However, the production of hot mix asphalt (HMA) with reclaimed asphalt pavement (RAP) generates a high heat rate, leading to the stiffening of the asphalt binder and the release of toxic gases. Warm Mix Asphalt (WMA) is a cost-effective technique that softens and delays the aging of the asphalt binder while producing asphalt mixtures at lower temperatures, resulting in decreased energy usage and harmful pollutants. However, increasing the RAP content in WMA mixtures could have a detrimental impact on several asphalt mixture properties, such as fatigue and moisture resistance. Consequently, increasing the RAP content in WMA mixes could require devising a strategy to offset the drawbacks of RAP material. Fibers are recognized as one of the additives that are incorporated directly into the mixes and improve the fatigue and moisture resistance of asphalt mixtures. Therefore, this study is conducted to evaluate the impact of ceramic fibers (CFs) on the performance of WMA-RAP mixtures. The response surface methodology (RSM) was employed to find out how the CFs changed the responses of WMA-recycled asphalt mixes at low and intermediate temperatures. These responses included Marshal stability, rutting resistance, moisture susceptibility, and fatigue life resistance. RSM was used to find the best amounts of factors like CFs, WMA additive (Sasobit), and RAP using central composite design (CCD). The results of the analysis of variance (ANOVA) showed a significant interaction between the CFs, RAP, and Sasobit. The CFs significantly improved every studied attribute, particularly the fatigue life at 5 °C and 20 °C. The excellent value of the adjusted coefficient of determination (adjusted R2) of all responses indicates a excellent correlation between the model and experimental results. The outcomes of the validation test demonstrate that every response has a percentage error of less than 5 %, exhibiting strong agreement and the accuracy of the model.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"455 ","pages":"Article 139230"},"PeriodicalIF":7.4,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663734","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}

The results indicated that the thermal stability of the saturate and aromatic fractions was poor, while the resin and asphaltene components exhibited better thermal stability during combustion. The thermodynamic properties of the selected flame retardant materials were matched with different asphalt components. Three flame retardant systems were designed, and the final composition ratio was determined using orthogonal experiments and the entropy method. Compared to single and binary flame retardant systems, the asphalt with the three-component flame retardant system showed significantly better flame retardant performance. The softening point difference of asphalt increased continuously with higher flame retardant dosages. To maintain storage stability, the flame retardant content should be controlled below 12 %. Despite some agglomeration, most flame retardants were present as individual particles, indicating good dispersion in the asphalt.

The combined effects of high-temperature rock mass and low-temperature environments can cause Temperature Difference (TD) damage to the surrounding rock. However, GCI's shear mechanical behavior and mechanisms under various TDs require further investigation. This study conducts direct shear tests of GCI damaged by different TDs ((90°C, −30°C), (100°C, −20°C), (110°C, −10°C), and (120°C, 0°C)). It analyzes the impact of TD damage on the shear strength, three-dimensional morphology of shear fractures, and acoustic emission (AE) characteristics of GCI. The results indicated that as temperature increases, the shear strength of GCI improves, and the concrete volume loss in shear fractures diminishes. Under various TD paths, the cumulative energy curve of AE exhibits an 'S' shape. TD has a minimal impact on the precursor (b-value decrease) of GCI failure. The shear damage constitutive model created using a piecewise function struggles to represent the influence of TD damage. In contrast, the stress-strain prediction model based on data-driven approaches demonstrates broad applicability. Thermal expansion caused by high temperatures facilitates increased friction between mineral particles, enhancing the shearing strength of GCI (for 120°C, 0°C). In addition, high temperatures lead to the evaporation of free water and affect the freezing of GCI at low temperatures. When the temperature falls below −20°C, frost heave damage contributes to the deterioration of GCI shear strength.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"455 ","pages":"Article 139192"},"PeriodicalIF":7.4,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663774","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}

In this article, the formation of C₂A_xF_1–x-type aluminoferrites in the CaO–Al₂O₃–Fe₂O₃ system during solid-phase reactions was studied. A system of empirical equations has been proposed that allows calculating the thermodynamic functions (Δ_f<em>H</em>°₂₉₈, Δ_f<em>G</em>°₂₉₈) of the formation of calcium aluminoferrites of any composition within a continuous series C₂A₀_.₆₆₇F₀_.₃₃₃ (C₆A₂F) – C₂F. Analysis of the various pathways of aluminoferrites formation has been conducted, taking into consideration the formation of intermediate phases in the ternary system. Based on a comparison of experimental data for mixtures of C+F, C+A, and C+A+F, a temperature sequence for phase formation (C₂F, CF, amorphous [CA]_am, C₂(A)F, CA, C₁₂A₇, C₂A_xF_1–x, eutectic liquid) in ternary oxide systems has been established. It has been shown that the amorphous aluminate phase present in the reaction system within the temperature range of 850–1100°C plays a crucial role in the formation of aluminoferrites. Among the investigated ternary oxide mixtures, whose initial composition corresponds to the stoichiometries of C₆A₂F, C₄AF, C₆AF₂, and C₈AF₃, only a certain aluminoferrite (brownmillerite), with a sufficiently high yield (∼53 wt% at 1200 °C), is formed in a 4 C+A+F mixture.

This study investigated the feasibility of preparing recycled UHP-SHCC by simultaneously substituting both cement and silica sand with WGF. WGF, abundant in amorphous components, exhibited favorable pozzolanic activity and filling effect. Substituting high-volume cement with WGF negatively impacted the hydration reaction and micro-properties of UHP-SHCC matrix, while replacing silica sand with WGF improved hydration reaction and micro-structure. Generally, substituting WGF for both silica sand and cement decreased the maximum cumulative hydration heat of UHP-SHCC. The drying shrinkage resistance of UHP-SHCC is improved with WGF replacing an appropriate dosage of cement and silica sand. The compressive and flexural strengths of UHP-SHCC declined as the high-volume replacement of cement with WGF, but improved with an increase in the proportion of silica sand substituted. Simultaneously substituting cement and silica sand with WGF can yield recycled UHP-SHCC with mechanical strengths comparable to those of reference UHP-SHCC. The ductility of UHP-SHCC exhibits a trend of first increasing and then decreasing as the proportion of cement substituted by WGF increases, while it decreases with the addition of WGF as silica sand replacement. Simultaneously substituting both cement and silica sand with WGF can obtain more sustainable UHP-SHCC with high strength and ductility.
