To investigate its dynamic mechanical properties, electromagnetic-driven split Hopkinson pressure bar techniques were employed to test LF-LAMOC specimens with varying water-to-binder ratios under impact loading. High-speed photography and digital image correlation methods were utilized to reveal the dynamic compressive and tensile fracture behaviors of LF-LAMOC. Scanning electron microscopy was applied to observe the thickness variation of the interfacial transition zone (ITZ) between magnesium oxychloride cement paste and lightweight aggregates as a function of water-to-binder ratio. Results show that LF-LAMOC exhibits significant strain-rate sensitivity in dynamic compressive/tensile strength and energy dissipation. At low impact velocities, energy dissipation is dominated by plastic and inertial energy, while energy consumed by inter-particle fracture damage is relatively minor. Under low strain rates, dynamic compressive failure of LF-LAMOC specimens manifests as splitting failure primarily caused by tensile stress. For dynamic tensile loading, cracking in disk specimens originates from the center. At high strain rates, failure transitions to pulverization, driven by combined tensile and shear stresses, with cracking initiating from both ends of the disk. Limestone powder effectively enhances the bond strength between aggregates and paste, while ITZ thickness increases with rising water-to-binder ratio. A modified Zhu-Wang-Tang dynamic constitutive model incorporating material damage was developed to derive the dynamic constitutive equation for LF-LAMOC, which demonstrates favorable predictive capability for the material’s dynamic stress-strain relationships. The conclusions obtained in this study provide valuable references for the engineering applications of LF-LAMOC.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"516 ","pages":"Article 145687"},"PeriodicalIF":8.0,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147387083","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}

This study investigated the shear load-slip behavior of Perfobond Leiste (PBL) connectors embedded in UHTCC through experimental, numerical, and theoretical approaches. A total of 14 push-out tests were conducted to examine the effects of geometric parameters. Experimental results reveal that UHTCC significantly enhances the deformation capacity of the connectors, with the ultimate slip of UHTCC-encased specimens being 7.6 times that of NC specimens. Quantitative analysis of the group hole effect indicates that the average per-hole shear capacity and initial stiffness in double- and triple-hole connectors are reduced to approximately 80 % and 65 %, respectively, compared to single-hole connectors. Finite element models validated against experimental data enabled extended parametric studies. Based on the results, a theoretical model for shear capacity was developed. A critical hole spacing of 4.65 times the hole diameter was identified, beyond which the group hole effect becomes negligible. Furthermore, a calculation formula for initial shear stiffness was derived using elastic foundation beam theory, effectively capturing the synergistic dowel action between the penetrating rebar and the UHTCC. Validation confirms that the proposed capacity and load-slip models exhibit high predictive accuracy. These findings provide a robust theoretical basis and design guidance for the implementation of PBL connectors in steel-UHTCC composite structures.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"516 ","pages":"Article 145717"},"PeriodicalIF":8.0,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147387081","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 mechanical and durability properties of hybrid fiber-reinforced phase change concrete (HFRPCC) were systematically investigated, with microstructure analyzed via SEM and MIP to elucidate the synergistic mechanisms between fibers and PCM. Results indicate that while PCM reduces mechanical properties, the incorporation of hybrid fibers effectively offsets this negative effect. With 4 % PCM (P4CC), the frost resistance was significantly enhanced, showing only 3.43 % mass loss after 200 freeze-thaw cycles. HFRP4CC (with 4 % PCM) exhibited a 38.5 % reduction in mass loss and an 8.3 % increase in relative dynamic elastic modulus compared to hybrid fiber-reinforced concrete (HFRC), demonstrating superior freeze-thaw resistance. Nano-SiO₂ from the PCM carrier refined the pore structure, while hybrid fibers promoted C-S-H gel formation and enhanced interfacial bonding, synergistically mitigating frost damage. The fiber network also restrained PCM-induced pores and optimized pore distribution, reducing penetration depth and relative permeability coefficient by 9.5 % and 25 %, respectively, compared to HFRC. Although PCM slightly increased electrical flux, the porosity-filling and ion-blocking effects of fibers maintained HFRPCC’s impermeability advantages. After 100 thermal cycles, the mechanical properties exhibit a decrease of less than 3 %, demonstrating good stability under phase-change cycling. The developed HFRPCC combines thermal regulation and structural optimization, significantly improving mechanical properties, freeze-thaw resistance, and impermeability, offering a high-performance solution for concrete engineering in extreme environments.</div></div>","PeriodicalId":288,"journal":{"name":"Construction and Building Materials","volume":"516 ","pages":"Article 145692"},"PeriodicalIF":8.0,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147387160","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}

Thus, we investigate a thermo-mechanical recovery (TMR) process for the recovery and activation of RCP from industrial concrete waste. We found that the TMR process results in an RCP recovery rate of 8.5 % whereas a conventional jaw crushing method could only recover 1.1 % of RCP. In addition, the TMR process effectively recovers and activates cementitious phases in the recovered RCP, resulting in approximately 29 % reactive phases, primarily comprising dehydrated phases (belite and brownmillerite) and residual unhydrated cement phases, together with about 34 % amorphous phases, based on the total mass of the RCP. This leads to the significant rehydration effect of TMR-RCP with comparable strength at 3 and 7 days for 10–40 % cement replacement levels while 28-day strength at 40 % replacement level reaches 77 % of the cement control sample.
