An artificial random generation technology has been extensively implemented for mesoscopic modeling of asphalt mixtures. However, during the aggregate assembly process, conventional random packing method struggles to achieve dense aggregate spatial arrangements, especially in 3D modeling. To address this limitation, a high-density packing method that optimizes the geometric centers and three-axis rotation angles of aggregates using a genetic algorithm was developed, based on rigid body motion principles. This approach was applied to construct a mesoscopic numerical model of an AC-13 asphalt mixture with an 82 % aggregate placement rate. Furthermore, uniaxial compression simulations using the generated model demonstrated strong agreement with experiments, predicting macro-dynamic modulus values within 20 % deviation from the physical test.

Nevertheless, the microwave thermal response of asphalt mixtures containing encapsulated rejuvenators has not been fully characterized. In this study, the microwave heating characteristics and their correlation with the self-healing behavior of asphalt mixtures containing rejuvenator-loaded fibers were systematically investigated. The critical self-healing temperature was determined via frequency sweep tests conducted using a dynamic shear rheometer. Infrared thermography was then employed to examine temperature distribution and evolution during microwave heating and subsequent natural cooling. Two novel indicators—healing duration and healing energy—were introduced to correlate thermal-temporal parameters with self-healing potential. Results showed that the critical self-healing temperature decreased with increasing asphalt penetration grade and was slightly lower than the corresponding softening point. The incorporation of rejuvenator-loaded fibers enhanced microwave heating rate and improved temperature uniformity. A minimum irradiation time of 40 s was required for effective self-healing. The majority of healing occurred during the cooling phase rather than during microwave irradiation. Extended microwave irradiation time was the critical factor in cold environments, while employing a high fiber content was highly advantageous in warm environments.

Eight mixtures of NA and RAP were tested in a large direct shear machine under normal stresses of 50, 100 and 150 kPa, generating 1440 records. Increasing RAP content consistently reduced peak shear stress and friction angle while raising cohesion, indicating a transition from friction dominated to binder-assisted resistance. Field emission scanning electron microscopy (FESEM) confirmed this mechanism by revealing angular, rough asperities on uncoated NA and smoother, bitumen sheathed surfaces on RAP, which diminish inter-particle interlock but add adhesive bonding. Four easily measured variables such as RAP percentage, complementary NA percentage, seating load and horizontal displacement were used to train artificial neural network (ANN), random forest (RF) and extreme gradient boosting (XGB) models on 80 % of the data while the remaining 20 % was used as an independent test set.

This study systematically investigates strategies to mitigate this inhibition in SSA-Ordinary Portland Cement (OPC) systems by comparing the effects of mechanical activation versus chemical activation (using Na₂SO₄, CaSO₄, and Triethanolamine (TEA)) on early-age hydration kinetics and mechanical properties. Results reveal that, contrary to the activation behavior of traditional SCMs, mechanical activation exacerbates phosphorus leaching from SSA, thereby retarding the early hydration process. In contrast, chemical activation can overcome this limitation via targeted regulation of the hydration of different clinker phases. Specifically, 1 % Na₂SO₄ accelerated early hydration by promoting C₃S dissolution, increasing the 3-day strength by 127 %, while simultaneously suppressing excessive U-phase formation to maintain late-age strength. 5 % CaSO₄ synergistically accelerated the hydration of both C₃S and C₃A, thereby enhancing the formation of C-S-H and AFt, which culminated in compressive strength enhancements of 190 %, 47 %, and 23 % at 3, 7, and 28 days, respectively, relative to the reference mixture. 0.01 % TEA selectively promotes C₃A hydration while minimizing the inhibitory effect on C₃S.

This research specifically focuses on nine representative sandstone types: Agra Red, Jodhpur Beige, Kandla White Beige, Teak Wood, Mandana, Dhrangadhra Pink, Jodhpur Brown, Bansipaharpur and Gwalior Mint, collected from active quarries across different regions of India.

Results highlight significant variability in the properties of the sandstones, reinforcing the importance of site-specific characterization.

Although most research in this area has focused on cement-based systems, lime-based mortars remain relatively underexplored despite their importance in sustainable construction and heritage preservation. This study investigates the impact of carbon microfibers (CMFs) as a functional filler on the mechanical, electrical, and piezoresistive properties of hydraulic lime-based mortars. Mortar and paste mixes were prepared with different dosages of CMF (0 %, 0.05 %, 0.1 %, and 0.2 % by weight of the binder), both with and without silica fume as a pozzolanic additive. Mechanical tests, including flexural and compressive strength, as well as electrical resistivity measurements and electromechanical (piezoresistivity) evaluations, were performed. The results show that while silica fume enhances compressive strength, it tends to lower flexural strength, likely due to increased brittleness. The addition of CMF exhibited a nonlinear influence on the mechanical properties of the mixes, with strength decreasing up to 0.1 % CMF, followed by a slight increase at 0.2 % CMF. Similarly, the electrical properties (particularly piezoresistivity) also followed a nonlinear trend, showing enhanced sensitivity up to 0.1 % CMF and a reduction beyond that point. These trends suggest the presence of a percolation threshold around 0.1 % CMF The piezoresistive performance, assessed through gauge factor and linearity, also reached its peak at this dosage. The formulation of 0.1 % conductive material mixed with silica fume achieved a gauge factor of 311, which is 34 % higher than the mix containing 0.0 % CMF. This mix also displayed a coefficient of determination (R²) of 0.97. In contrast, the mix without silica fume attained a gauge factor of 339, representing a 79 % increase compared to the mix with 0.0 % CMF, with an R² of 0.94. These results confirm that the sensing response was stable and highly reliable. Overall, 0.1 % CMF was identified as the optimal amount for improving the self-sensing behaviour of lime-based mortars. These findings confirm that CMF can effectively enhance the electromechanical response of traditional lime matrices without compromising their structural performance or their suitability for heritage materials.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"497 ","pages":"Article 143933"},"PeriodicalIF":8.0,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145264413","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}
