During fires, flames rapidly propagate through these structures, exacerbating fire spread. In this work, a novel ceramifiable, rapid-expansion, and highly efficient fire-resistant sealing system was developed, based on silicone rubber composites (CSR) incorporated with sodium silicate (SS) and low-melting-point glass powder frits (GF) as fillers. The effect of the SS and SR matrix on the expansion behavior of CSR and the structure of the obtained ceramic was investigated. The synergistic mechanism of SS and GF for improving the fireproofing and plugging of silicone rubber was also intensively discussed. It was found that CSR expanded by 4.49 times in volume at 500 °C for 5 min and transformed into a rigid ceramic foam with a compressive strength of 16.1 MPa after treating at 700 °C. CSR exhibited prolonged resistance to 1300 °C flame ablation with the backside temperature of only 128.5 °C after 10 min. During fire exposure, the morphology and crystal structure of CSR were transformed, forming a multi-level structure from exterior to interior, including the cristobalite protective layer, porous ceramic layer, expanded insulation layer, and internal matrix. In addition, the composites can reach the 3 h level of the fire sealing test for cracks, with backside temperatures only 70.8 °C and no flame penetration. This work provides novel insights into the design of ceramifiable silicone rubber systems and expands their potential applications in real fire scenarios.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"496 ","pages":"Article 143801"},"PeriodicalIF":8.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218502","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}

Hydration products such as calcium silicate hydrate (C-S-H), calcium aluminate hydrate (C-A-H), and Ca(OH)₂ (CH) significantly inhibited spore germination, while ettringite (AFt) and monosulfate (AFm) exhibited a retarding effect.

High concentrations of OH^- demonstrated significant inhibitory effects. Additionally, C-S-H induced spore agglomeration and adsorption, thereby preventing germination.

The internal curing efficiency is closely linked to the pore size of internal curing material, particularly ink-bottle structure, which plays a crucial role in moisture retention and release. This study investigates how the pumice ink-bottle pore size affects moisture transmission kinetics in UHPC. Using low-field nuclear magnetic resonance, scanning electron microscopy, and nanoindentation, the impact of pore characteristics on the absorption-desorption behavior of internal curing water and its correlation with UHPC microstructural evolution were investigated. The results reveal that ink-bottle hysteresis effect is more pronounced in finer pumice, with the hysteresis index of 0–0.6 mm pumice increasing by 42 % compared to 0.6–1.23 mm pumice. Consequently, fine pumice exhibits a delayed water release time (by 1 h) and a lower water release rate, with 38 % less water being released over 24 h in UHPC. When fine pumice content reaches 20 %, it reduces autogenous shrinkage by 71 % and forms a hydration product gradient layer than 45 μm in the interface transition zone of UHPC, demonstrating a more effective internal curing effect. Absorption process in ink-bottle pores is driven by capillary forces and osmotic pressure, while cavitation occurs via bubble nucleation under low vapor pressure. A dynamic moisture transfer model based on vapor pressure theory confirms that smaller ink-bottle pores amplify hysteresis effects and thereby enhance the efficiency of internal curing.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"496 ","pages":"Article 143839"},"PeriodicalIF":8.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218510","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}

Therefore, this work conducted the soaking aging and dry-wet cycle aging on SBS modified asphalt, respectively. The physical properties and rheological properties of the SBS modified asphalt was measured. Subsequently, a molecular dynamic (MD) simulation was conducted to reveal the underlying mechanism of this aging behavior. Results indicated that in the early stage of aging, SBS modified asphalt exhibited an abnormal phenomenon of a decrease in softening point and an increase in penetration regardless of the aging types, which was due to the breakdown of the SBS molecular network, and this abnormal phenomenon disappeared in the later stage of aging. Besides, there is a proportional relationship between salt concentration and the aging degree of SBS modified asphalt. Additionally, the calculated results of molecular dynamic (MD) simulation revealed that salt ions can reduce the fractional free volume (FFV) of the SBS modified asphalt and increase the interaction between asphalt molecules, which hinders the movement of asphalt molecules, leading to the increasing stiffness of aged SBS modified asphalt.
