plastic element to construct a damaged viscous plastic element. Based on the Burgers model, a creep model considering the influence of material parameters was established to describe the creep attenuation stability acceleration stages. It was verified that the model can accurately reflect the creep behavior of recycled plastic concrete at different stages. In addition, parameter sensitivity analysis indicates that as the replacement rate of recycled plastics increases, concrete will enter the creep acceleration stage earlier. This study can provide theoretical basis for the performance optimization and engineering application of recycled plastic concrete.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"485 ","pages":"Article 141947"},"PeriodicalIF":7.4,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144139780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FG-cement composites are a common method for treating FG; however, the use of ordinary Portland cement as an auxiliary binder presents several issues, including high energy consumption during production, low mechanical strength, poor water resistance, and a high risk of fluoride leaching. This study proposed an FBF material based on multi-source solid wastes, which could enhance mechanical properties, improve water resistance, and reduce the risk of fluoride leaching. In FBF materials, FG was the primary component, while industrial by-products, such as ground granulated blast furnace slag (GGBS) and fly ash (FA), were utilized as precursors. Additionally, 0–3 wt% CaO (relative to the dry weight of FG) was employed as both a neutralizing agent and an alkali activator. Results indicate that an optimal CaO addition of 1.5 wt% effectively neutralizes FG acidity and promotes balanced hydration. This facilitates the formation of ettringite (AFt) and substantial calcium aluminosilicate hydrate (C-(A)-S-H) gel through the activation of GGBS and FA. Notably, fluoride immobilization is significantly enhanced, with minimum leaching observed at 1.5 wt% CaO, attributed to synergistic effects including chemical fixation (such as CaF₂ formation) and physical encapsulation within the denser microstructure developed.

Molecular dynamics simulations were conducted to investigate the microscopic attenuation mechanism of the interface between six typical oxides and asphalt under the action of moisture.

The dataset comprises mastics with varying RAP contents, ranging from 0 % to 100 %, and includes two warm mix additives, Aspahmin and Sasobit. The multivariate discriminant analysis using PLSR-LDA effectively differentiated bituminous mastics based on RAP concentrations and warm mix additives, identifying significant wavenumbers with high normalized variance importance in projection (VIP) scores. Based on these normalized VIP scores, RAP concentrations were accurately identified by the absorption peaks at 1200–1145 cm⁻¹ (aliphatic C–H bending vibrations) and 836–785 cm⁻¹ (C–H bending vibrations in long-chain hydrocarbons) achieving an overall accuracy of nearly 80 %. In contrast, warm mix additives were effectively classified using the peaks at 735–713 cm⁻¹ (Sasobit marker), 1135–900 cm⁻¹ (Asphamin marker), and 2945–2875 cm⁻¹ (C–H stretching in aliphatic hydrocarbons) with an accuracy exceeding 95 %. To further distinguish between different bitumen classes, the CatBoost classifier was employed, evaluating the absorption ranges based on feature importance values. The highlighted absorption peaks showed that RAP inclusion in bituminous mastics introduces aging-induced chemical components into the blended binder, such as aliphatic C–H bending vibrations and oxygen-containing compounds. This observation suggests that the blending between RAP binder and virgin bitumen can be chemically tracked using FTIR spectroscopy and multivariate discriminant analysis, proposing this approach for gauging the blending degree in future works.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"485 ","pages":"Article 141822"},"PeriodicalIF":7.4,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144139738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Empirical correlations were established between the results from NDT and the compressive strength determined through traditional destructive testing (DT) techniques performed in a controlled laboratory setting. The research focuses on two specific NDT methods: the Rebound Hammer Test (RHT) and Ultrasonic Pulse Velocity Test (UPV), alongside their integration into a combined approach referred to as the SonReb method. The RH method utilises the Q-value, a dimensionless parameter derived from the ratio between the kinetic energy measured of the reflected and forward hammer mass. The UPV test involves measuring the speed of ultrasonic waves travelling through the solid brick material. A total of 234 DT and 476 NDT were conducted on both modern and historical SFC bricks. The research accurately validates the application of the RHT on SFC bricks for determining compressive strength from the Q-value. Additionally, the study validates the SonReb method by testing SFC bricks and comparing the experimental compressive strength NDT value with obtained through DT. A novel empirical equation is proposed to estimate the compressive strength of the SFC bricks based on the SonReb method.

In addition, the problems caused by the storage of industrial solid waste, such as weathered ore powder (WOP), were becoming increasingly serious. Therefore, this study developed WOP to prepare BCB to solve these problems. The optimal conditions for preparing BCB in this system were with 72 wt% WOP, sintering at 1143 ℃ for 120 min. Under this condition, the linear shrinkage, volume density, water absorption and compressive strength of BCB were 4.91 %, 3.17 g/cm³, 1.69 % and 99.9 MPa, respectively, meeting the performance requirements for Class I products in the Chinese standard GB/T 4100 −2015. More specifically, the mineral compositions of BCB prepared in this system were quartz, andesine, mullite and hematite, with contents of 20.17 %, 33.95 %, 15.07 % and 7.13 %, respectively. In addition, the fluxing ions (Fe³⁺, Mg²⁺, K⁺ and Na⁺) contained in this system can weaken the Si−O and Al−O bonds by capturing electrons of O atoms, promoting the cracking of quartz and corundum crystals to form a high−temperature liquid phase. Moreover, Fe³⁺ was solid dissolved into the mullite crystal by replacing Al³⁺, thereby improving the stability of mullite crystal. It is worth noting that the fluxing mechanism and doping modification mechanism jointly promote the low−temperature formation of mullite. After 40 freeze−thaw cycles, the frost resistance coefficient of BCB can reach 94.59 %, with a compressive strength of 94.5 MPa, due to the low water absorption and mullite−interspersed structure of the brick body. The leaching toxic substance of BCB products was heavy metal Cr, with a concentration of 0.01 mg/L, which meets the requirements of the Chinese standard HJ 297 −2021 and the European standard EN 14411.

Natural brucite was employed as a magnesium source to fully substitute for dead-burned MgO in the preparation of MPC. The feasibility of converting natural brucite into struvite in the MPC system was investigated. Changes to reaction process, strength development, reaction products, microstructure, and pore structure of brucite-based MPC after adding citric acid and urea were explored. Results show that the precipitation of struvite in the brucite-based MPC system occurred rapidly, with a setting time of only 13 min. The addition of citric acid suppressed the reaction of brucite by its adsorption and coordination mechanisms, thereby extending the setting time and reducing the reaction-released temperature of brucite-based MPC. Despite this, the addition of citric acid enhanced the early compressive strength of brucite-based MPC by increasing the crystallinity of struvite, while decreased the later one by increasing the content of macropore, which resulted from the reduced forming content of struvite. The addition of urea further prolonged the setting time and reduced the reaction-released temperature of brucite-based MPC containing 2.0 wt% of citric acid, attributed to its endothermic reaction forming carbonic acid, which ultimately transformed into magnesite. However, the addition of urea reduced both the early and later compressive strength of brucite-based MPC containing 2.0 wt% of citric acid, as it increased the total pore volume and macropore content, caused by the reduced amorphous phase content.
